In 261 infants with vomiting, 11 duodenal abnormalities were diagnosed with fluid-aided ultrasound (US). These abnormalities included duodenal obstruction, malrotation with and without associated volvulus, incomplete rotation, and duodenal stenosis. US was the initial modality used in the evaluation of vomiting in these neonates and young infants. The overall sensitivity and specificity of fluid-aided US evaluation of duodenal abnormalities were 100% and 99%, respectively. (Workup bias limits the reliability of these figures.) Fluid-aided US examination of the stomach and duodenum provided a dynamic view of duodenal rotation and anatomy, and at the very least provided a method of triaging those infants who may require surgery, upper gastrointestinal series, or follow-up US to make a definitive diagnosis.
Solitary choristomas containing gastrointestinal mucosa occur rarely in the tongue and the oral mucosa and usually present as an asymptomatic mass. This report documents the occurrence of two congenital intraoral cystic choristomas in a 5-month-old male infant. The cysts were located on the dorsum of the base of the tongue and left floor of mouth anterior to the lingual cyst. Both cysts were lined by nonkeratinizing squamous epithelium and gastric, intestinal, and respiratory epithelium. The cysts were excised by an oral approach.
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.
