A giant
adrenal pseudocyst presenting with right hypochondralgia and fever: a case report. Abdominal ultrasonography revealed an 18 × 18 cm, heterogeneously hypo-echoic lesion in the right adrenal area with peripheral high-echoic rim.
A giant
adrenal pseudocyst presenting with right hypochondralgia and fever: a case report. An enhanced computed tomography of the abdomen revealed a giant homogeneous low density mass lesion in the right adrenal region. (A) A giant mass lesion was indented over the inferior aspect of the right lobe of the liver and a displaced inferior vena cava (arrowhead) with no abdominal lymphadenopathy. (B) The right kidney was also ventrally displaced.
A giant
adrenal pseudocyst presenting with right hypochondralgia and fever: a case report. Abdominal magnetic resonance imaging revealed a well-defined high intensity mass which appeared homogeneous intense in the T 1-weighted image (A) but heterogeneously intense in the T 2-weighted image (B).
Adrenal pseudocysts account for ~40% of adrenal cysts and are more likely than simple adrenal cysts to be symptomatic.
Pathology
Pseudocysts do not have an epithelial lining and typically arise after an episode of adrenal hemorrhage. There is an ~7% association with malignancy (e.g. from hemorrhage into a cystic adrenal neoplasm) .
Radiographic features
Adrenal pseudocysts appear as a simple cyst or may have a complicated appearance (i.e. septations, blood products, or a soft-tissue component).
CT
Calcification may be present . Usually, there is no enhancement post contrast.
Differential diagnosis
Imaging differential considerations include:
- cystic adrenal neoplasm: often has an enhancing component
