Dermoid sinus in a crossbred Rhodesian ridgeback dog involving the second cervical vertebra.
A 4-year-old neutered Rhodesian ridgeback/dalmatian crossbred bitch was presented with a cervical, dorsal midline cutaneous swelling after 2 unsuccessful attempts at surgical resection of a dermoid sinus. Radiographs of the cervical spine indicated a C2 transosseous communication with the vertebral canal. Ultrasonographic evaluation demonstrated 2 interlinking cavities terminating close to C2. Complete resection of the sinus tract necessitated a partial dorsal laminectomy. Histology confirmed the diagnosis. This case is compared to similar cases in the literature.
