Clinical History:

A 60-year-old man with a 1-year history of left upper abdominal pain and distension

Findings:

Figure 1: Non-contrast CT revealed a giant cystic lesion over the left suprarenal region measuring 13 x 12 x 10 cm.

Diagnosis:

Adrenal pseudocyst

Discussion:

Adrenal cysts are rare and mostly silent clinically.Symptoms are usually related to the size and local pressure effect of the cysts.(1)An autopsy study reported a 0.06% incidence of adrenal cysts in the population.(2)Adrenal cysts have been reported in patients of all ages.Since up to 7% of adrenal cysts are malignant, a careful hormonal, morpho-functional and instrumental evaluation is mandatory.Improvement in diagnostic technology now makes it possible to identify asymptomatic or non-functioning adrenal tumors, including adrenal cysts.(3)
Radiological and clinical features of the tumor are nonspecific and histopathological examination is essential to establish definitive diagnosis.Treatment of adrenal cysts depends on the underlying pathology, size of the cyst, associated symptoms and the occurrence of complications(4)
