Pericardial recess definition. Thus, the superior aortic recess is referred to as the aorto-caval recess. This webpage provides an approach to diagnosing pericardial effusion, including clinical evaluation and diagnostic techniques. Apr 9, 2025 · The pericardial recesses are small spaces in the pericardial cavity formed by reflections of the pericardium. The purpose of this study was to assess the prevalence and CT features of the high-riding superior pericardial recess. The sac is called the pericardium. The pericardial cavity is involved in many inflammatory and malignant diseases. It is important to be aware of the normal anatomy of the pericardium as it is often mistaken for normal variants and/or disease. As the pericardial layers reflect over the great vessels and the heart, they form sinuses and recesses, which … pericardial effusion, the buildup of fluid in the sac cardiac tamponade, a serious problem in which buildup of fluid in the sac causes problems with the function of the heart symptoms of pericardial problems include chest pain, rapid heartbeat and difficulty breathing. With advances in multidetector computed tomography (CT) technology, pericardial recesses are frequently detected with thin-section CT. Learn to perform the FAST (Focused Assessment with Sonography in Trauma) exam for detecting free fluid in trauma patients with SAEM's M3 curriculum. Thin-section computed tomography (CT) has improved the detection of pericardial recesses and sinuses. Knowledge of pericardial anatomy on imaging is crucial to avoid misinterpretation of fluid-filled pericardial sinuses and recesses as adenopathy/pericardial metastasis or aortic dissection, which can impact patient management and treatment decisions. The most dependent recess of the peritoneal cavity in the supine position is in the pelvis. Between the rectum and bladder in men is a pouch of peritoneal cavity that extends slightly below the level of the seminal vesicles. Gross anatomy Pericardial fluid can pool in these recesses and can be categorized by whether they arise from the transverse sinus, the This recess may extend into the high right paratracheal region (Figure 62. 13,20,21 Because of the merging of the serosal layers at two distinct points, the reflections of the serous pericardium become arranged as two The right cardiophrenic angle is the clinical term for the right phrenicomediastinal recess on medical imaging (X-ray, CT). The depth of the pulmonary venous recesses varies between individual hearts depending on the extent of invagination of the visceral pericardium around the superior and inferior pulmonary veins. The mediastinum contains vital vascular and nonvascular organs and other structures, and a wide variety of neoplasms and other abnormalities may originate from this anatomic region of the chest. Mar 24, 2024 · The pericardium comprises a double-walled fibrous-serosal sac that encloses the heart. In the case of pericardial effusion, cardiac tamponade can occur and must be treated The right and left pulmonary venous recesses are formed by the pericardial reflection between the respective superior and inferior pulmonary veins (Fig 14). But if the pericardium is diseased or injured, too much fluid can collect in the area. Become a Gold Supporter and see no third-party ads. Pericardial recesses arise from pericardial cavity proper, transverse sinus, or oblique sinus Pericardial cavity proper gives rise to right pulmonic vein recess, left pulmonic vein recess, and postcaval recess The pericardial sac serves as a physical barrier that protects against the contiguous spread of infection or neoplasm within the mediastinum and also allows for potential targeted drug delivery that limits the concentration and action of the drug to the heart. OBJECTIVE. 5). The pericardial sac serves as a physical barrier that protects against the contiguous spread of infection or neoplasm within the mediastinum and also allows for potential targeted drug delivery that limits the concentration and action of the drug to the heart. The heart is viewed from the anterior (left upper panel), right lateral (left lower panel), and left lateral (right lower panel) directions, showing anterior pericardial reflection, bilateral pulmonary hila and phrenic nerves, and the sterno-pericardial ligament. Reflections of the serosal layer form sinuses and recesses. pericardial effusion, the buildup of fluid in the sac cardiac tamponade, a serious problem in which buildup of fluid in the sac causes problems with the function of the heart symptoms of pericardial problems include chest pain, rapid heartbeat and difficulty breathing. There are also smaller Pericardial sinuses are main pericardial recesses formed by reflections of the pericardium over vascular and cardiac structures. Knowledge of pericardial anatomy on imaging is crucial to avoid misinterpretation of fluid-filled pericardial The pericardial recesses can be categorized on the basis of whether they arise from the pericardial cavity proper, the transverse sinus or the oblique sinus [4]. In these patients, differentiation from mediastinal lymphadenopathy or mass was difficult. The peritoneal cavity has several recesses into which exudate may become loculated. This chapter discusses the embryology and anatomy of the pericardial cavity. Depending on the various locations and appearances of fluid-filled pericardial sinuses and recesses on computed tomography (CT), they can be misinterpreted as adenopathy/metastasis, a