I would say the first is a " dicephalus thoraco-conjoined twin" (did you checked if there were also internal malformations like two hearts or two alimentary tracts etc?) and the second is "arachnomelia" (did also had facial deformities?).

Exceptional pictures !

Thank yu Davide, Thank you Maurizio for your help

Could you please support your suggestion with references (Books or References), especially the tunisian one.

Thank you again

Ali

The first one is thoracopagus bicephalus and the second is arthrogriposis congenita. But the second can be schistosomus reflexus

Hello Ali,

Dear Dr. Ali: The morphological appearence of the limbs particularly at the level of tarsal-metatarsal joints suggest some kind of osteogenesis imperfecta (http://www.ncbi.nlm.nih.gov/pubmed/26542481) so I suggest this condition must be considered in your differential diagnosis in figure 2. In Schistosomus reflexus there is not hip formation (It is not the case as seen in figure 2) excepting this were a different type of the disease.

Hi Colleagues,

I here attached additional figure for a fetal anomaly in camel, it was founded in a case of dystocia in our camel clinic. Is this a case of hydrocephalus.

For such anomalies (figure 1, 2, 3), how would be they developed, I mean the pathogensis? Is figure 1 was one egg incompletely divided?

Thank you for your help and contributions.

Hi Ali

the first one is double head, but as my college said you have to check internal organs, the second is arthrogryposis of the distal joints. For me not shistosoma ref. because we can not see internal organ at the outside, the legs are at the normal place they did not return back right to lumbar region with the head.

With my best regards

Thank you Davide

Dear Dr. Ali:

Number 1: Fetus dicephalus

Number 2. It should be Arachnomelia. Please see the article by Gentile and Testoni published in Slov Vet Res 2009; 43:17-29 (page 23)(http://www.arcangelogentile.it/Files/Lavori_Scientifici/Slovenian%20veterinary%20Research.pdf).

Best Regards,
