Case record...Epidural secondary CNS lymphoma

A 32-year-old male presented with a single grand mal seizure. CT scans showed extradural masses in the left parietal and frontal regions, compressing the brain and ventricles. Surgery revealed nodular dural thickening without brain infiltration. Biopsy diagnosed non-Hodgkin B-cell lymphoma. Further staging found extensive extraneural disease, though the CNS manifestations were the initial presentation. The patient was referred for oncology management for epidural secondary CNS lymphoma.
