title: A rare case of white pearls in brainstem.
abstract: Intrinsic brainstem epidermoid is extremely rare, and only 14 cases have been reported. Authors report a classic case of brainstem epidermoid in a 14-year-old male child presenting with symptoms of brainstem involvement. The child underwent a successful surgical excision. The lesion was intrinsic and caused diagnostic dilemma based on conventional radiological images. Based on our experience in this case and a thorough review of literature, we are of the opinion that diffusion-weighted images are very important in establishing the diagnosis. Such lesions are challenging and attempt to remove adherent tumor capsule may produce additional neurological deficits.
