TL;DR: In the emergency department setting, it is vital for the interpreting radiologist to not only identify the presence of rib injuries but also alert the clinician about organ-specific injury, specific traumatic patterns, and acute rib trauma complications that require emergent attention.
Abstract: The ribs are frequently affected by blunt or penetrating injury to the thorax. In the emergency department setting, it is vital for the interpreting radiologist to not only identify the presence of rib injuries but also alert the clinician about organ-specific injury, specific traumatic patterns, and acute rib trauma complications that require emergent attention. Rib injuries can be separated into specific morphologic fracture patterns that include stress, buckle, nondisplaced, displaced, segmental, and pathologic fractures. Specific attention is also required for flail chest and for fractures due to pediatric nonaccidental trauma. Rib fractures are associated with significant morbidity and mortality, both of which increase as the number of fractured ribs increases. Key complications associated with rib fracture include pain, hemothorax, pneumothorax, extrapleural hematoma, pulmonary contusion, pulmonary laceration, acute vascular injury, and abdominal solid-organ injury. Congenital anomalies, including supernumerary or accessory ribs, vestigial anterior ribs, bifid ribs, and synostoses, are common and should not be confused with traumatic pathologic conditions. Nontraumatic mimics of traumatic rib injury, with or without fracture, include metastatic disease, primary osseous neoplasms (osteosarcoma, chondrosarcoma, Ewing sarcoma, Langerhans cell histiocytosis, and osteochondroma), fibrous dysplasia, and Paget disease. Principles of management include supportive and procedural methods of alleviating pain, treating complications, and stabilizing posttraumatic deformity. By recognizing and accurately reporting the imaging findings, the radiologist will add value to the care of patients with thoracic trauma.

TL;DR: All palpable, asymptomatic, anterior chest wall lesions were benign and usually related to normal variations in the bone or cartilage of the chest wall, which should be considered when decisions are made with regard to imaging.
Abstract: PURPOSE: To review results from cross-sectional imaging studies performed to evaluate asymptomatic anterior chest wall lesions in children. MATERIALS AND METHODS: All magnetic resonance (MR) images or computed tomographic (CT) scans of the chest obtained from 1989 to 1996 for evaluation of asymptomatic, palpable, focal, anterior chest wall lesions in otherwise healthy children were reviewed. Fifty-one children were considered for the study. Findings from 27 examinations in 27 children (13 underwent MR imaging, and 14 underwent CT) were included in the study. All children had normal radiographs of the region. Twenty-four patients did not meet the inclusion criteria and were excluded. RESULTS: The cause of the lesion palpated at physical examination was identified in 26 of 27 patients: prominent anterior convex ribs in 10 patients; "tilted" sternum in six; prominent asymmetric costal cartilage in four; bifid rib in one; and well-defined, small (< 1-cm) subcutaneous nodule adjacent to costal cartilage in fiv...

TL;DR: A chromosomal abnormality in a patient with cysts of the jaw, recurrent nevoid basal cell carcinomata and bifid ribs, except for the unusual length of one arm of one of the chromosomes No. 1, is described.
Abstract: A chromosomal abnormality in a patient with cysts of the jaw, recurrent nevoid basal cell carcinomata and bifid ribs is described. The patient presented a normal female complement, except for the unusual length of one arm of one of the chromosomes No. 1. Her mother, two sisters, and a male child of one of these two sisters presented a similar chromosomal anomaly with no expression of the syndrome. Several possible explanations are discussed.

TL;DR: This syndrome is a multisystem disorder so involvement of multiple specialists with a multimodal approach to detect and treat various manifestations at early stages will reduce the long-term sequelae and severity of the condition.
Abstract: Basal cell nevus syndrome (BCNS) or Gorlin syndrome is a rare neurocutaneous syndrome sometimes known as the fifth phacomatosis, inherited in autosomal dominant fashion with complete penetrance and variable expressivity. Gorlin syndrome is characterized by development of multiple basal cell carcinomas (BCCs), jaw cysts, palmar or plantar pits, calcification of falx cerebri, various developmental skeletal abnormalities such as bifid rib, hemi- or bifid vertebra and predisposition to the development of various tumors. BCNS is caused by a mutation in the PTCH1 gene localized to 9q22.3. Its estimated prevalence varies between 1/55600 and 1/256000 with an equal male to female ratio. The medulloblastoma variant seen in Gorlin syndrome patients is of the desmoplastic type, characteristically presenting during the first 3 years of life. Therefore, children with desmoplastic medulloblastoma should be carefully screened for other features of BCNS. Radiation therapy for desmoplastic medulloblastoma should be avoided in BCNS patients as it may induce development of invasive BCCs and other tumors in the skin area exposed to radiation. This syndrome is a multisystem disorder so involvement of multiple specialists with a multimodal approach to detect and treat various manifestations at early stages will reduce the long-term sequelae and severity of the condition. Life expectancy is not significantly altered but morbidity from complications and cosmetic scarring can be substantial.

TL;DR: The present study involved a detailed investigation of 3 cases of bifid rib, focusing on anatomical features, and classified them into 2 types, which are associated with other diseases or develop accidentally or sporadically.
Abstract: The present study involved a detailed investigation of 3 cases of bifid rib, focusing on anatomical features, and classified them into 2 types. The bifid ribs were in the right fourth rib of all 3 male cadavers. The upper intercostal spaces of the fourth bifid rib were considerably narrowed, whereas the lower intercostal spaces were widened. Although the size and shape of the bifid space between the upper and lower divisions of the bifid rib were different, the intercostal muscles were present in the bifid space in all cases. The third anterior intercostal artery from the internal thoracic artery supplied the bifid space in all cases. In 2 cases, the fourth intercostal nerve ran along the inferior margin of the fourth bifid rib and innervated the muscles of the bifid space. In the third case, there was another branch from the third intercostal nerve supplying the muscles of the bifid space as well as the fourth intercostal nerve. The bifid ribs are associated with other diseases or develop accidentally or sporadically. Knowledge of this malformation is needed for the differential diagnosis with other diseases, such as a chest wall tumor or costal fracture.
