Abstract

A captured Japanese wild boar (Sus scrofa leucomystax) fetus was dicephalic. The fetus had two heads, but one body from the cranial neck region. Computed tomography imaging revealed that the two crania merged at the occipital bone, and the vertebral bodies between the atlas and the seventh thoracic vertebra were deformed. The fetus was found to have two tongues and laryngopharynges, but its esophagus and trachea were not duplicated. Each head contained a cerebrum and cerebellum, but the brains merged at the obex of the medulla oblongata, and the cervical spinal cord had duplicated ventral clefts. The heart was composed of three atria and four ventricles. This is the first report of a dicephalus with cardiac malformation in a wild boar.

摘要

一只捕获的日本野猪（野猪指名亚种）胎儿为双头畸形。该胎儿有两个头，但从颅颈区域起是一个身体。计算机断层扫描成像显示，两个颅骨在枕骨处融合，第一颈椎和第七胸椎之间的椎体变形。发现该胎儿有两条舌头和两个喉咽，但食管和气管未重复。每个头部都包含一个大脑和小脑，但大脑在延髓闩处融合，颈脊髓有重复的腹侧裂。心脏由三个心房和四个心室组成。这是野猪双头畸形伴心脏畸形的首例报告。
