title: Developmental venous anomaly of the internal auditory canal in a child with unilateral sensorineural hearing loss--a rare association.
abstract: Developmental venous anomalies (DVAs) are extremely unusual in the cerebellopontine angle region and internal auditory canal, and constitute a rare etiology of unilateral sensorineural hearing loss (SNHL) in children. We report, to the best of our knowledge, one of the first documented cases of DVA as a probable cause of unilateral SNHL in a child. Our emphasis is on the radiological features.
