Introduction[edit | edit source]
Cervical rib is an extra rib[1] that forms above first rib[2] which grows from the base of the neck just above the collarbone. It can be on right, left or both sides and may be fully formed bony rib or a thin strand of tissue fibre. They vary in size and shape.
In few cases, people having cervical rib may develop thoracic outlet syndrome[3] because of pressure on the nerves that may be caused by the presence of the rib. Partially formed extra rib may end in a swelling that shows as a lump in neck or it may tail off into a fibrous band of tissue that connects to the first proper rib[4]. Most cases are not clinically relevant and do not have symptoms. They are generally discovered incidentally during x-rays and CT scans.[5]
A cervical rib represents a persistent ossification of the C7 lateral costal element. During early development, this ossified costal element typically becomes re-absorbed. Failure of this process results in a variably elongated transverse process or complete rib that can be anteriorly fused with the T1 first rib below.[6]
