Overview
If left untreated, patients with meningioma may progress to develop morning headache, focal neurological deficit, and altered mental status. Common complications of meningioma include increased intracranial pressure, cranial nerve palsies, and hydrocephalus. Prognosis is generally good, and the survival rate of patients with meningioma mainly depends on the grade and location of the tumor.[1][2]
Natural History
- Most patients with meningioma are asymptomatic. If left untreated, patients with meningioma may progress to develop morning headache, focal neurological deficit, and altered mental status.[1]
Complications
- Common complications of meningioma include:[1]
Prognosis
- Depending on the histological grade of the meningioma at the time of diagnosis, the prognosis may vary. However, the prognosis is generally regarded as good.[1]
- Grade 1 meningioma is associated with a median survival of approximately 10 years.[2]
- Grade 3 meningioma is associated with a median survival of approximately 2.7 years.
- The table below lists common prognostic factors for meningioma:[3]
| Prognostic Factor | Description |
| Age | Older age is associated with a worse prognosis |
| Anatomical location | Meningioma located at the base of the skull is associated with a poor prognosis due to difficult surgical resection. |
| Labeling index using MIB-1 test | A greater MIB-1 labeling index is associated with a worse prognosis. |
| Histological grade | A grade 3 anaplastic meningioma is associated with the worst prognosis. |
| Functional neurological status | Low score on the Karnofsky Performance Scale is associated with a worse prognosis. |
| Sex hormone receptor | Meningiomas that lack progesterone receptors are associated with a worse prognosis due to a higher recurrence rate following surgery.[2] |
