Abstract
BACKGROUND: Cervical ribs and elongated transverse process are congenital anatomical variations
incidentally seen during conventional radiography and are usually ignored as most cases are of less clinical
relevance. Cervical rib is generally noted in 1-2 % of the population. The main objective of this study was to
find out the prevalence of this variation in our adult population.
METHODS: It is a retrospective cross sectional study which was conducted in Karachi at Ziauddin university
hospital Kemari campus radiology department targeting adult population above nineteen years. Study
period was six months between January to July 2015. Subject’s x-ray chest P/A view were taken which were
analyzed by radiologist for presence of these anatomic variations.
RESULT: In this study one thousand conventional frontal chest radiograph were taken in which 460 were
males and 540 females patients who were analyzed for cervical ribs and elongated transverse process.
Cervical rib was seen in thirty six patients with 2:1 female to male ratio. Elongated transverse process was
noted in two hundred and twenty five subjects. Eleven patients having cervical ribs were symptomatic.
CONCLUSION: The prevalence of cervical rib and elongated transverse process as delineated by our study
is slightly higher than reported in other populations. We also conclude that conventional radiography is
effective diagnostic tool to determine presence of this anatomical variation.
