GLIOMATOSIS CEREBRI PDF

Resources Gliomatosis cerebri Gliomatosis cerebri GC is a very rare primary brain tumour, characterized by the diffuse and extensive infiltration of neoplastic glial cells across more than two contiguous lobes of the brain. Characteristically, it may cross the midline and affect both hemispheres. More frequently, it affects the brain, but it can also affect the brainstem and spinal cord. It can affect patients of all ages, being more frequent in adults, as is reported in published medical literature2,3.

Resources Gliomatosis cerebri Gliomatosis cerebri GC is a very rare primary brain tumour, characterized by the diffuse and extensive infiltration of neoplastic glial cells across more than two contiguous lobes of the brain.

Characteristically, it may cross the midline and affect both hemispheres. More frequently, it affects the brain, but it can also affect the brainstem and spinal cord. It can affect patients of all ages, being more frequent in adults, as is reported in published medical literature2,3. In terms of incidence, there is no clear association with sex, although some publications show a slightly higher incidence in males. They described 88 patients ranging from 4 months to 21 years at the time of diagnosis, with an average age of They also described a preponderance of boys, with a male to female sex ratio of 1.

GC is therefore a clinical —a group of signs and symptoms- and a radiological —based on MRI findings- diagnosis, not a histologic one. Tumour examination must be done —as we will discuss later- and confirms the glial nature of the tumour, but does not define it. This is the more frequent type.

GC clinical presentation The symptoms of the disease at diagnosis are variable, depending upon which areas of the brain are affected by the tumour, the age of the patient and the growth rate. There are no specific symptoms for GC, however, most of patients present with some clinical characteristic findings4,7: Seizures Changes in personality or behaviour Changes in memory or cognitive abilities Problems with vision Loss of balance or problems walking Fatigue, changes in activity levels Weakness, numbness, tingling, or changes in feeling on one side of the body When diagnosis is suspected, a brain and spine MRI should be performed looking for the radiologic diagnostic criteria.

Gliomatosis Cerebri

MRI of gliomatosis cerebri in the brain. This means it begins in the brain or spinal cord. This tumor is no longer recognized as a formal diagnosis, rather gliomatosis cerebri refers to a special pattern of diffuse and extensive growth of glioma cells, invading multiple lobes of the brain. More research is needed to discover the origin of these tumors and to improve their treatment.

Gliomatosis cerebri

It is most commonly encountered in anaplastic astrocytomas 8. Classification Gliomatosis cerebri can be divided into two types 7: type 1: no discrete mass usually IDH wild-type 8 type 2: discrete mass with further diffuse CNS involvement IDH1 mutation more common in this subtype 7 Radiographic features CT CT can be normal as lesions are often isodense to normal brain parenchyma. There is a relative lack of mass effect and distortion compared to the extensiveness of involvement. There may be an ill-defined asymmetry or subtle hypoattenuation of the involved brain parenchyma. MRI Mass effect and enhancement are often minimal despite large portions of the brain being involved. There is a loss of grey-white matter differentiation and diffuse gyral thickening.
