Background Familial Mediterranean fever (FMF) is an inherited inflammatory disorder characterized by attacks of fever with polyserositis. Objective The purpose of this study was to evaluate pediatric patients with FMF who had central nervous system (CNS) findings. Materials and Methods Our medical records database for 2003 to 2014 was screened retrospectively. In total, 104 patients with FMF were identified, 22 of whom had undergone neurological examination for CNS symptoms. Results Neurological findings included headache in 16 patients (72.7%), epilepsy in 6 patients (27.3%), pseudotumor cerebri in 2 patients (9.1%), tremor in 2 patients (9.1%), and multiple sclerosis in 1 patient (4.5%). The most common MEFV gene mutation was homozygous M694V (40.9%). Conclusions Patients with FMF can present with various CNS manifestations. Further studies that include large populations are needed to elucidate the neurological manifestations of FMF.
