Gliomatosis cerebri, a rare diffusely infiltrating astrocytoma, was discovered on the postmortem examination of a 22-year-old woman with a 13 year history of seizures. Computed tomography of the brain revealed bifrontal white matter low density changes that were most consistent with a demyelinating or dysmyelinating disorder.

Gliomatosis Cerebri is an unusual neoplastic entity that affects the central nervous system (C.N.S.); it consists of a marked proliferation of glial cells with variable degrees of differentiation in extensive areas of the brain and/or spinal cord. The process is primarily an infiltrative one rather than destructive. Most of the cases are diagnosed at autopsy. The authors report a new case of Gliomatosis Cerebri in a 46 year old woman, with a long clinical history--15 years--of focal seizures; and during the year prior to her admission: behavioral changes, vertigo, urinary incontinence and frequent falls. C.N.S. imaging revealed extensive involvement of the white matter of both cerebral hemispheres. Stereotactic guided biopsy showed a moderately cellular astrocytic neoplasm. A review of the medical literature led to the conclusion that the present case constitutes one of the very few examples in which the diagnosis of Gliomatosis Cerebri was achieved ante-mortem.

Gliomatosis cerebri is an infrequent tumor of neuroepithelial origin presenting with deterioration of cognitive functions, behavioral and mental changes, motor weakness, headache, and seizures. Laboratory data are unconclusive. MRI appears to be the imaging modality of choice and mainly reveals a bilateral and diffuse infiltration of midline adjacent brain structures whose anatomical configuration remain intact. MRI- or CT-guided stereotactic biopsy is advised as the diagnostic procedure in suspected cases. A 9-year-old girl with diffuse cerebrospinal gliomatosis, investigated with sequential cranial CT scans, and MRI-verified spinal cord involvement is reported, and the corresponding literature is reviewed.

Gliomatosis cerebri is a rare glial neoplasm, characterized by diffuse brain infiltration with relative preservation of the underlying cytoarchitecture. Its clinical and radiologic features are not specific and its antemortem diagnosis is difficult. We report a case of gliomatosis cerebri in a 68-year-old woman presenting with gait disturbances and episodic seizures. MRI showed bilateral white matter hypersignal intensities on Flair sequences and brain biopsy revealed a poorly cellular proliferation of neoplasic glial cells strongly expressing OLIG-2, Ki-67 and occasionally GFAP, without alpha-internexin expression. The patient status worsened rapidly and she died 2 months after the initial symptoms. Postmortem brain examination confirmed gliomatosis cerebri and revealed a focal glioblastoma in the frontal cortex, with nuclear p53 expression in the highest malignant areas. Gliomatosis cerebri should be included in the differential diagnostic of diffuse brain lesions. Antemortem diagnosis, although difficult, can be assessed by IRM and careful biopsy examination. Progression to glioblastoma has been seldom reported, enhancing the controversy about the etiopathogenesis of this rare tumour.
