A patient presented with 2 months history of increased ICP, with massive parietal edema, CT/MRI shows single and were circumscribed region lesion

(A) Granuloma > Granuloma usually presents with increased ICP, with massive parietal edema. CT/MRI shows single circumscribed region lesion. Gliomas include astrocytomas, oligodendrogliomas and mixed tumours. Common sites include the cerebellum, optic nerve and chiasma, hypothalamus and brainstem. Diffuse astrocytomas (WHO grade II) are most common in the fourth decade of life and often present with seizures or are incidental findings. CT scan shows enhancement which is often irregular around a centre of low density which may represent necrosis calcification may be present. Cerebral metastases are by far the most common intracranial tumours and will affect approximately one in every four cancer sufferers. They tend to occur in the fifth to seventh decades. The majority of patients with cerebral metastases have multiple lesions. Metastatic tumours show isodense on unenhanced CT and enhance vividly on intravenous contrast.
