A rare case of diprosopus, tetraophthalmus and meningoencephalocele in A lamb

Üç yaşlı Sakız ırkı bir koyundan güç doğumla doğan iki yüzlü, ölü, dişi bir kuzu tanımlandı. İki yüz tek bir gövde üzerine oturmuş, oksipital bölge ile kısmen parietal ve temporal bölgelerden kaynaşmıştı. Her iki yüzde iki göz, birer kulak, normal gelişmiş ağız boşluğu ancak tek bir laringofarinks ve özofagus vardı. Hiperemik ve gevşek zar benzeri bir doku hatalı şekillenmiş frontal ve parietal kemiklerden dışarı çıkmıştı. Kosta kondral eklemler gelişmemişti; başka bir iskelet anomalisi görülmedi. Zarsal dokunun mikroskobik muayenesinde çoğunlukla otolitik nöronlara rastlandı. Yetersiz kafatası gelişimi, meningoensefalosel ile beraber olan ve nadir karşılaşılan diprosopus olgusundan dolayı, bu olgunun sunumu yapıldı.

Bir kuzuda nadir rastlanan diprosopus, tetraophthalmus ve meningoensefalosel olgusu

A female, dystocic, two-headed dead lamb from a 3-year old Sakiz sheep is described. The two faces of the foetus fused at occipital, partly parietal and temporal bones on a single trunk. On each face there were two eyes, one ear and one normally developed oral cavity with only one laryngopharynx and oesophagus. A fl accid, hyperemic, membrane-like tissue protruded from the defective frontal and parietal bones. There were no other skeletal abnormalities but incomplete costal articulation. Microscopic examination of the membranous tissue revealed mostly autolytic neurons. Since diprosopus cases with defective skull development and meningoencephalocele are rare events, this case was evaluated for presentation.
