Endolymphatic sac tumor (ELST) is a rare neoplasm which is seldom evaluated by cytopathology. We report the clinicopathologic course and cytologic cerebrospinal fluid (CSF) findings in a 58‐year‐old patient with brainstem lesions who originally presented with vertigo but progressed to having left 7th, 8th, 9th, and 10th cranial nerve palsies, right‐sided weakness, and occipital headaches. Cytospin of the CSF revealed large epithelioid cells similar to cells seen in a surgical resection of a brain mass three months previously. Review of the surgical specimen revealed a well‐differentiated glandular and papillary neoplasm, most consistent with an endolymphatic sac tumor. Diagn.
