Review Case Reports
Iatrogenic cerebrospinal fluid leak and intracranial hypotension after gynecological surgery.
Perineural cysts are common lesions of the sacral spine. They have rarely been reported in a presacral location, leading to their misdiagnosis as a gynecological lesion. The authors report the second such case, in a patient undergoing fenestration of what was presumed to be a benign pelvic cyst, and the resultant high-flow CSF leak that occurred. ⋯ Appropriate imaging investigations should be performed to rule out a perineural cyst. The CSF leak that occurs from iatrogenic cyst fenestration may not respond to traditional first-line treatments for intracranial hypotension and may require early surgical intervention. The authors would recommend neurosurgical involvement prior to definitive treatment.
