Differential Diagnosis

Intracranial metastases must be differentiated from:[1][2]

  • CT scan of a 60 year old patient who developed left-handed weakness which improved with corticosteroids and neurological examination revealing left pronator drift and left sided arm and leg weakness demonstrates right frontoparietal hyperdense intra-axial lesion that enhances in post contrast study. Small surrounding vasogenic edema and no significant mass effect is observed.[3]
