Case Discussion

Incidental finding of a large 4.8 cm intra-hepatic portal vein aneurysm in a 90 year old male being investigated for PR bleeding.

The patient was reviewed by the vascular surgery team, however given the patient's advanced age and the asymptomatic nature of the aneurysm, conservative management was recommended.
