Abstract

Pancreatic sarcoidosis is a rare entity, and few reports in the literature describe the CT aspects of the disease. We report the MR features of a pathologically-confirmed case of pancreatic sarcoidosis, which presented as multiple pancreatic masses with low signal intensity on T1-weighted images, mild high signal intensity on T2-weighted images, and decreased enhancement compared to the normal pancreas after administration of gadolinium. Pancreatic sarcoidosis should therefore be included in the differential diagnosis of multiple pancreatic masses with these MRI features.

摘要

胰腺结节病是一种罕见的疾病,文献中很少有报道描述该疾病的CT表现。我们报告一例经病理证实的胰腺结节病的磁共振成像(MR)特征,其表现为胰腺多发肿块,在T1加权像上呈低信号强度,在T2加权像上呈轻度高信号强度,注射钆剂后与正常胰腺相比强化减弱。因此,具有这些MRI特征的胰腺多发肿块的鉴别诊断应包括胰腺结节病。
