## Contribution

This case report emphasizes the importance of considering posterior epistaxis as a cause of unexplained upper GI bleeding.

- Endovascular intervention successfully treated the dilated sphenopalatine artery.
- Gastroenterologists should consider nasal endoscopy for patients with unexplained UGIB.

## Abstract

A 21‐year‐old Palestinian woman experienced recurrent hematemesis and melena over 7 months, requiring multiple hospital admissions and blood transfusions. Despite extensive investigations, the bleeding source remained undetermined until a posterior nasal bleed was suspected. Flexible rhinoscopy revealed a dilated sphenopalatine artery, and she was successfully treated with endovascular intervention. It is important for the Gastroenterologists to consider nasal endoscopy for patients with unexplained UGIB.
