Intraparenchymal hemorrhage after surgical decompression of an epencephalon arachnoid cyst: A case report

BACKGROUND: This study reports the clinical presentation of intraparenchymal hemorrhage as a rare complication after surgical decompression of an intracranial epencephalon arachnoid cyst (IEAC) at the posterior cranial fossa. CASE SUMMARY: The clinical information of a patient with an IEAC was reported, and the related literature was reviewed. A female patient with nausea presented to our hospital. Computed tomography demonstrated an IEAC located at the posterior cranial fossa, which was large and required surgical intervention. After operation, postoperative intraparenchymal hemorrhage was detected. She had a good recovery with conservative treatment 1 mo later. CONCLUSION: Though postoperative intraparenchymal hemorrhage is rare after surgical decompression of an IEAC, more attention should be paid to such a complication.
