Abstract
We report a case of a surgically resected giant cystic pheochromocytoma. A 43-year-old female had a large abdominal mass. A computed tomography scan revealed a large, multicystic tumor with a maximum diameter of 26 cm occupying almost the entire abdominal cavity. The blood supply to the tumor suggested that its origin was the left adrenal grand ; subsequently, a diagnosis of pheochromocytoma was established based on urinalysis showing elevated catecholamine metabolite levels. A surgical resection of the left adrenal pheochromocytoma along with the left kidney was performed. The postoperative course was uneventful. The resected tumor mass weighed 5,900 g. On histopathology, the diagnosis of a well-differentiated pheochromocytoma with a relatively low risk of developing metastases was confirmed. To our knowledge, this is the first report of a patient surviving surgical resection of a giant pheochromocytoma weighing over 5,000 g.
