Abstract

The authors describe the case of a 37-year-old female with a symptomatic epithelial cyst in the cerebellopontine angle, which is extremely rare. The cyst caused trigeminal neuralgia, which completely disappeared following its removal. The histological diagnosis was choroidal epithelial fluid-filled cyst. The wall of the cyst consisted of a single layer of epithelial cells with microvilli and a basement membrane.
