Learning objectives The purpose of this exhibition is: Review common and uncommon cases related to the pericardial sinuses and recesses; Correlate important findings with the pericardium anatomy; Discuss imaging findings according to the pericardium anatomy to enhance radiologists’ skills; Highlight their characteristics for radiologists with these conditions, avoiding unfavorable patient outcome; Despite its characteristic density, describe the importance of distinguishing them from pathologic process, as mediastinal cysts, masses and lymphadenopathies; Correlate with the impact on the onco-image;
Read more Background The pericardium, consisting of a fibroserous sac that encloses the heart, is routinely imaged on radiologists’ daily practice. Despite its imaging characteristics delineating the cardiovascular anatomy, pericardial sinus and recesses must be promptly distinguished from pathologic process, as mediastinal lymphadenopathy, thrombus, mediastinal cystic masses and other lesions, avoiding unfavorable patient outcomes.
Read more Findings and procedure details ANATOMYThe pericardium is a fibroserous sac, that encloses the heart, consisted of two main components: serous pericardium: smooth and glistening lining that is covered by mesothelium. visceral layer (epicardium): surrounds the heart and great vessels. parietal layer: lines the fibrous component. fibrous pericardium: strong and inelastic due to interlacing collagenous fibers. [fig 1] The reflections of the serosal layers are arranged around two complex tubes, with the transverse sinus as the passage between them: one tube encloses the aorta and pulmonary trunk. the other tube encloses the superior vena cava,...
Read more Conclusion We reviewed the applied anatomy of pericardium with the evaluation of cases of recesses and sinus, and the main and the main pathologies that affect it. Radiologists' familiarity with pericardium, its recesses and sinuses, is important to avoid misdiagnosis.In the radiological reports, mainly of cancer patients, it is essential to recognize the pericardial recesses and sinus to avoid misunderstandings with lymph nodes and masses that could lead to diagnostic and therapeutic errors and mistakes.
