Case report: unusual appearance of a giant adrenal pseudocyst.

Adrenal pseudocysts are uncommon lesions which usually present with abdominal discomfort and swelling due to their large size. The computed tomographic appearances typically demonstrate a smooth thin-walled low attenuation mass with peripheral curvilinear calcification. This case demonstrates the unusual appearances of a pseudocyst with multiple central punctate calcifications as a result of repeated haemorrhage. The radiological appearance of this complex mass mimicked an hydatid cyst. The increase in size of the pseudocyst is demonstrated over a 4 year period.
