[Episodic bleeding events due to arteriovenous malformation (AVM) in the region of the distal ileum in a young male patient]. / Episodenhafte Blutungsereignisse bei arteriovenöser Malformation (AVM) im Bereich des distalen Ileums beim jungen Patienten.

We report the case of a 32-year-old male patient who presented with episodic, self-limiting gastrointestinal bleeding events. After both esophagogastroduodenoscopy (EGD) and colonoscopy remained unremarkable, capsule endoscopy revealed an unexplained mucosal lesion that presented as an ulcerated process on spiral enteroscopy. Appropriate enteroscopic ink marking was followed by surgical partial resection of the distal ileum, with histopathology revealing evidence of an arteriovenous malformation (AVM). This case emphasizes the importance of deep enteroscopy both in the diagnosis and to facilitate therapeutic resection in rare gastrointestinal bleeding events affecting young people.
