Intraosseous hemangioma as a rare differential diagnosis of intranasal bony tumor.

Intraosseous hemangioma is a benign vascular tumor of the bone. The most common site of this tumor is the vertebral body, followed by calvarial bones. Intraosseous hemangioma of the nasal cavity is extremely rare. This lesion had en bloc been resected through the endoscopic approach without preoperative embolization, significant intraoperative bleeding, and postoperative events. We report a rare case of intraosseous hemangioma of the nasal cavity with distinctive radiologic findings. Clinicians should be well familiar with the radiologic findings and clinical features of this tumor, which would be helpful in making a correct diagnosis and management plan.
