Choanal atresia

Choanal atresia (CA) is a congenital anomaly of the posterior nasal airway characterized by the obstruction of one (unilateral) or both (bilateral) choanal aperture(s), with clinical manifestations ranging from acute respiratory distress to chronic nasal obstruction.

Accessory spleen

An accessory spleen is a round, iso-echogenic, homogenic and smooth structure and is seen as a normal variant mostly on the medial contour of the spleen, near the hilus or around the lower pole. This has no pathogenic relevance.

	Report of a fourth individual with a lethal syndrome of choanal atresia, athelia, evidence of renal tubulopathy, and family history of neck cysts.
	Horvath GA, Armstrong L. Am J Med Genet A. 2007;143A(11):1231-5.
	Variably present features were choanal atresia, preauricular tags and pits, branchial clefts, ventricular septal defect, type IIB interrupted aortic arch, pulmonary lobation anomaly, absent gallbladder, absent thymus, absent parathyroid gland, accessory spleen, and imperforate anus.
