Abstract

Introduction. Chronic recurrent multifocal osteomyelitis (CRMO) is a pediatric autoinflammatory disorder that is characterized by multiple sterile inflammatory bone lesions with a relapsing and remitting course. CRMO belongs to the autoinflammatory family of rheumatologic disorders based on absence of significant titers of autoantibodies and autoreactive T-lymphocytes. In absence of pathognomonic clinical, radiographic or pathological features, diagnosis can be challenging.

Case presentation. We report an unusual case of a 3-year-old girl presenting back pain, neurogenic bladder and syringomyelia. A tethered cord was diagnosed and treated, improving urinary function. Despite the surgical treatment, back pain was persistent. A whole body MRI showed multiple lesions compatible with chronic recurrent multifocal osteomyelitis.

Conclusion. CRMO shares imaging features with other diseases. It is important for neurosurgeons and radiologists to be able to differentiate other diseases from CRMO because prognosis varies from completely benign to frankly malignant.
