It is a remnant of the embryonic YOLK SAC in which the VITELLINE DUCT failed to close.Diverticulum: A pouch or sac developed from a tubular or saccular organ, such as the GASTROINTESTINAL TRACT.Incidental Findings: Unanticipated information discovered in the course of testing or medical care. Used in discussions of information that may have social or psychological consequences, such as when it is learned that a child's biological father is someone other than the putative father, or that a person tested for one disease or disorder has, or is at risk for, something else.Encephalocele: Brain tissue herniation through a congenital or acquired defect in the skull.

The quantity and location of protruding neural tissue determines the type and degree of neurologic deficit. Visual defects, psychomotor developmental delay, and persistent motor deficits frequently occur.Diverticulum, Esophageal: Saccular protrusion beyond the wall of the ESOPHAGUS.Diverticulum, Colon: A pouch or sac opening from the COLON.Ciliary Motility Disorders: Conditions caused by abnormal CILIA movement in the body, usually causing KARTAGENER SYNDROME, chronic respiratory disorders, chronic SINUSITIS, and chronic OTITIS. Abnormal ciliary beating is likely due to defects in any of the 200 plus ciliary proteins, such as missing motor enzyme DYNEIN arms.Polydactyly: A congenital anomaly of the hand or foot, marked by the presence of supernumerary digits.Diverticulum, Stomach: Saccular, outward protrusion of all or a portion of the wall of the STOMACH.Abnormalities, MultiplePolycystic Kidney Diseases: Hereditary diseases that are characterized by the progressive expansion of a large number of tightly packed CYSTS within the KIDNEYS. They include diseases with autosomal dominant and autosomal recessive inheritance.Duodenal Diseases: Pathological conditions in the DUODENUM region of the small intestine (INTESTINE, SMALL).Diverticulitis: Inflammation of a DIVERTICULUM or diverticula.
