Summary
Infectious mononucleosis can cause diverse neurological issues, including myelitis, cerebellar symptoms, and optic neuritis. Early diagnosis is key, especially in young patients with unexplained neurological signs.
Area of Science:
- Neurology
- Infectious Diseases
- Immunology
Background:
- Infectious mononucleosis, commonly caused by Epstein-Barr virus, is typically a self-limiting illness.
- Neurological complications, though infrequent, can significantly impact patient health.
- This study focuses on three distinct cases of neurological manifestations secondary to infectious mononucleosis.
Observation:
- Case 1 presented with myelitis, a known neurological complication.
- Case 2 exhibited cerebellar symptoms, including ataxia and gait disturbance, with MRI revealing previously unreported vermis atrophy.
- Case 3 was diagnosed with bilateral optic neuritis.
Findings:
- Neurological sequelae of infectious mononucleosis are varied and can mimic other conditions.
- Magnetic resonance imaging identified unique findings such as vermis atrophy in a patient with cerebellar symptoms.
- Diagnosis may require serial serological testing due to potential initial ambiguity.
Implications:
- Infectious mononucleosis should be considered in the differential diagnosis of neurological symptoms in young individuals.
- Recognition of these neurological manifestations is crucial for timely and appropriate patient management.
- Further research into the pathogenesis and specific MRI findings of infectious mononucleosis-related neurological complications is warranted.
