Cytological smears from 115 consecutive cases of stereotactic biopsies of @entity1504 were reviewed. Ninety-five lesions were solid and 20 cystic. Material from 90 solid and 13 @entity5409 was sent both for cytological and histological examination. In 66 of the solid lesions, the cytological diagnosis was confirmed by histology (five were benign lesions and 61 @entity5 : 56 primary @entity1313 , three @entity3 and two @entity706 ). In 24 cases with discrepant cytology and histology, the histology was inconclusive or insufficient in 14 cases, while cytology established the diagnosis of @entity816 grade II (seven cases), @entity3 (two cases), @entity5219 (one case) and benign (four cases). Necrosis of @entity5 type was observed cytologically in six @entity1 representing @entity463 (two cases), @entity816 (one case), @entity706 (one case) and normal brain (two cases) histologically. Three cases reported cytologically as benign were primary @entity1313 (two cases) and @entity5219 (one case). One smear of a @entity463 was insufficient for cytological diagnosis. @entity5409 were cytologically benign in 17 cases and malignant in three cases. Histology from the cyst wall confirmed the malignant diagnosis in three cases and showed @entity5 in six more cases, a benign process (two cases), changes induced by radiotherapy for @entity2758 (one case) and insufficient material (one case). In conclusion, cytology from solid @entity75 allows an accurate diagnosis and subtyping of @entity5 in a majority of cases, and can thus be used to choose type of therapy. In @entity1313 , however, examination of the cystic fluid, is often inconclusive and a biopsy from the cyst wall should be performed if there is clinical or radiological suspicion of @entity5 .
