Abstract

Meningioma is one of the most common intracranial tumor in adult. The tumor, however, occurs very rarely outside the central neuraxis, such as orbit, nasal cavity of parotid area. We report a case of extracranial meningioma in the parotid area. A 38-year-old man was presented with a round mass in the left parotid area. Magnetic resonance imaging revealed a round mass attached to anterior pole of the left parotid. The mass was easily separated from facial nerve. Microscopically, the mass was composed of ovoid or spindle cells. The tumor cells tended to show bundle formation, lobular arrangement and occasionally whorling appearance. This case is important at the means that meningioma should be included in differential diagnosis of mass in the parotid area.
