The paratracheal air cysts were mostly located at the right side of the trachea and at the thoracic inlet level. One-third had communication with the trachea. Paratracheal air cysts are not associated with respiratory symptoms or obstructive lung disease clinically or radiologically.
Papillary fibroelastoma is a rare benign cardiac tumor that represents 10% of all primary cardiac tumors. Diagnosis is accomplished incidentally by echocardiography that is usually performed for another purpose. Most papillary fibroelastomas are asymptomatic, but the lesions are recognized as a cause of embolisms. To the best of our knowledge, there has been no case report of computed tomography findings of a papillary fibroelastoma. We report a case of a papillary fibroelastoma in a 78-yr-old woman who had dyspnea and chest tightness. Echocardiography revealed a small lobulated mobile echogenic mass attached to the aortic valve, and CT demonstrated a lobulated soft tissue density mass with a thin stalk at the sinotubular junction of the aortic valve.
ABSTRACT:A 12-year-old intact female poodle was presented with a history of an acute episode of tenesmus and passage of ribbon-shaped stools. Anaemia, leucocytosis, hypoalbuminaemia, hyperglycaemia, and elevated ALP were found. Faecal floatation and wet mount preparation were negative for parasites. Anaerobic faecal culture resulted in a heavy growth of Clostridium. Survey abdominal radiographs revealed extensive intramural emphysema of colon and rectum. Ultrasonography of the abdomen revealed bright echoes within the layers of the colon wall, confirming the accumulation of intramural gas. Abdominal computed tomography revealed extraluminal gas tracking along the colon and the rectum. Based on the radiographic, ultrasonographic, and computed tomographic findings, the present case was diagnosed as pneumatosis coli with an underlying cause of bacterial overgrowth. The patient was treated with antibiotics for seventeen days. Clinical signs were resolved after three days of treatment. Decreased intramural gas accumulation was evident during radiography of the abdomen performed at fourteen days after the initial evaluation. Therefore, pneumatosis coli should be considered when a dog is presented with clinical signs of colitis.
Hemorrhagic fever with renal syndrome (HFRS) is an acute viral disease characterized by fever, hemorrhage and renal failure. Among the various hemorrhagic complications of HFRS, spontaneous rupture of the kidney and perirenal hematoma are very rare findings. We report here on a case of HFRS complicated by massive perirenal hematoma, and this was treated with transcatheter arterial embolization.
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.
