The incidence of clinically significant radiation-induced cholecystitis was only 0.8% despite a high prevalence of gallbladder imaging abnormalities after (90)Y radioembolization. Therefore, in the postinterventional care of patients with abdominal pain after (90)Y radioembolization, even if imaging abnormalities of the gallbladder are identified, cholecystectomy should be reserved for patients in whom other causes of pain have been excluded.
The antenatal detection of a large posterior cystic neck mass and a poorly defined or nonvisualized cerebellar vermis suggest Dandy-Walker malformation with a herniated cyst. Three-dimensional sonography and fetal MRI are important adjunctive methods that can be used to evaluate the herniation site and a possible neuronal migrational disorder.
Müllerian adenosarcoma is a rare neoplasm that can arise in both uterine and extrauterine locations. This report describes the ultrasound and magnetic resonance imaging findings of one case of ovarian adenosarcoma and reviews the literature as to the previously described imaging findings. Adenosarcoma should be considered in patients with a predominantly solid pelvic mass on imaging, particularly in those with a history of endometriosis or findings compatible with endometriosis on ultrasound or magnetic resonance imaging. A very low resistive index on ultrasound may also be suggestive of this diagnosis.
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.
