Abstract: Chronic recurrent multifocal osteomyelitis (CRMO) is an aseptic, autoinflammatory condition affecting bone. It is an uncommon entity of uncertain etiology that result in multifocal lesions with pain, swelling, frequent exacerbations and remissions. Clavicle is the most common affected site. Mandibular involvement is considered rare. CRMO can mimic the features of infective osteomyelitis, thus unnecessarily subjecting the patient to a prolonged course of antibiotics, radiation exposure and multiple biopsies. Radiographically, magnetic resonance imaging and bone scintigraphy are the cornerstone for confirming the CRMO lesions. Considering the rarity of this condition, we present the clinical and radiographic features of CRMO in an adolescent male along with a one year follow up. Summary: A 13-year-old male presented with a chief complaint of pain and facial swelling on the left side. His medical history was significant for CRMO and hospitalization for recurrent right facial swelling, tenderness and chronic ankle pain. Extra-oral radiographs depicted a normal bone pattern but mild soft tissue swelling over the left side of the mandible. MRI revealed bone marrow edema in the left mandible, consistent with the known CRMO.References: Monsour PA DJ.
