A case of cystic meningioma in a 9-year old girl is reported. The init
ial clinical symptom was focal epilepsy, and this was followed by prog
ressive hemiparesis. CT of the brain detected a calcified tumour to wh
ich two cysts were attached. The tumour was strongly enhanced by the c
ontrast medium. Histology confirmed that the lesion was a meningioma o
f the psammous type. A review of the literature showed that this is a
rare tumour the pathogenesis of which can be explained in various ways
. Nautal's classification into 4 types is the most widely adopted. The
diagnosis has been made in only 38 % of the 166 cases published.
