Background:
Amyloidoma (tumoral amyloidosis) is the rarest form of central nervous system (CNS) amyloidosis.
Case:
A 51-year-old woman presented with recurrent right-sided otitis media and hearing loss. Computed tomography and magnetic resonance imaging revealed a mass in the right temporal lobe. Cytologic findings at the time of stereotactic biopsy for suspected glioma were compatible with amyloidoma. Subsequent histologic and electron microscopic findings confirmed the diagnosis of amyloidoma. Auxiliary testing ruled out systemic amyloidosis and plasma cell dyscrasia.
Conclusion:
To our knowledge, this is the first report on the cytologic findings in a case of CNS amyloidoma.
