A chronic encapsulated expanding hematoma that developed 20 years after gamma knife surgery for a cerebral epilepsy

Abstract

Background:We report a patient diagnosed with epilepsy 20 years ago who developed a chronic encapsulated expanding hematoma after gamma knife surgery. Case presentation:A 49-year-old middle-aged female was admitted to our department due to headaches accompanied by left-sided limb weakness for 2 months. Cranial computed tomography (CT) and magnetic resonance imaging (MRI) scans revealed a giant cystic-solid mass in the right frontal-temporal lobe, accompanied by compression and edema of the surrounding brain parenchyma. After completion of relevant preoperative examinations upon admission, she underwent microsurgical evacuation of the chronic encapsulated expanding intracerebral hematoma. Postoperatively, the patient improved and recovered well. Conclusion:Chronic encapsulated expanding hematoma is a rare complication after gamma knife surgery therapy. It's essential for individuals experiencing symptoms or complications related to a hematoma to seek medical attention for proper evaluation and management.
