Recurrent cystic meningioma.
A case of a cystic meningioma recurring in its cystic form, two years after the initial removal, is presented. Regarded as a true cystic meningioma, the possible aetiology of the cyst formation is suggested. As the cyst wall itself may give rise to tumour cells, it is recommended that the initial operation should be directed at total removal of the tumour mass and cyst wall, thus reducing the possibility of a tumour recurrence. A CT finding of a hypodense lesion in a patient, operated on previously for a cystic meningioma suggests a recurrence of the tumour. However, other non-neoplastic changes should be considered.
