We conclude that a double layered border in univesicular and double layered internal septum in multivesicular pulmonary echinococcal cysts is a reliable indicator of pulmonary echinococcosis, with a specificity of 66 % and 100 %, respectively.
Teratoma is a germ cell tumour which accounts for approximately 15-20 % of all ovarian cancers. The tumour is possibly derived from ectodermal differentiation of totipotent cells or mitotic germ cells. We present a case of a 37-year-old female patient with multiple spherical structures floating in a large pelvic-abdominal cystic mass seen on sonographic images. A giant echinococcal cyst gravid with its daughters was the presumed preoperative sonographic diagnosis. The patient underwent excision of the lesion, and the pathological diagnosis was teratoma. The striking feature of multiple spherical structures in the cyst was caused by multiple spherules of a mature ovarian cystic teratoma which were representing numerous mobile sebaceous cysts and desquamative keratin formations.
The use of non-invasive imaging techniques to rapidly establish diagnosis has always been an attempt in emergency situations. Recent significant advances in imaging technology have changed approach and algorithm of many emergencies. We present a case of swallowed date stone resulting in duodenal obstruction in a 10-year old child. Following the suspicion of a foreign body impaction which caused symptoms of acute intestinal obstruction, the case was diagnosed precisely by conventional sonography. This spared the patient the laparotomy scheduled initially. Instead, endoscopic removal of the date stone was accomplished successfully with smooth recovery.
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.
