MRI of cervical spine (axial T2) revealing osteochondroma of the right first rib (at yellow arrowhead)MRI - Magnetic Resonance ImagingRight paraspinal mass that appears to arise from the right first rib with continuity of the medullary cavity and bright peripheral T2 signal suggesting a cartilage cap. Findings are most consistent with osteochondroma. However, given the widening of the adjacent neural foramina and apparent extension to the neural foramina, ganglioneuroblastoma could be considered, though this would be less likely given the profuse calcification.
