18歳男,血尿,陰嚢部の違和感を主訴に発見され,左側腎無形成を伴っていた.術前血清CA19-9が高値を示したが,このような症例の記載はないA case of pathological dilation of seminal vesicle is presented. A 18-year-old male was admitted to our hospital with the complaints of gross hematuria and discomfort of the scrotum. IVP and abdominal CT scan revealed the left aplastic kidney, and ultrasound, vesiculography, and pelvic CT scan revealed markedly dilated bilateral seminal vesicles without filling defects. The level of serum CA19-9 was 390 u/ml, which was extremely high. After resection of dilated seminal vesicles, it returned to the normal range (37 u/ml). Sixty six cases of pathological dilation of seminal vesicle were collected from the Japanese literature. No cases showing a high level of serum CA19-9 have been reported in Japan.
