Abstract

Inflammatory pseudotumor of the liver is a rare entity; fewer than 50 cases have been reported in the world literature. Its appearance on both computerized tomography (CT) and ultrasound have been previously described. To our knowledge, this is the first report of its appearance on magnetic resonance imaging (MRI). The lesion demonstrated increased signal intensity on T-1 and T-2 spin-echo and inversion recovery (STIR) sequences in relationship to normal liver. The signal characteristics, however, were nonspecific and diagnosis required biopsy confirmation. There was spontaneous resolution with conservative management, and this was documented on follow-up CT and MRI.

摘要

肝脏炎性假瘤是一种罕见的疾病；世界文献中报道的病例少于50例。其在计算机断层扫描（CT）和超声上的表现此前已有描述。据我们所知，这是其在磁共振成像（MRI）上表现的首次报道。该病变在T-1、T-2自旋回波和反转恢复（STIR）序列上相对于正常肝脏表现为信号强度增加。然而，信号特征不具有特异性，诊断需要活检证实。通过保守治疗病变自行消退，后续的CT和MRI检查记录了这一情况。
