“…Pericardial diverticula are clinically identical to cysts and can be hard to distinguish from bronchogenic or thymic cysts if in an unusual location [37]. CT will confirm the diagnosis of a pericardial cyst by clearly demonstrating the position and extent of the lesion; fluid density and characterisation of the mass; a clearly defined ovoid mass; and absent enhancement with iv contrast [38].…”

ABSTRACT. Multidetector row computed tomography (MDCT) with its high spatial and temporal resolution has now become an established and complementary method for cardiac imaging. It can now be used reliably to exclude significant coronary artery disease and delineate complex coronary artery anomalies, and has become a valuable problem-solving tool. Our experience with MDCT imaging suggests that it is clinically useful for imaging the pericardium. It is important to be aware of the normal anatomy of the pericardium and not mistake normal variations for pathology. The pericardial recesses are visible in up to 44% of non-electrocardiogram (ECG)-gated MDCT images. Abnormalities of the pericardium can now be identified with increasing certainty on 64-detector row CT; they may be the key to diagnosis and therefore must not be overlooked. This educational review of the pericardium will cover different imaging techniques, with a significant emphasis on MDCT. We have a large research and clinical experience of ECG-gated cardiac CT and will demonstrate examples of pericardial recesses, their variations and a wide variety of pericardial abnormalities and systemic conditions affecting the pericardium. We give a brief relevant background of the conditions and reinforce the key imaging features. We aim to provide a pictorial demonstration of the wide variety of abnormalities of the pericardium and the pitfalls in the diagnosis of pericardial disease.

Cystic masses of the mediastinum are a heterogenous group of asymptomatic or symptomatic, congenital, infectious, or neoplastic lesions. For early and correct diagnosis, evaluation, and optimal patient management of cystic mediastinal masses in infants, children, or adults imaging plays an important role. A non-invasive and sensitive imaging modality is an efficient and cost-effective tool. Multidetector computed tomography (MDTC) with volumetric acquisition provides fast acquisition of high resolution images and multiplanar reconstruction. Both 2D and 3D imaging in mediastinal imaging help in surgical planning and assessing resectability of mediastinal lesions. MR imaging has many advantages over other modalities for detecting and identifying cystic, or fluid-filled mediastinal masses, because of its intrinsic high soft tissue contrast and direct multiplanar imaging capabilities. However, histological tissue analysis may be required to differentiate a cystic lesion from other cyst-like or low-attenuation lesions.

“…For instance, pericardial cysts located in the right cardiophrenic angle may be confused for a diaphragmatic hernia, whereas those at the left cardiophrenic angle may resemble a ventricular aneurysm. Historically prior to the development of imaging techniques it was recommended that these masses be resected as they could not be differentiated from solid masses 69,82,83 ; however, with the development of cross-sectional imaging these lesions may be properly identified as cysts non-invasively 18 (Fig 2). Current recommendations include non-invasive monitoring of the cyst by serial cCT or cMRI every 1 to 2 years.…”
