Rhabdomyosarcoma is a common paediatric soft tissue tumour. However, the anterior mediastinum is an extremely rare site for its occurrence. This report describes the imaging and histological findings of such a tumour in a 4-month-old boy.
Fracture-separation of the distal humeral epiphysis is a rare condition known to be associated with non-accidental injury. Ultrasound is useful in diagnosis of this important disease entity with the humeral epiphysis not yet ossified.
Objectives: Reduced physical activity and muscle atrophy is common in patients with femur fracture. The aim of this study is to assess whether immobilization after femur fracture surgery leads to atherosclerotic change in popliteal arteries. Methods: Thirty one patients who admitted for rehabilitation after surgical treatment of femur fracture (13 men and 18 women; mean age, 77611 years) were enrolled. We measured intima-media thickness (IMT) of popliteal artery in longitudinal and transverse plane bilaterally using ultrasound. And peak systolic velocity (PSV) was also evaluated by duplex-sono. Results: Interval between fracture and exam was 67660 days and 6 patients were taken total hip arthroplasty (including hemi-arthroplasty) and 25 patients were treated by internal pin fixation. Mean IMT of popliteal artery was thicker in the fracture side than in the non-fracture side (1.2160.90 mm vs 0.9360.68 mm) significantly (pp..05). However, PSV was increased significantly (102.2613.6 cm/s vs 94.664.9 cm/s) in patients with 1 month or more duration. Femur fracture and consequential immobilization affected popliteal artery IMT, and it was highly related to progression of atherosclerotic plaque formation. Conclusions: Femur fracture and consequential immobilization affected popliteal artery IMT, and it was highly related to progression of atherosclerotic plaque formation.
Early diagnosis of life-threatening Fournier's gangrene, a rare surgical emergency, is essential. Detection of gas within the swollen scrotal skin by ultrasonography (US) is of great help in patients with equivocal physical examination findings.
this rare entity. We wish to highlight the fact that in our series, the presentation, clinically mimicked endometriosis. Conclusions: TGC can mimic endometriosis in females. TV sonography is a valuable tool in correctly identifying TGC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations 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.
