title: Pseudoneoplasms in the nervous system.
abstract: Pseudotumors are frequent in the nervous system and form a category of lesions that are fraught with peril for the pathologist unaware of the similarities and differences with neoplasms. The most common pseudoneoplasms in the nervous system are demyelinative, inflammatory and vascular. Even normal histology can be mistaken for neoplasm.
