Submitral Aneurysm Presenting as Pulsating Epigastric Mass-Diagnostic and Surgical Considerations.

We report the case of a ten-year-old female child presenting with SMA with anteroinferior extension, differing from the more typical posterior and lateral extension. Successful surgical management is described.
