Summary
Hairy cell leukemia can rarely lead to isolated cerebral vasculitis, a condition affecting brain arteries. This case highlights the importance of considering vasculitis in HCL patients with neurological symptoms.
Area of Science:
- Neurology
- Hematology
- Pathology
Background:
- Hairy cell leukemia (HCL) is a rare chronic lymphoid leukemia.
- An association exists between HCL and generalized necrotizing vasculitis, often polyarteritis type.
- Neurological complications in HCL are uncommon.
Observation:
- A 74-year-old man with diagnosed HCL developed confusion and focal neurological signs after 5 years.
- Despite investigations and treatment, the patient's condition deteriorated, leading to death.
- Postmortem examination revealed isolated primary necrotizing vasculitis of the cerebral arteries.
Findings:
- No leukemic infiltration of the central nervous system was identified.
- The autopsy confirmed isolated cerebral necrotizing vasculitis as the cause of neurological symptoms.
- This represents the first reported case of isolated cerebral vasculitis associated with HCL.
Implications:
- This case underscores the importance of considering cerebral vasculitis in HCL patients presenting with neurological deficits.
- Differential diagnosis should include infective (mycotic) arteritis, especially in immunocompromised patients.
- Further research may elucidate the mechanisms linking HCL and isolated central nervous system vasculitis.
