Osseous Hemangioma of the Inferior Turbinate: A Case Report and Review of Literature.

Intraosseous hemangiomas account for 1% of all primary bone tumors and most frequently affect the skull base and vertebrae. Rarely are they reported in the nasal cavity. We report a case of a 51-year-old male who complained of bilateral nasal obstruction. Nasal endoscopic examination showed a significantly enlarged right inferior turbinate with normal mucosal membranes. A CT scan revealed a well-defined heterogeneous mass with osseous borders originating from the bony lamella of the right inferior turbinate, with a honeycombed appearance. An en bloc transnasal endoscopic resection of the mass and turbinate was performed, revealing an intraosseous hemangioma of the inferior turbinate with a cavernous pattern. The postoperative period was uneventful with no recurrence. A literature review of intranasal intraosseous hemangiomas revealed 2 other cases resected endoscopically successfully.
