A case report of cerebrospinal fluid rhinorrhea through the ipsilateral nostril post vestibular schwannoma surgery through retrosigmoid suboccipital approach

Vestibular schwannomas are benign tumors of the cerebellopontine angle commonly managed by microsurgical excision. Cerebrospinal fluid (CSF) leak is a known post-operative complication; however, delayed CSF rhinorrhea through the ipsilateral nostril is a rare presentation. We report a case of a 45-year-old male who underwent right retrosigmoid suboccipital craniotomy and tumor excision for vestibular schwannoma. The post-operative period was initially uneventful, but the patient later presented
