Abstract

A 60-years-old patient with a history of a rectal adenocarcinoma treated by chemotherapy, has developed a paraneoplastic portal thrombosis, known for a few months. The patient is referred to us for a thoraco-abdomino-pelvic computed tomography scan as part of his usual follow-up. it was noted a replacement of the portal vein by multiple serpiginous vascular structures compatible with a portal cavernoma, associated with a hypertrophy of the segment IV (FIG. 1).
