Eight-year-old female with cervical spine osteochondroma. Cervical spine osteochondroma in an asymptomatic 8 year-old female. Axial (A) and Sagittal (B) CT images in bone windows (C 570, W 3077) demonstrate a circumscribed broad based bony lesion arising from the C4 posterior vertebral body and protruding into the central canal. There is cortical continuity between the lesion and the parent vertebra.

Although no acute fractures were identified, a solitary, well-circumscribed bone tumor was incidentally identified arising from the posterior margin of the C4 vertebral body, with cortical continuity with the parent vertebra (Fig. 1).
Eight-year-old female with cervical spine osteochondroma. MR images. Axial T2 (4100/100)-weighted (A), sagittal T2 (3500/135)-weighted (B), and sagittal T1 (400/12)-weighted postcontrast (C) images show a circumscribed lesion isointense to bone marrow on all sequences, arising from the C4 posterior vertebral body, with marrow continuity with the parent vertebra. A small, mildly hyperintense cartilage cap is possibly identified on the T2-weighted images. The lesion protrudes into the central canal, resulting in compression and flattening of the anterior spinal cord.

The MRI demonstrated marrow continuity of the lesion with the C4 vertebral body and a possible small cartilage cap (Fig. 2), consistent with an osteochondroma.