medias-tinal cyst, or an aortic dissection. Radiologists must first be familiar with the normal anatomic structures of the heart and pericardium (eg, atria, ventricles, cardiac valves, pericardial recesses, paracardiac structures) to avoid mistaking them for pathologic processes. Procedures or surgeries to treat a pericardial effusion include: Pericardial cysts are noncancerous growths in your pericardium (sac around your heart). Pericardial space is reconstructed as the solid structure. The spaces between these two layers forming the pericardial sinuses or recesses, which are visualized when distended with fluid. The right and left pulmonary venous recesses are formed by the pericardial reflection between the respective superior and inferior pulmonary veins (Fig 14). In this review, we describe normal pericardial anatomy and illustrate imaging features to differentiate fluid in pericardial sinuses and recesses from mediastinal adenopathy. Explains symptoms, treatments, and more. Within the pericardial cavity there are several recesses where fluid can collect in close contiguity to the major bronchi and lymph nodes. As pericardial fluid volume is not easily measured, pericardial effusion can be defined as separation of the parietal and visceral layers by a sufficient amount of fluid to be detected on imaging (excluding the normal pericardial recesses). Radiopaedia’s mission is to create the best radiology reference the world has ever seen and to make it available for free, for ever, for all. One tube encloses the aorta and pulmonary trunk. The reflections of the serosal layers are arranged around two complex tubes. How long does recovery take after treatment? Recovery time varies depending on the underlying cause and treatment. You may need treatment to drain a pericardial effusion or prevent future fluid buildup if: Medicines don't fix the pericardial effusion. Along with the development of novel techniques for percutaneous access to the pericardial, increased interest in the detailed anatomy of the pericardial space and its recesses has developed. 13,20,21 Because of the merging of the serosal layers at two distinct points, the reflections of the serous pericardium become arranged as two In oncologic imaging, staging and prognostic implications of fluid in a pericardial recess misinterpreted as adenopathy can significantly alter manage-ment and therapy. Therefore, we will Nov 23, 2012 · In oncologic imaging, staging and prognostic implications of fluid in a pericardial recess misinterpreted as adenopathy can significantly alter management and therapy. CONCLUSION. Division of the mediastinum into distinct compartments Trace amounts of pericardial fluid are often a physiologic finding and do not necessarily represent an underlying disease. Cystic mediastinal masses have traditionally represented a diagnostic dilemma with differentiation of malignant masses a particular area of concern. The reflections of the serosal layer form sinuses and recesses, which are located adjacent to the arteries and veins. The pericardial space between the inner visceral and outer parietal pericardium is di-vided into the pericardial cavity proper and the pericardial sinus, which connect the pericar-dial recesses. Discover pericardial effusion's causes, symptoms, and treatment options. 4). We review the anatomy of the pericardium with emphasis on the pericardial recesses that can potentially be misinterpreted as adenopathy. 8 Pericardial fat is best seen on the transgastric views and can be seen in the ME four-chamber views. The space between these layers often has a thin layer of fluid. In this review, we describe normal pericardial anatomy and illustrate imaging features to differentiate uid in pericardial fl sinuses and recesses from mediastinal adenopathy. These spaces are not distinct compartments but are everal pericardial recesses are created by the transverse pericardial sinus, and may be mistaken for dissection or lymphadenopathy 3 Adjacent to these sinuses, there may be one or several pericardial recesses: The reflections of the serosal layer form sinuses and recesses, which are located adjacent to the arteries and veins. However, many rheumatologic conditions can cause inflammation of the lining of the heart which could also lead to trace amounts of fluid. The transverse sinus is between the aorta, pulmonary trunk and the atria and pulmonary veins. We recently observed patients in whom the superior pericardial recess extended cephalad (“high-riding”) into the right paratracheal region. We review the anatomy of the pericardium with emphasis on the pericar-dial recesses that can potentially be misinter-preted as adenopathy. These include the transverse sinus, behind the ascending aorta and pulmonary trunk; the oblique sinus, behind the left atrium; and the left pulmonic recess, between the left pulmonary artery and the left superior pulmonary vein. The reflections of the serosal layer are arranged as two tubes: Cardiologist explains what fluid around the heart - pericardial effusion - means for your health. The inferior aortic recess is an extension of the transverse sinus that lies between the lower part of the ascending aorta and the right atrium. This space is an integral access point for epicardial interventions. Each imaging modality has strengths and weaknesses in mediastinal imaging—computed tomography (CT) The inferior aortic recess reaches close to the nadir of the noncoronary aortic sinus. Physiologic fluid in the pericardial recesses and sinuses can mimic mediastinal adenopathy. A large pericardial effusion causes symptoms and increases the risk of complications. They rarely cause symptoms but may put pressure on your heart or lungs. Learn why early diagnosis of fluid around the heart is vital to prevent risks. 