Fecalith or calcification located within the appendix
Congenital absence or closure of a normal body opening or tubular structure.
Autosomal recessive condition characterized by macroglossia, exophthalmos, and gigantism, often accompanied by visceromegaly and dysplasia of the renal medulla
Closure or absence of some or all of the major bile ducts
Congenital cystic malformation of the common bile duct
Excessive development of one side or one half of the body or organ
Thickened muscle in the pylorus that prevents food from entering the duodenum
hypertrophic pyloric stenosis
Thickened by absorption, evaporation, or dehydration
Occurs when bowel prolapses into distal bowel and is propelled in an antegrade fashion
Malignant hemorrhagic tumor composed principally of cells resembling neuroblasts that give rise to cells of the sympathetic system

Located between the stomach and duodenum
Photographing the scintillations emitted by radioactive substances injected into the body; this test is used to determine the outline and function of organs and tissues in which the radioactive substance collects or is secreted
Frequently associated with sectional areas of the gastrointestinal tract; the muscle is hyperechoic, and the inner core is hypoechoic
