Transverse Dorsal Presentation.
This fetus is in a transverse dorsal presentation and in left cephalo-ilial position. The presentation need not be symmetrical as shown in this drawing. It may be difficult to determine whether the head is near the left or the right ilium of the mare. All one may be able to palpate is the curvature of the back. This is a rare presentation. The head and the front legs are in one horn, the hindlegs in the opposite horn.
