Contrast-enhanced CT findings in a dog with a wood foreign body in the vertebral canal.

Abstract

An 8-year-old Border collie was presented with progressive tetraparesis, 6 days after oropharyngeal trauma with a wooden stick. Contrast-enhanced CT of the head and the cervical spine showed heterogeneous enhancement of the soft tissues surrounding the C1 through C3 region, with extension into the ventral vertebral canal at this level. Two separate, small, foreign bodies were visible; one of which was located within the vertebral canal. Surgical exploration confirmed the presence of wooden foreign bodies within the para-vertebral soft tissues and within the vertebral canal. The dog was clinically normal 6 months postoperatively.
