Summary
Hemorrhage can occur in meningiomas years after gamma knife surgery. This case highlights a rare delayed complication, emphasizing the need for long-term patient monitoring following radiosurgery.
Area of Science:
- Neurosurgery
- Radiation Oncology
- Neuropathology
Background:
- Meningiomas are primary tumors of the central nervous system.
- Gamma knife surgery (GKS) is a common treatment for meningiomas.
- Delayed complications after GKS are infrequently reported.
Observation:
- A patient with a tentorial hiatus meningioma treated with GKS developed apoplectic symptoms three years post-treatment.
- Magnetic resonance imaging (MRI) revealed tumor swelling and increased peritumoral edema.
- Computed tomography (CT) confirmed a peritumoral hemorrhage.
Findings:
- Biopsy of the meningioma showed a transitional type with vasculopathy and necrosis.
- The patient experienced right hemiparesis and a visual defect post-craniotomy.
- This indicates a rare delayed hemorrhagic complication following GKS for meningioma.
Implications:
- This case underscores the importance of long-term surveillance for patients undergoing GKS for meningiomas.
- Delayed hemorrhage may be a rare but significant complication of GKS.
- Further research into the mechanisms of delayed radiation-induced complications is warranted.
