How is a hypoplastic first rib differentiated from a cervical rib?
Hypoplastic first rib: Hypoplastic first rib is not uncommon to be encountered in chest radiograph. The reported prevalence is 0.2% of chest radiographs. It can be differentiated from cervical rib by the direction of transverse process of the attached vertebra, as the T1 transverse process is directed superiorly.
Is there a hypoplastic right 12th rib and agenesis?
Hypoplastic right 12th rib and agenesis of the left 12th rib, simulating a right transverse processes fracture of the first lumbar vertebra. There is also a lumbosacral transitional vertebra with a neo-articulation between a large right tranverse process and the sacrum.
