Cervical Neurinoma associated with Hydrocephalus: Case Report

A 64-year-old woman with a 3-month history of gait disturbance and left leg numbness followed by headache, dementia and urinary incontinence. Head computed tomography (CT) revealed marked ventriculomegaly and magnetic resonance imaging with gadolinium contrast showed an enhanced mass at C2-3. Excision of neurinoma resulted in improvement of both gait and memory disturbance with no urinary incontinence. Follow up head CT demonstrated ventricular size became smaller without periventricular lucency. In this case, mechanical obstruction of the cerebrospinal fluid (CSF) pathway resulted in alteration of the spinal subarachnoid space function as a ‘buffer reservoir’ to cranial CSF circulation, and this can play a critical role, particularly in patients with normal CSF protein concentrations.
