[Brain abscess as a complication of ear malignancy: a case report].
Ear infection is the most common cause of brain abscess. A suppurative process in the ear has access to the central nervous system by direct extension or through preformed pathways, either developmental, traumatic or pathologic, or by retrograde spread along the thromobophlebitic vein. Squamous cell carcinoma of middle ear or mastoid cavity is a rare disease and often associated with chronic otitis or chronic draining ear. Ear malignancy easily produces the destruction of temporal bone which may serve as a route for coexistent infection spreading into the brain. This paper reports a case of brain abscess occurring in a patient with temporal bone cancer. To the best of our knowledge, no more than three similar cases have been reported in the literature. The authors suggest that if an otogenic brain abscess is concomitant with infection and granulomatous mass in the ear, biopsy should be performed to rule out malignancy.
