Familial Mediterranean Fever with Pseudo-Septic Arthritis: A Case Report and Review of the Literature.

FMF can mimic septic arthritis resulting in unnecessary expensive and invasive interventions and prolonged courses of antibiotics. Pseudo-septic arthritis is usually associated with M694V homozygous mutation and can complicate FMF at any time throughout the disease course. It is important to consider FMF in the differential diagnosis of septic arthritis particularly with a family history of FMF and in patients from communities with high prevalence of MEFV gene mutation.
