Meningioma followed up for radiological findings before and after radiosurgery: case report.
The present paper reports on serial image changes before and after radiosurgery regarding a falx meningioma incidentally discovered in a 79-year-old female. The tumor doubling time during the 3-year observation period before radiosurgery was 469 days. Following radiosurgery using a gamma knife, tumour volume temporarily increased, but then reduced to 55% in 22 months. No symptoms or signs are observable at present, when the patient is 84 years old. These findings suggest that in treating elderly patients with meningioma diagnosed by imaging, radiosurgery should be the first method considered. Also presented are changes in image findings over time.
