BACKGROUND AND PURPOSE Cervical ribs are congenital variants that are known to cause TOS or brachial plexopathy in up to 10% of the affected individuals. We investigated how often cervical ribs are present on cervical spine CT scans to determine the incidence in humans and the percentage of reported cervical ribs. MATERIALS AND METHODS Cervical spine CT scans and the reports of 3404 consecuti...

introduction: cervical rib is relatively uncommon congenital abnormality that originates from the seventh cervical vertebrae and rarely from the sixth vertebrae. the purpose of this paper is to consider that this abnormal condition is an important cause of neurovascular compression at the thoracic outlet. methods: in this study all patients who were referred to radiology department of isfahan h...

A familiarity with the anatomy of some types of bone anomalies is necessary for clinicians involved in many medical areas. The aim of this paper is to review the newest literature concerning the morphology, embryology, clinical image, and therapeutic methods of the cervical ribs in the humans. The incidence of cervical ribs has been found to vary from 0.58% in Malaysian population to 6.2% in Tu...

A 4-year-old intact female, mixed breed dog was presented with a complaint of dyspnea. Clinical examination revealed symptoms related to disease of the upper airways. Radiographic findings were consistent with tracheal collapse associated with anomalies involving the seventh cervical vertebra and the first ribs bilaterally. Radiographs were highly suggestive of cervical ribs; computed tomograph...

Cervical ribs are an anomaly that arise from the lowest cervical vertebrae but their relationship to thoracic outlet syndrome (TOS) is not so constant that the two conditions should be seen as synonymous. Perhaps no more than 10% of people who have cervical ribs develop TOS and the syndrome may well occur in the absence of ribs. Diagnosis of TOS may be difficult and depends upon a thorough hist...

A cervical rib generally arises from the seventh cervical vertebra and is known as an anomalous accessory rib or “Eve’s rib” [1]. A recent literature survey reported that cervical ribs are present in less than 1% of the normal population and are asymptomatic in about 90% of cases [2]. Complete cervical ribs are fused with the tubercle on the upper aspect of the first thoracic rib, very close to...

Purpose: Rib anomalies include numerical and structural categories. This study investigates the costal abnormalities by computed tomography scan in an Iranian population. Methods: In a retrospective study, 400 Chest CT scans (225 (56.2%) male, and 175 (43.8%) female) aging from 18 to 89 were investigated for one year (2020 to 2021). Images were carefully observed and various abnormalities suc...
