Summary
Primary central nervous system (CNS) lymphoma is rare, especially in the cerebellopontine angle. This case highlights a unique presentation of this uncommon malignant lymphoma in an immunocompromised patient.
Area of Science:
- Neurology
- Oncology
- Pathology
Background:
- Primary malignant lymphoma of the central nervous system (CNS) is a rare condition.
- Immunocompromised individuals face an elevated risk of developing malignant lymphoma.
- Malignant lymphomas can manifest in various locations within the CNS.
Observation:
- A rare case of primary CNS lymphoma presented as a solitary lesion in the cerebellopontine angle.
- The patient had a history of rectal cancer extirpation four years prior to this presentation.
- This specific presentation of malignant lymphoma is exceptionally uncommon.
Findings:
- The cerebellopontine angle is an extremely rare site for primary CNS lymphoma.
- Only ten cases of malignant lymphoma presenting as a cerebellopontine angle mass have been previously reported.
- Of the reported cases, seven were primary CNS lymphomas and three were secondary.
Implications:
- This case underscores the importance of considering rare diagnoses in the differential for cerebellopontine angle masses.
- Further research into the specific risk factors and presentation patterns of primary CNS lymphoma is warranted.
- Early and accurate diagnosis is crucial for effective management of primary CNS lymphoma.
