Chronic abdominal pain and Budd-Chiari syndrome: A relentless quest for an underlying neoplastic etiology.

In this article, we report on a 62-year-old non-cirrhotic male presenting to the emergency department (ED) with chronic abdominal pain, anorexia, and weight loss. Upon initial presentation, physical exam was unremarkable, other than for sarcopenia and splenomegaly. Initial imaging studies revealed a large thrombosis from the iliac vein to the right atrium of the heart. Following discharge, the patient re-consulted to the ED four months later and was re-admitted in renal failure and ascites. The diagnosis of Budd-Chiari syndrome (BCS) was established. Positive immunohistochemistry confirmed a neoplastic ideology of epithelial nature. This case offers a unique perspective on the clinical presentation of secondary BCS, necessitating a consideration in the differential diagnosis of a para-vascular cause. In this case, chronic abdominal pain, often overlooked, may necessitate further workup to establish a clinical diagnosis.
