Introduction: Chronic recurrent multifocal osteomyelitis (CRMO) is a rare autoimmune disorder of childhood and adolescence which often manifests as recurring episodes of inflammatory bone pains. Spinal involvement is rare; however, recent studies advocate full body magnetic resonance imaging in all suspected cases to pick up asymptomatic lesions early to prevent complications. Spinal involvement may manifest as fractures, scoliosis, or kyphotic deformity.
Case Report: We present a case of a 12-year-old boy who had three-level involvement of thoracic spine, T6-T8, and was worked up and managed for pathological fracture of spine. He underwent biopsy for the same and was later diagnosed as CRMO. Here, we discuss the diagnostic challenges involved in CRMO, need for biopsy, and the management options available.
Conclusions: Identifying CRMO is challenging and remains a diagnosis of exclusion. Nonsteroidal anti-inflammatory drugs often constitute the first line of treatment and other drugs such as bisphosphonates and biologics such as TNF-alpha antagonists are reserved for more severe cases. Although CRMO is considered a benign disease, recent data suggest up to 50% rate of residual impairments despite optimal management.
