Sarcoidosis is a multisystemic inflammatory disease of unknown origin characterized by the formation of noncaseating granulomas and accumulation of inflammatory cells. Sarcoidosis most commonly affects the lungs and lymphoid system. However, the liver can also be involved in 50%-65% of cases. On magnetic resonance imaging, sarcoidosis lesions usually present as hypointense lesions on all sequences. However, we present a rare case of nodular liver sarcoidosis presenting with T2 hyperintense lesions. In addition, while most cases of hepatic nodular sarcoidosis present with multiple small hepatic nodules, liver masses of our case are larger than usual. Moreover, this case suggested that when intact vascular structures penetrating liver nodular lesions are observed as in the current case, liver sarcoidosis can be included in a list of differential diagnosis.
结节病是一种病因不明的多系统炎症性疾病,其特征是非干酪样肉芽肿的形成和炎症细胞的积聚。结节病最常累及肺部和淋巴系统。然而,50%-65%的病例肝脏也会受累。在磁共振成像上,结节病病变通常在所有序列上均表现为低信号病变。然而,我们报告了一例罕见的结节性肝结节病,其表现为T2高信号病变。此外,虽然大多数肝结节性结节病病例表现为多个小肝结节,但我们病例中的肝脏肿块比通常情况更大。而且,该病例表明,如本例中观察到有完整的血管结构穿透肝结节病变时,肝结节病可列入鉴别诊断清单。
