In the US and Western Europe, trauma is the fourth most common cause of death and the leading cause of death in the population less than 45 years of age [Mullinix and Foley, J Comput Assist Tomogr 28(Suppl 1):S20-S27, 2004]. Diaphragmatic injuries occur in 0.8 to 8% of patients after blunt trauma (Gray H, The muscles of the thorax. Anatomy of the human body. Lea & Febiger, Philadelphia, 1918) and may be a predictor of severity of injury in the blunt trauma patient [Worthy et al., Radiology 194(3):885-888, 1995]. The clinical diagnosis of diaphragmatic rupture (DR) is difficult and is missed in anywhere from 7 to 66% of patients [Cantwell, Radiology 238(2):752-753, 2006]. The accurate diagnosis and prognosis of this pathology depend on a complete knowledge of the clinical and radiological presentation. Computed tomography is the imaging modality of choice in the assessment of patients with clinical or radiographic findings suggestive of DR.
This pictorial essay describes the most characteristic lesions and radiologic signs of Crohn disease of the small bowel: nodular lymphoid hyperplasia, abnormal mucosal folds, villous pattern, aphthous ulcerations, linear ulcerations, cobblestone pattern, string sign, target sign, comb sign, creeping fat, sinus tracts, fistulas, and abscesses. Each description includes the definition, a correlation with the pathologic findings, an explanation of the possible physiopathologic mechanism, sample radiologic images with air enteroclysis or MDCT, the correspondence with the endoscopic findings when possible, and a list of differential diagnoses.
Gollop-Wolfgang complex is defined as the presence of a distal bifid femur and tibial hemimelia with or without hand ectrodactyly. The condition commonly presents with several skeletal abnormalities and internal organ congenital defects. We hereby report a case with a classical presentation of Gollop-Wolfgang complex.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
