Abstract

A 52-year-old man was admitted with a brain abscess in the left basal ganglia. He had a paradoxical brain embolic mechanism owing to a pulmonary arteriovenous fistula (PAVF) and was diagnosed as having a right-to-left shunt by transesophageal echocardiography (TEE) and transcranial color Doppler (TCD) with saline contrast medium. We determined that the brain abscess was caused by the PAVFs without Rendu-Osler-Weber disease. TEE and TCD with saline contrast medium were very useful for identifying the presence of the right-to-left shunt that caused the brain abscess.

摘要

一名52岁男性因左侧基底节区脑脓肿入院。由于存在肺动静脉瘘（PAVF），他具有反常脑栓塞机制，经食管超声心动图（TEE）和经颅彩色多普勒（TCD）注射生理盐水造影剂检查诊断为存在右向左分流。我们确定该脑脓肿是由无遗传性出血性毛细血管扩张症的PAVF引起的。TEE和注射生理盐水造影剂的TCD对于识别导致脑脓肿的右向左分流的存在非常有用。
