RESUMO
La duplicación cráneo-facial (diprosopus) es el resultado de la forma menos común de gemelos acoplados. La utilización de la ecografía 3D para el diagnóstico de esta patología ha sido reportada. Se presenta el segundo caso de esta patología en Colombia. Caso clínico de hijo de madre de 28 años a quien se le realizó diagnóstico prenatal con ecografía 3D, de duplicación craneofacial y de la columna vertebral. Cariotipo prenatal bandeo G: 46, XX. Al nacimiento se encontró feto de sexo femenino con duplicación craneofacial con la presencia de tres ojos, dos narices y dos bocas, con presencia de columna vertebral duplicada hasta la región cervical con espina bífida a nivel cervical. La utilización de ecografía 3D, permite realizar un diagnóstico oportuno de esta patología, lo que permite un abordaje multidisciplinario de las gestantes(AU)
Craniofacial duplication (diprosopus) is the result of the less common form of coupled twins. The use of 3D ultrasound for diagnosis of this disease has been reported.A second case of this disease occurs in Colombia. A clinical case of a son of 28-year-old mother, who underwent prenatal diagnosis with 3D ultrasound of craniofacial duplication and spine.Prenatal karyotype banding G: 46XX. At birth, a female fetus was found with craniofacial duplication, the presence of three eyes, two noses and two mouths, the presence of duplicate backbone up to the cervical region, and spina bifida at the cervical level. The use of 3D ultrasound allows early diagnosis of this disease, allowing a multidisciplinary approach of pregnant women(AU)

This work describes a malformation in one newborn female bovine, with two faces and two skull fused, showing one single head. Duplications of the nasal and oral structures, tetraofthalmy, two brains, one single cerebellum, and pons were observed. The right thyroid was hypertrophic and the other organs had normal morphology. Every change observed in this case was compatibles with diprosopus.

Congenital malformations with multiple anomalies have been described infrequently in the veterinary literature. A stillborn male crossbred lamb with diprosopus, craniorachischisis, and arthrogryposis was examined macroscopically and histopathologically in this study. The left head was smaller than the right head. Micrencephaly, agnathia, and a rudimentary tongue, which was adherent to the palate, were present in the left head. Micrencephaly, brachygnathia superior, and cleft palate were present in the right head. Cerebellar agenesis and spinal cord hypoplasia were observed. The cerebrums and the spinal cord were covered with a tapering membranous structure. Neural and dermal tissues were noted to intervene upon microscopic examination of this structure. Disorganization of neurons was observed in both cerebrums, though it was more severe in the left one. This case demonstrates many congenital defects occurring together in a lamb.
