Abstract

This case report describes a 67-year-old male who presented with right flank pain and unintentional weight loss, subsequently diagnosed with spontaneous portal vein thrombosis (PVT). Despite the absence of cirrhosis, malignancy, or identifiable prothrombotic conditions, imaging and anticoagulation therapy played a critical role in managing his condition. This report underscores the importance of early diagnosis, individualized anticoagulation therapy, and thorough investigation of underlying causes in the management of PVT. © 2026 Tehran University of Medical Sciences.
