Abstract

Intraosseous hemangioma is a rare benign vascular tumor, uncommon in the maxilla or mandible. Its variable radiograph­ic appearance often complicates diagnosis, as it can mimic other conditions like periapical cysts. This report discusses a 26-year-old female misdiagnosed with a cyst, later revealed to have a vascular lesion after massive bleeding during surgery. Emergency embolization successfully controlled the hemorrhage, allowing safe resection. The case highlights the critical need for accurate differential diagnosis and preoperative planning, including embolization, to manage such lesions and avoid life-threatening complications.
