腎血管性高血圧症 - 後腹膜類皮嚢胞による1例 -

Abstract

A 9-year-old boy had noticed sudden onset of head-ache and vomiting one month prior to the first visit when hypertension (190/100) was detected. Examinations such as IVP, renal arteriography, renogram led to diagnosis of renovascular hypertension due to compression of the left renal artery by a retroperitoneal tumor. Retroperitoneal tumor and the left kidney were removed surgically. On the third postoperative day the patient returned to normal blood pressure. No episode of hypertension was experienced for two years after surgery. Removed tumor was dermoid cyst, and the histological study of the kidney showed increased juxtaglomerular apparatus cells. This was the first reported case of renovascular hypertension caused by retroperitoneal dermoid cyst.
