The initial manifestation of hip pain, coupled with progressive symptoms over several years and findings in multiple magnetic resonance imaging (MRI) scans, culminated in the diagnosis of chronic recurrent multifocal osteomyelitis (CRMO). Subsequently, the patient was diagnosed with type 1 diabetes (T1D), celiac disease, and juvenile idiopathic arthritis.The therapeutic course proved challenging, marked by unsuccessful attempts with nonsteroidal anti-inflammatory drugs (NSAIDs), and biphosphonates. However, a stable clinical status was ultimately achieved upon the introduction of methotrexate, concomitant with insulin therapy for diabetes and the implementation of a gluten-free diet for celiac disease.ConclusionsOur case showed that the combination of autoimmune and autoinflammatory diseases, brought not only a challenging diagnostic process, but also complicated treatment.
