Endolymphatic sac tumor is rare, locally aggressive and non-metastasizing neoplasm arising from the endolymphatic sac of the petrous portion of the temporal bone. Most occur in adult and present with ipsilateral hearing loss. They can be sporadic or associated with Von-Hippel-Lindau disease. Patient with endolymphatic sac tumor should be screened for VHL disease. We report a case of 52-year-old female with dizziness and headache. Histopathology was consistent with typical features of endolymphatic sac tumor. This was confirmed by cytokeratin and EMA positivity and TTF-1 negativity. This case is presented for its rarity with only few cases reported.
