[Gliomatosis cerebri: two case reports with atypical clinical and neuroradiologic findings].

The diagnosis of the rare disease Gliomatosis cerebri requires the correlation of clinical, radiological,and pathological findings. We report on two patients with intravitally diagnosed gliomatosis cerebri. Due to the unusually high malignancy of the tumor cells, diagnosis was complicated by atypical findings such as gadolinium enhancement in MRI and raised intracranial pressure. The clinical course, differential diagnosis,and literature are summarized briefly.
