What is pericardial recess?
The pericardial recesses are small spaces in the pericardial cavity arising from the transverse pericardial sinus that are formed by the reflections of the pericardium. Pericardial fluid can pool in these recesses, mimicking mediastinal lymph nodes or pathology.
Where is pericardial recess?
Pericardial Recesses. The pericardium surrounds the heart and extends superiorly to cover the main pulmonary artery, ascending aorta, and SVC (,Fig 10). The pericardium can be identified at cross-sectional imaging when it is outlined by mediastinal and subepicardial fat or when it contains fluid or is thickened.
What is a prominent superior pericardial recess?
The superior pericardial recess arises from the transverse sinus and is frequently seen adjacent to the ascending aorta on axial cross-sections. The transverse sinus (black arrow) lies posterior to the proximal ascending aorta, and this gives rise to the superior pericardial recess more superiorly (asterisk).
What causes pericardial thickening?
Causes of pericardial effusion include: Inflammation of the pericardium following heart surgery or a heart attack. Autoimmune disorders such as rheumatoid arthritis or lupus. Spread of cancer (metastasis), particularly lung cancer, breast cancer, melanoma, leukemia, non-Hodgkin’s lymphoma or Hodgkin’s disease.
What is a pericardial cyst?
Pericardial cysts are rare benign mediastinal masses usually detected in asymptomatic individuals. Rare complications include compression of the bronchi, ventricular outflow tract, rupture with tamponade and sudden death. Treatment in symptomatic individuals includes surgical resection or percutaneous aspiration.
What is mild pericardial thickening?
Pericardial thickening refers to an abnormally thickened state of the pericardium and may occur in inflammatory (i.e. pericarditis) as well as non-inflammatory situations.
Are you awake during pericardiocentesis?
The following is a description of catheter-based pericardiocentesis, the most common form. In general: You will be awake. An IV will be inserted in your hand or arm.
Is pericardiocentesis a surgery?
Pericardiocentesis is an invasive procedure. It uses a needle and catheter to obtain fluid from your pericardium. The fluid can then be sent to a laboratory for microscopic examination for abnormal cells. This test is often used to help diagnose an infection, cancer, or the cause of extra fluid surrounding your heart.
What is difference between tumor and cyst?
A cyst is a sac or capsule that’s filled with tissue, fluid, air, or other material. A tumor is usually a solid mass of tissue.
How are the pericardial recesses mistaken for dissection?
There are several pericardial recesses that may be mistaken for dissection or lymphadenopathy: aortic recesses superior aortic recess pulmonic recesses right pulmonic recess postcaval recess pulmonary venous recesses right pulmonary venous recess
What are the recesses of the pericardial cavity?
Dr Andrew Dixon ◉ and Dr Craig Hacking ◉ ◈ et al. The pericardial recesses are small spaces in the pericardial cavity arising from the transverse pericardial sinus that are formed by the reflections of the pericardium. Pericardial fluid can pool in these recesses, mimicking mediastinal lymph nodes or pathology.
How is cardiac magnetic resonance ( CMR ) used in pericardial disease?
Cardiac magnetic resonance (CMR) imaging has emerged as a powerful tool in the evaluation of pericardial disease. This article focuses on the MR characteristics of the most commonly encountered pericardial diseases and the adjunct role CMR can play in patient evaluation and management.
What’s the best way to visualize the pericardium?
Black-blood T1-weighted spin-echo CMR, using a fast, segmented sequence, is the best approach to visualize, the heart, pericardium and mediastinum [ 11, 12 ]. Use of a small field of view and a saturation block positioned on the frontal chest wall may hereby improve pericardial visualization.
