Abstract

A "halo sign" has been described in patients with Crohn disease, ulcerative colitis, radiation enteritis, ischemic colitis, and pseudomembranous colitis. This sign is characterized by an inner ring of low CT attenuation surrounded by a higher attenuation outer ring. We present a patient with primary intestinal lymphangiectasia in whom CT demonstrated a halo sign correlated with mucosal biopsy.

摘要

“晕征”已在克罗恩病、溃疡性结肠炎、放射性肠炎、缺血性结肠炎和伪膜性结肠炎患者中被描述。该征象的特征是CT低密度衰减的内环被较高密度衰减的外环所包围。我们报告一例原发性肠淋巴管扩张症患者，其CT显示晕征与黏膜活检相关。
