Summary

Primary leptomeningeal lymphoma, a rare condition, can complicate with subdural hematoma. Early diagnosis via cerebrospinal fluid analysis and specific MRI sequences is crucial for patients with neurological symptoms.

Area of Science:

  • Neurology
  • Oncology
  • Radiology

Background:

  • Primary leptomeningeal lymphoma (PML) is an exceptionally rare neoplastic infiltration of the central nervous system's meninges.
  • The neuroradiological features and complications of PML remain incompletely understood, necessitating further case reporting.

Observation:

  • A patient presented with headache, vomiting, and progressive cranial nerve palsy.
  • Cerebrospinal fluid analysis revealed monoclonal proliferation of atypical B-lymphocytes, indicative of lymphoma.
  • Neuroradiological imaging demonstrated a left frontal mass and subacute subdural hematoma, with characteristic high signal intensity in the subarachnoid space on proton-weighted MRI suggesting PML.

Findings:

  • Surgical resection and histopathological examination confirmed primary leptomeningeal lymphoma with a complicating subdural hematoma.

  • Systemic evaluation excluded extraneural lymphoma, solidifying the diagnosis of primary leptomeningeal lymphoma.
  • The case suggests a potential association between subdural hematoma and primary leptomeningeal lymphoma.

    • Implications:

    • Subdural hematoma should be considered in the differential diagnosis of patients with unexplained neurological deficits and suspected leptomeningeal disease.
    • Proton-weighted MRI and cerebrospinal fluid analysis are vital diagnostic tools for identifying PML, especially when concurrent subdural hematoma is present.
    • This case underscores the importance of comprehensive neuroimaging and fluid analysis in diagnosing rare neurological conditions.
