Third ventricle arachnoid cyst presenting with acute hydrocephalus: A case report and review of the literature

Özet

We present a 57-year-old male admitted to emergency depart-ment with acute loss of consciousness and diagnosed with third ventricular arachnoid cyst. Transcallosal cyst resection was per-formed following an emergency ventriculostomy. Postoperative imaging revealed gross-total cyst excision and a moderate decre-ase in hydrocephalus. However, the patient improved only after a subsequent ventriculoperitoneal shunting. This time, however, a subdural hematoma occurred under the craniotomy incision. In conclusion, surgical approach for the treatment of arachnoid cysts of the third ventricle should be selected carefully. Cyst exci-sion via open craniotomy may require subsequent shunting and can cause serious complications such as subdural hematoma.
