Brucella Case That Led to Atlantoaxial Spinal Instability in Childhood.

BACKGROUND

Atlantoaxial subluxation caused by Brucella infection is rarely seen in children.

CASE DESCRIPTION

C1-C2 dislocation, erosion in the odontoid bone, and compression to the brainstem were detected on cervical computed tomography and magnetic resonance imaging in a 6-year-old patient who suffered neck pain, deviation to the right in the neck, fever, and pain in his extremities. He was hospitalized in the Clinic of Pediatric Infectious Diseases. Positive Brucella agglutination tests were obtained, so C1-C2 stabilization and fusion were performed. Antibrucellosis antibiotic treatment was administered for 6 months. It was suggested that the dislocation was related to odontoid erosion and laxity of the atlantoaxial ligamentous structures during Brucella infection.

CONCLUSIONS

Atlantoaxial dislocation and instability develops secondarily to paravertebral abscesses, only rarely. Like brucellosis of childhood, granulomatous infectious diseases rarely cause atlantoaxial subluxation or dislocation. Torticollis and neck pains should be taken seriously for the purpose of early diagnosis of patients at risk in endemic regions. Stabilization and fusion should be performed when instability is detected, and these patients should be assessed with both pediatric infectious diseases and neurosurgery clinics. Our case is the first one in the literature in which atlantoaxial instability developed due to Brucella infection and stabilization was performed.
