Background:

Angiodysplasia is a prevalent cause of lower gastrointestinal bleeding, particularly in elderly patients.
Lesions are typically found in the cecum or ascending colon.
Appendiceal angiodysplasia represents an exceptionally rare presentation.

Observation:

A 76-year-old woman presented with severe, recurrent rectal bleeding.
Diagnostic imaging identified bleeding originating from an angiodysplasia within the appendix.
The source was traced to the appendicular artery.

Findings:

The patient underwent an appendectomy for the bleeding source.
Postoperative follow-up confirmed the cessation of anal bleeding.
