自潰した後腹膜腔膿瘍の1例—特に後腹膜腔膿瘍におけるCT所見について

RETROPERITONEAL SPACE ABSCESS WITH SPONTANEOUS DRAINAGE OUT OF THE FLANK: REPORT OF A CASE. COMPUTED TOMOGRAPHY OF THE RETROPERITONEAL SPACE ABSCESS

緒言

　後腹膜腔膿瘍は早期診断が困難であり，治療に難渋する外科的感染症の一つである。今回われわれは，診断確定前に側腹壁に穿孔し自潰排膿した後腹膜腔膿瘍の1例を経験したのでここに報告し，後腹膜腔膿瘍におけるCT所見とその診断価値について述べる。

A 59-year-old female, who had an episode of fever and easy-fatiguability for a month prior to her visit to our clinic, was refered for evaluation of left flank pain and tumor.

As retroperitoneal space abscess or left renal tumor was suspected by RP, renal scintigram and CT, angiography was scheduled, but spontaneous abscess drainage out of the left flank was seen on May 29, 1982. Immediately after spontaneous drainage the retroperitoneal space was washed out and drained under local anesthesia.
