摘要

Meningiomas are benign tumors derived from arachnoid cells. Most commonly they arise within the cranial cavity, but they may arise extracranially in various anatomic sites. We present four cases of orbital meningiomas diagnosed on fine-needle aspiration cytology (FNAC) and confirmed on histopathology. All the cases are presented with orbital mass. FNAC smears showed classical whorling and syncytial pattern of cells, withround to oval nucleus, inconspicuous nucleoli and one eachcase showed intranuclear inclusion and psammoma bodies. FNAC diagnosis of such lesions is difficult, because cytological features may mimic other soft tissue lesions located in orbital region. Awareness of this entity and its cytological appearance is important to allow correct diagnosis. Diagn. Cytopathol. 2012.
