RESUMO
Gliomatosis cerebri is an uncommon glial neoplasm that is exceedingly rare in children and difficult to diagnose. The authors describe the presentation and diagnosis of GC in 3 children ages 12, 14, and 16 years. These children exhibited signs and symptoms of increased intracranial pressure as well as other vague or site specific neurological signs. Because clinical presentation, CSF analysis, and neuroimaging were nonspecific, a stereotactic biopsy to obtain tissue for pathological review was ultimately necessary to confirm the diagnosis. These pediatric cases underscore the limitations of relying solely on clinical presentation and neuroimaging and call to attention the essential role of neurosurgical intervention. The authors emphasize the need to maintain gliomatosis cerebri in the differential diagnosis of children presenting with diffuse neurological signs and MR imaging evidence of widespread, infiltrative lesions.

Gliomatosis cerebri (GC) is a diffuse infiltrating glial neoplasm of astrocytic origin. GC in children is rare and difficult to diagnose, often presenting with a variety of signs and symptoms that may mimic encephalitis. We discuss here the presentation and diagnosis of GC in 2 children who were initially suspected to have acute disseminating encephalomyelitis. In this report we underscore the limitations of relying on clinical presentation and neuroimaging as well as the essential role of pathologic evaluation for the diagnosis of GC in children.
