Surgical approach is a routine procedure of bleeding c ontrol. However, bleeding control using angiography and emboliz a-tion can also be an excellent method. We experienced pseudoaneu rysm of the inferior alveolar artery occurring after surgical curettage of cystic lesion. The 33-year-old man who underwent s urgical curettage of keratocystic odontogenic tumor was present ed with severe bleeding in the right mandible ramal inner surface 14 days after the surgical curettage. After hemostasis with vaseline gauze packing and pressure, bleeding temporarily stopp ed. However, bleeding started after 14 days and soon it has been continued. Finally, the patient was diagnosed as pseudoane urysm of the inferior alveolar artery from the enhanced-compute d tomography images, and angiographic embolization was performed successfully. We report a rare case of pseudoaneurysm of the inferior alveolar artery after benign tumor curettage and review of the previewer’s literature.Key words:False aneurysm, Inferior alveolar artery, Angiography, Therapeu tic embolization, Keratocystic odontogenic tumor
