A rare brain tumor, subdural plasma cell granuloma, caused seizures and paralysis in a 62-year-old man. This case highlights the lesion's chronic progression and introduces focal calcification as a new imaging finding.

Area of Science:

  • Neurology
  • Neurosurgery
  • Pathology

Background:

  • Subdural plasma cell granulomas are rare, benign tumors that can cause significant neurological deficits.
  • Intracranial plasma cell granulomas are typically slow-growing but can present with progressive symptoms.

Observation:

  • A 62-year-old man presented with focal seizures, tinnitus, and progressive left hemiparesis.
  • Imaging revealed an extensive subdural plasma cell granuloma.
  • A five-year clinical and radiologic follow-up documented the lesion's chronic and progressive nature.

Findings:

  • This case is the first to report focal calcification within an intracranial plasma cell granuloma.
  • The study reviews the imaging, neuropathologic, and clinical characteristics of this rare lesion.

Implications:

  • The presence of focal calcification may aid in the diagnosis of intracranial plasma cell granulomas.
  • Understanding the chronic and progressive nature of these lesions is crucial for patient management.
  • This case expands the spectrum of imaging findings associated with plasma cell granulomas.
