summary
A 51-year-old woman suffering an epileptic seizure came to the emergency unit. A ct scan showed a mass lesion in the right frontal lobe. The psychiatric examination indicated a frontal syndrome with severe cognitive impairment. A stereotactical biopsy was carried out. Histopathology produced an unusual diagnosis, namely an intracerebral amyloidoma. By reviewing the literature on intracerebral amyloidoma we were able to compare the psychiatric symptoms of published cases with those of this case.
