Spinal adhesive arachnoiditis after spinal anesthesia complicated by communicating hydrocephalus - A case report.

BACKGROUND

Adhesive arachnoiditis (AA) is a debilitating condition characterized by chronic inflammation of the arachnoid membrane, leading to the formation of intrathecal scars and dural adhesions. The etiology of AA is multifactorial, including factors such as infections, trauma, and iatrogenic damage. We present a case of a female patient who developed communicating hydrocephalus after spinal anesthesia complicated by severe AA.

CASE DESCRIPTION

A 33-year-old female underwent a cesarean section with epidural anesthesia. Five hours postoperatively, she experienced transient difficulty standing, which was resolved with assistance. Weeks later, she developed a severe holocephalic headache accompanied by nausea, vomiting, photophobia, and phonophobia. Imaging revealed hydrocephalus and pronounced AA. Lumbar puncture provided symptomatic improvement. The patient underwent ventriculoperitoneal shunt insertion, resulting in further symptom improvement and successful shunt function.

CONCLUSION

AA is a challenging condition associated with inflammation and scarring of the arachnoid membrane. The development of hydrocephalus following epidural anesthesia, in this case, highlights a rare manifestation of arachnoiditis. Further research and documentation are needed to understand better the underlying mechanisms and risk factors contributing to hydrocephalus in the context of AA following epidural anesthesia.
