Management of Fourth Ventricle Arachnoid Cyst Using Open Suboccipital Craniectomy and Marsupialisation at a Tertiary Hospital – Case Report
Keywords:
fourth ventricle arachnoid cyst, suboccipital craniectomy, fenestration and marsupilisationAbstract
Background: Fourth ventricular arachnoid cysts are rare, often presenting with symptoms of raised intracranial pressure or brainstem compression. Case Presentation: A 41-year-old male with a six-month history of headaches and difficulty walking was diagnosed with a fourth ventricular arachnoid cyst causing obstructive hydrocephalus. He underwent suboccipital craniotomy with marsupialisation, leading to successful decompression and symptom resolution. Conclusion: Suboccipital craniotomy with marsupialisation is an effective and safe approach for managing symptomatic fourth ventricular arachnoid cysts, ensuring long-term relief and preventing recurrence.
