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.