3 The pericardial cavity normally contains <50 mL of serous fluid which lubricates Recesses of the pericardial cavity proper are postcaval recess, right pulmonic vein recess, and left pulmonic vein recess. 4 Techniques for the FAST Exam Above the diaphragm, this fluid collection indicates emergent action in the form of a pericardial or pleural effusion. A pericardial recess is frequently seen in patients undergoing chest computed tomography (CT). Is pericardial effusion serious? Yes, pericardial effusion can be serious, especially if it leads to cardiac tamponade, which is a life-threatening condition requiring immediate medical attention. Although echocardiography is the usual initial imaging modality chosen to detect and characterize pericardial effusions, MRI is nonetheless helpful in various circumstances. Red circles indicate bilateral pulmonary venous recess, although it should be noted that this patient does not show a prominent left pulmonary venous recess due to the left common pulmonary vein. There are also smaller pericardial recesses including posterolateral to the superior vena cava and between the inferior vena cava and coronary sinus [4]. 11. You have a complication called cardiac tamponade. It has two layers. Pericardial sinuses are main pericardial recesses formed by reflections of the pericardium over vascular and cardiac structures. We anticipate our report serving as a tool for education of imaging and interventional specialists. Knowledge of the anatomy of the pericardium The pericardium comprises a double-walled fibrous-serosal sac that encloses the heart. The misinterpretation of pericardial recesses and other benign pericardial entities in the oncologic setting can lead to inappropriate staging and management. it is located between the heart and the diaphragm and is usually filled with fat. The superior pericardial recess can be misinterpreted as an aortic dissection, lymphadenopathy, or a cystic mediastinal mass on computed tomography (CT) imaging [7]. The oblique sinus is the posterior extension of the pericardium and lies posterior to the left atrium and anterior to the esophagus [1–3] (Figure 62. In particular, recesses may extend along the pulmonary veins (Figure 62. Recesses may also arise from the pericardial cavity proper [3]. The pericardium is composed of visceral (epicardial) and parietal (fibrous pericardial) components: the former reflects over the great vessels, creating sinuses and recesses (a major component of the pericardial reserve volume), and becomes the serosal layer of the latter, which has ligamentous at-tachments to the sternum, spine, and diaphragm.

Note the symmetry in these recesses. (Right) The transverse sinus located between the proximal great arteries and both atria. Narrow-collimation Radiopaedia’s mission is to create the best radiology reference the world has ever seen and to make it available for free, for ever, for all. Yellow circles indicate bilateral pulmonic recess. The pericardial space is filled with 400 mL of 70% ethanol. The cardiophrenic angles are obscured on X-ray in case of :Pericardial lesions:pericardial fat padpericardial cystpericardial fat necrosispericardial lipomatosisMediastinal lesions Pericardial effusion Any of the disorders that can cause acute pericarditis also may result in pericardial effusion. Overview Pericardial effusion (per-e-KAHR-dee-ul uh-FU-zhun) is the buildup of too much fluid in the sac around the heart. 3) [5, 6]. Treatment depends on the cause. Fever is a common symptom of acute pericarditis. DEFINITION AND ANATOMY OF PERICARDIAL RECESS AND SINUS Normal pericardium consists of visceral and parietal pericardium, and is less than 2 mm on CT. The pericardial cavity is a complex space consisting of the pericardial cavity proper and interconnecting cul-de-sacs known as sinuses, which are further subdivided and connected to multiple recesses. Pericardial Fat Pericardial adipose tissue, or fat, often appears as a gelatinous structure within the pericardial space adjacent to the visceral pericardium, and it is often misinterpreted as a pericardial mass. Misinterpretation of fluid in pericardial recesses as mediastinal adenopathy can lead to inaccurate clinical staging and inappropriate management. The superior aortic recess reaches close to the aortic arch anterior to the superior caval vein. . Keywords: cardiac anatomy, computed tomography, pericardial recess, pericardial sinus, pericardial space Condensed abstract: The epicardial approach has received increased attention in clinical electrophysiology. Pericardial effusion is the acute or chronic accumulation of fluid in the pericardial space (between the parietal and the visceral pericardium) and is often associated with a variety of underlying ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Knowledge of pericardial anatomy on imaging is crucial to avoid misinterpretation of fluid-filled pericardial The pericardial cavity and its boundaries are formed by the reflections of the visceral and parietal pericardial layers. Postcaval recess lies posterior and right lateral aspect of the superior vena cavae (Figure 5). mvyf, ivjj, vtr3yt, ubc3f, 2vv0qf, tfhqr, blcz, evtzq, pmefo, ygeg,
