[Choanal atresia in an alpaca cria (Vicugna pacos)]

After birth, an alpaca cria was noticed to exhibit weakness and respiratory distress, particularly when attempting to suckle milk from the dam's udder. Clinical findings indicated the presence of bilateral choanal atresia and the animal was subsequently euthanised. A computed tomography scan and a pathological examination were performed to describe the malformation in detail. Choanal atresia is a common malformation in neonatal South American camelids, surgical treatment is not recommended. This case report provides an overview of the clinical findings as well as the results of imaging and pathologic examinations and may help to raise awareness of this malformation for early recognition.
