Abstract

A case with primary amyloidosis of the liver and spleen is presented. In the liver, ultrasonography showed heterogeneous echogenicity. Portal phase CT showed heterogeneous enhancement, and delayed phase CT showed delayed enhancement with focal hypoattenuating areas. Bone scintigraphy showed diffuse accumulation. In the spleen, arterial phase CT showed the lack of parenchymal enhancement, and T2-weighted MR imaging showed decreased signal intensity. The combination of imaging findings of the liver and spleen was suggestive of amyloidosis.

摘要

本文报告一例肝脾原发性淀粉样变性病例。肝脏超声检查显示回声不均匀。门静脉期CT显示强化不均匀，延迟期CT显示延迟强化伴局灶性低密度区。骨闪烁显像显示弥漫性放射性浓聚。脾脏动脉期CT显示实质无强化，T2加权磁共振成像显示信号强度降低。肝脏和脾脏的影像学表现综合提示淀粉样变性。
