a A 9-year-old girl from Ethiopia, with cervical lymph nodes and weight loss, under suspicion of having tuberculosis. Fluid collection was seen on ultrasound at level II and the patient underwent CT to exclude a retropharyngeal abscess. CT showed multiple cervical and mediastinal lymph nodes, but also destruction of the end plate of the corpus of C2 with a fragment dislocated anteriorly (arrow). b CT in the soft tissue kernel clearly shows a prevertebral fluid collection with rim enhancement, but also posterior extension in the spinal canal, with enhancement. The diagnosis is a tuberculous spondylodiscitis. c On the sagittal T1 contrast-enhanced fat-saturated image, one can clearly see the anterior abscess, but also the intraspinal extension of the abscess in the spinal canal
