A Case of spontaneous hemorrhagic pseudocyst of adrenal gland mimicking cystic pheochromocytoma / 대한내과학회지

ABSTRACT

Cysts of the adrenal glands are uncommon and present difficult problems in differential diagnosis. In autopsy studies, the incidence of adrenal cysts is ranges from 0.064% to 0.18%. Recently, we have experienced a 22-year-old female patient with spontaneous hemorrhagic pseudocyst of adrenal gland without known cause, presenting symptoms of nausea, epigastric discomfort and intermittent pain of right upper abdomen. In clinical presentation, abdominal ultrasonogram and computerized tomogram suggest cystic degeneration of malignant pheochromocytoma, but screening hormonal evaluation was normal. Selective adrenal venous sampling, adrenal scintigram and pathologic examination were not compatible with the functioning adrenal cortical or medullary adenoma/carcinoma, the mass results in spantaneous hemorrhagic necrosis and cystic degeneratio#n of adrenal gland. The authors reported a case of spontaneous hemorrhagic pseudocyst of adrenal gland, which was successfully resected by laparoscopic excision with reviews of the literatures.
