Overview

On the basis of seizure, visual disturbance, and constitutional symptoms, astrocytoma must be differentiated from oligodendroglioma, meningioma, hemangioblastoma, pituitary adenoma, schwannoma, primary CNS lymphoma, medulloblastoma, ependymoma, craniopharyngioma, pinealoma, AV malformation, brain aneurysm, bacterial brain abscess, tuberculosis, toxoplasmosis, hydatid cyst, CNS cryptococcosis, CNS aspergillosis, and brain metastasis.

Differentiating astrocytoma from other diseases on the basis of seizure, visual disturbance, and constitutional symptoms

On the basis of seizure, visual disturbance, and constitutional symptoms, astrocytoma must be differentiated from oligodendroglioma, meningioma, hemangioblastoma, pituitary adenoma, schwannoma, primary CNS lymphoma, medulloblastoma, ependymoma, craniopharyngioma, pinealoma, AV malformation, brain aneurysm, bacterial brain abscess, tuberculosis, toxoplasmosis, hydatid cyst, CNS cryptococcosis, CNS aspergillosis, and brain metastasis.
