<B><I>Background</I>:</B> We report a rare case of ectopic orbital meningioma, in which intraoperative scraping cytology was very useful in diagnosis.<BR><B><I>Case</I>:</B> A 54-year-old man was admitted to our hospital after suffering from progressive left-sided ptosis 3 years. A mass lesion was palpated on left upper eyelid and computed tomography (CT) and magnetic resonance imaging (MRI) showed a 1.5cm mass lesion on the antero-superior aspect of the left levator palpebrae. The mass was resected when a frozen section showed an epithelial structure suspicious as invasion of a malignant epithelial tumor. Scraping cytology clearly showed clusters of benign cells with a whorl arrangement and intranuclear cytoplasmic intrusion (pseudoinclusion) suggestive of meningioma. Permanent histological specimens and immunohistochemical studies confirmed the diagnosis of meningotheliomatous and transitional meningioma.<BR><B><I>Conclusion</I>:</B> We treated a rare case of intraorbital ectopic meningioma in diagnosis by frozen section alone was not possible. Scraping cytology examination led us to correct the diagnosis and underscored the usefulness of intraoperative cytological examination.
