RESUMEN
We report two cases of cerebral deep venous thrombosis in female adults. The first patient presented with headaches and confusion 20 days postpartum. Deep cerebral internal venous thrombosis was suspected based on the CT scan showing bilateral hypodensity in the thalamus and internal capsules. The diagnosis was confirmed on cerebral angiography. The patient was treated but died within 3 weeks of the onset of symptoms. The second patient had no obvious predisposing factors. She presented with confusion and fever. The diagnosis was strongly suggested by the CT scan, which showed spontaneous high density in the deep venous system associated with bilateral hypodensities in the thalamus and internal capsules. Venous MR angiography revealed obliteration of internal cerebral veins and the great vein of Galen. Ten days after appropriate therapy, the patient recovered completely.

The Gliomatosis Cerebri (GC) is an infiltrating and rare primitive tumour of the brain. It is characterized by diffuse neoplastic proliferation of glial cells involving of at least two lobes of the brain, without a distinct tumor mass and with the preservation of the anatomical and neuronal architecture. According to the WHO classification, GC is categorized as a high-grade neuroepithelial tumor of uncertain origin (GradelV). Now the diagnosis is facilitated via stereotactic biopsies of the representative lesion identified in magnetic resonance. Our objective is to present 4 new cases, and recall the clinical and radiological features and the prognosis.

We report a case of sphenoidal plasmocytoma in a 57-year-old male revealing multiple myeloma. MRI showed a tumor located in the sphenoid sinus with local extension. Diagnosis was made by histology after transsphenoidal resection. We discuss the imaging features of plasmocytomas and review the principal differential diagnoses.
