A case of diprosopus monauchenos in a day old calf (White Fulani × Friesian cross) in an integrated dairy farm

Abstract

A rare case of ‘diprosopus monauchenos’ is reported in a newborn calf that died soon after birth. The 
‘diprosopus’ consisted of four eyes (tetraophthalmus), two pairs of nostrils, two mouths, each with a 
tongue and two pinae. The two faces were fused caudally by a single parietal bone and joined ventrally 
by the medial rhami of the mandible. It was delivered from a five year-old multipara cow. Necropsy 
revealed normal thoracic and abdominal viscera. The limbs were also normal.
