ホルモンの異常高値を示した副腎嚢腫の1例

A CASE OF ADRENAL CYST WITH HORMONAL ABNORMALITY

緒言

　副腎嚢腫は一般に内分泌学的非活性であるため臨床症状を示すことが少なく，稀な疾患とされてきた。しかし，超音波断層法やCTスキャンなどの診断技術の向上により，今後は偶然発見される症例が増えていくものと予想される。今回われわれは人間ドックを受診中，超音波断層により発見された副腎嚢腫の1例を経験したので報告する。

A 42-year-old male was referred to us for detailed examination of left renal cyst. But CT scan revealed a left adrenal cyst. Urine 17-KS, 17-OHCS and VMA and serum cortisol were elevated. An adrenal cyst with normal adrenal tissues was removed through the 10th intercostal space incision. The surgical specimen was 8.0×6.5×2.8cm, 134g and contained 105ml of bloody fluid. Histologically in the cyst wall fibrous connective tissue with a few endothelial cell lining was inspected. After the operation urine 17-KS, 17-OHCS and VMA were lowered to normal.
