ABSTRACT
Subependymomas are slowly growing glial tumors, corresponding to WHO grade I. Few descriptions of the cytologic features of this neoplasm are available. This study describes the cytologic features of three subependymomas, as well as their differential diagnosis based on cytology. Three men, aged 52, 56, and 63 years, presented with headache. Magnetic resonance imaging revealed a nodular intraventricular mass in all three patients. Intraoperative squash cytology specimens from the three intraventricular tumors showed nodular clusters with microcystic changes. Nuclei were round to oval in shape, but showed no evidence of severe nuclear atypia or mitoses. Histological examination showed features of subependymoma. Squash cytology findings, including nodular clusters, mild cellular atypia, microcystic changes, and mucoid material, are useful in the rapid intraoperative diagnosis of subependymoma.
