Aggressive middle turbinate osteoblastoma with intracranial extension: a case report

Osteoblastoma is an uncommon benign bone tumor that accounts for 1 percent of all primary bone tumors. About 30 to 40 percent of all osteoblastoma cases involve the spine. Osteoblastoma involving the nasal cavity is rare, with only 11 reported cases in the English-language literature, while only fou...

Description
Summary:Osteoblastoma is an uncommon benign bone tumor that accounts for 1 percent of all primary bone tumors. About 30 to 40 percent of all osteoblastoma cases involve the spine. Osteoblastoma involving the nasal cavity is rare, with only 11 reported cases in the English-language literature, while only four cases of turbinate osteoblastoma have been described. We report an unusual case of middle turbinate osteoblastoma associated with right-sided nasal obstruction and severe headache in a 14-year-old Caucasian girl. The tumor involved the right middle turbinate, complete anterior and incomplete posterior ethmoidal cells, and the frontal sinus ostium. Cribriform lamina was, in the most part, consumed by the tumor growth, while the skull base was mostly of normal bone structure. To the best of our knowledge, this is the first case of middle turbinate osteoblastoma with intracranial spread. Surgical treatment is the only therapeutic option for osteoblastoma.
