Portal venous aneurysm demonstrated by magnetic resonance imaging.
Portal venous aneurysm is an unusual vascular abnormality. We present this entity with magnetic resonance imaging (MRI) findings showing characteristic flow abnormality in two patients. Ultrasound examination revealed hyperechoic lobulated masses in the portal vein and the duplex Doppler study confirmed the venous flow patterns of low resistance within the lesion. The literature regarding this entity and the potential role of MRI are briefly discussed.
