Aneurysms of the middle colic arterial branches are extremely rare, the main manifestation occurs due to the rupture and intraabdominal bleeding making death possible in up to 70% of cases. Herein, we report a case of a male patient, who is 50 years old and displays intermittent, recurrent, and self-limited episodes of a digestive hemorrhage that has been symptomatic during the course of a three-month investigation. After an extensive investigation, the patient was submitted to angiography detecting a pseudoaneurysm in the middle colic branch, being treated by embolization using micro-coils. Intermittent digestive hemorrhages from an obscure source can represent a diagnostic challenge, due to the high degree of clinical suspicion for performing the correct differential diagnosis. Arteriography must not be delayed whenever a pseudoaneurysm with active bleeding is suspected, as this exam is selected for diagnosis and the preferred method for conclusive treatment.
