Abstract:
We report, with a review of literature, an unusual case of ossifying fibroma of temporal bone. A 34-year-old female with history of left craniectomy for hemifacial spasm visited our department in 1998 because of an incidentally found temporal bone mass. Magnetic resonance imaging showed a well-circumscribed, lobulated 3x3x3 cm sized tumor mass which was localized in the temporal bone but did not invade the middle and inner ear with high signal intensity at T2 weighted image. The patient did not have the spasm until 2000, when she manifested intermittent right otalgia. A computed tomography scan showed the 3x3x3 cm sized right temporal bone tumor with bony erosion including tegmen mastoid and partial bony destruction. After retroauricular incision, tumor and granulation tissue were removed through simple mastoidectomy. The permanent pathologic report confirmed the diagnosis of ossifying fibroma. The patient returned in August of 2004 with recurrent right otalgia that had been there for 3 months. A computed tomography scan showed lobulated, multiseptated, osteolytic, low density tumor which located in the upper portion of mastoid pyramidal base. She underwent a simple mastoidectomy with removal of the recurred ossifying fibroma with destruction in tegmen mastoid. Ossifying fibroma are rare lesions of the temporal bone. Because tumors progress and can become clinically massive, early complete resection is advised whenever feasible to prevent clinically evident recurrences and potentially life-threatening complication.
