RESUMO
Objective:To discuss the diagnosis, treatment and outcome of patients with gliomatosis cerebri (GC). Methods:Retrospectively reviewed the clinical manifestations and radiological appearances of 6 patients with GC, which were diagnosed in our hospital between 1993 and 2003. We employed surgical treatment in three patients, stereotactic biopsy in two, and the other one received both biopsy and surgery. Results: The lesions of GC infiltrated more than two lobes in brain. CT studies showed diffuse hypodensity changes and enhancement was absent in four patients. MRI examinations revealed isointense or hypointense regions on T1WI, and uniformly high signal on T2WI. MRI also disclosed structural enlargement. All patients received radiotherapy after surgery and three patients underwent chemotherapy additionally. Five patients died during follow up with average course of 16.4 months. Conclusion:MRI examination is valuable in the diagnosis and the prognosis of GC is poor.
