A case of a giant adrenal cyst.

Giant adrenal cysts represent rare clinical entities that are usually discovered incidentally. Here, we describe a patient who presented with nonspecific upper abdominal left pain. Imaging studies revealed a huge left adrenal cyst. Routine laboratory tests and endocrine function tests were all normal. The patient underwent surgery, and the cyst was completely removed with total adrenalectomy. Histological examination revealed a benign epithelial adrenal cyst.The postoperative course was uneventful and the patient had no evidence of recurrence during a 3-year follow-up. We discuss the diagnosis and management of adrenal cysts.
