Overview

Presentation of a case of a „central type“ neurofibromatosis in a 56-year old woman, clinicallydiagnosed erroneously as multiple sclerosis with a 20 years long course. Disturbances of hearing,walking, sight, sensitivity, incontinentia, intracranial hypertension and headache representedthe main symptoms. More than 120 intracranial and tens of intraspinal meningiomas representedthe leading postmortem finding. In a lesser frequency spinal plexiform neurofibromas andschwannomas were also found. The death was attributed to aspiration purulent bronchopneumo-nia. Various types of meningioma were seen microscopically, including secretory type and a typewith amyloid. Immunostaining was positive with S-100 protein and EMA. Negative expression wasfound with vimentin, CEA, smooth muscle actin, estrogen and progesterone receptors, amyloidA and cytokeratins. With regard to the presence or absence of key morphological features thepresented case was placed according to Sobol et al. (29) into the seventh category of neurofibro-matosis (NF7).
