Introduction:
Few cases of patients with both Familial Mediterranean Fever (FMF) and Multiple Sclerosis (MS) have been reported, mainly from Turkey. Central nervous system manifestations are rare in FMF.
Case Report:
We report the case of a 37-year-old right-handed man with FMF diagnosed at 17 the age of years and successfully treated with colchicine. The patient was born in Algeria and lived in France since he was four years old. He had a brother who had multiple sclerosis. When the patient was 23 years old, he experienced diplopia and leg numbness that resolved spontaneously without treatment. Ten years later, new neurological events appeared every six months and were treated with corticoid-steroids. The diagnosis of MS was made. In 2006, he was hospitalized for new explorations in order to search for neuro-Behçet's disease, because of the development of a canker sore. There was no argument for neuro-Behçet's disease.
Discussion:
Neurological complications of FMF are rare. It is important to rule out a neuro-Behçet disease in a FMF patient with neurological disorders. Previous studies and case reports on the association between FMF and MS have failed to draw a clear conclusion as to whether this is a true association or a simple coincidence. In our patient's clinical situation, we found no argument for changing the treatment of MS and FMF.
Insights
This case report details a patient with Familial Mediterranean Fever (FMF) and Multiple Sclerosis (MS), highlighting rare neurological complications and the importance of differentiating from neuro-Behçet disease.
Area of Science:
- Neurology
- Rheumatology
- Immunology
Background:
- Familial Mediterranean Fever (FMF) is a genetic autoinflammatory disorder.
- Central nervous system (CNS) involvement is uncommon in FMF patients.
- The co-occurrence of FMF and Multiple Sclerosis (MS) is rarely documented.
Observation:
- A 37-year-old male with a history of FMF since age 17, treated with colchicine, presented with neurological symptoms.
- The patient experienced diplopia and leg numbness, followed by recurrent neurological events consistent with MS.
- Investigations for neuro-Behçet disease were negative despite aphthous ulcer development.
Findings:
- The case highlights a patient with both FMF and MS, presenting with neurological manifestations.
- The diagnostic process involved ruling out neuro-Behçet disease, a crucial differential diagnosis in FMF patients with neurological disorders.
- Current treatment for both FMF and MS remained unchanged based on the clinical presentation.
Implications:
- This case contributes to the limited literature on the association between FMF and MS.
- It underscores the importance of a thorough differential diagnosis for neurological symptoms in FMF patients.
- Further research is needed to clarify whether the co-occurrence of FMF and MS is coincidental or represents a true association.
