title: [A case of diprosopus in the cat].
abstract: A case of diprosopus in a spontaneously delivered live-born kitten is reported. All facial components were completely duplicated. Fusion of the skulls had occurred in the temporal region; a single ear was present at the site of fusion. Additional defects were a cleft lip in one face and cleft palates in both faces. The cerebral hemispheres and arterior portions of the brain stem were completely duplicated, whereas the cerebellum and caudal brain stem were partially duplicated. The pathogenesis and aetiology are discussed. It is believed that disprosopus originates during the (pre)gastrulation stage of embryonic development, either by coalescence of two embryonic fields following a double process of gastrulation or by bifurcation of the axial mesoderm during a single gastrulation.
