We report the computed tomographic and angiographic findings in the case of a recently obtained successful clinical outcome after embolization of the hepatic artery in the case of a snakebite causing hemoperitoneum associated with hepatic necrosis and rupture with active bleeding.
Calcifying aponeurotic fibroma is a rare soft tissue tumor that occurs in the distal extremities of children and adolescents. We report ultrasound and X-ray findings of a calcifying aponeurotic fibroma in the finger of a 36-year-old woman, associated with distal phalangeal bone involvement.
PURPOSE: Chemical ablation of the gallbladder may be a useful alternative to surgery for inoperable disease. The purpose of this study was to investigate the feasibility of chemical ablation of the gallbladder with acetic acid in a canine model.
MATERIALS AND METHODS:Five beagle dogs underwent percutaneous transhepatic cholecystostomy. Percutaneous occlusion of the cystic duct was performed with use of n-butyl cyanoacrylate (NBCA) and coils. After confirmation of occlusion of the cystic duct, sclerotherapy of the gallbladder was performed with 4 -7 mL of 50% acetic acid through the drainage catheter. Acetic acid was retained for 20 minutes with intermittent position change. The drainage catheter was removed immediately after sclerotherapy. The dogs were euthanized 8 weeks after the procedure. The gallbladders and adjacent organs were evaluated grossly as well as microscopically.RESULTS: All dogs survived without serious complications during the experimental period. Sclerotherapy was technically successful in all dogs. Gross specimens of the gallbladder showed shrinkage and fibrotic change without retention of any bile, mucus, or pus. Histologic examinations from the body and fundus of the gallbladder demonstrated complete ablation of the mucosa. However, the neck region of the gallbladder near the cystic duct, where NBCA and coils for cystic duct occlusion were located, had focal areas of remnant or regenerating mucosa.CONCLUSIONS: Chemical ablation of the gallbladder with 50% acetic acid was effective and safe. Complete ablation was achieved in the majority of gallbladder mucosa except for a small portion located in the gallbladder neck.
ObjectiveWe observed patients in whom the fluid collection in the right lateral portion of the superior aortic recess on computed tomography (CT) scans mimicked a right anterior mediastinal mass on chest PA radiographs. The purpose of this study was to assess chest PA and CT features of these patients.Materials and MethodsAll chest PA radiographs and CT scans in 9 patients were reviewed by two radiologists on a consensus basis; for the presence of pleural effusion, pulmonary edema and heart size on chest PA radiographs. For the portion of the fluid collection in the superior aortic recess (SAR), a connection between the right lateral portion of the SAR (rSAR) and posterior portion of the SAR (pSAR) on CT scans, and the distance between the right lateral margin of the rSAR and the right lateral margin of the superior vena cava.ResultsFluid collection in the rSAR on CT scans caused a right anterior mediastinal mass or a bulging contour on chest PA radiographs in all women patients. All patients showed cardiomegaly, five patients had pleural effusion, and two patients had mild pulmonary edema. Further, eight patients showed a connection between the rSAR and the pSAR.ConclusionThe characteristic features of these patients are the right anterior mediastinal mass-like opacity due to fluid collection in the rSAR, are bulging contour with a smooth margin and cardiomegaly regardless of pulmonary edema on the chest PA radiographs, and fluid connection between the rSAR and the pSAR on CT scans.
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.
