History: 55 year old male with new onset seizures.
This case is a nice example of a ring enhancing mass in the brain. The typical mnemonic used for a solitary ring enhancing mass in the brain is MAGIC-DR which stands for Metastases, Abscess, Glioblastoma Multiforme, Infarct, Contusion, Demyelinating disease (tumefactive multiple sclerosis), and Radiation Necrosis and Resolving hematoma.
The final diagnosis after surgery in this patient was Glioblastoma Multiforme, a rapidly enlarging malignant astrocytic tumor characterized by necrosis and neovascularity. Typically these occur in patients 45-75 years old, and comprise about 10-15% of all intracranial neoplasms. They present with seizures and focal neurological symptoms, and the prognosis is poor, with death commonly occurring within 9-12 months.
