Plain-English summary
A 6-month-old male bloodhound-Rhodesian ridgeback mix was brought in for a mass on his back that was suspected to be a dermoid sinus, a type of skin abnormality. A 2.5-year-old male Rhodesian ridgeback also had a similar mass on his neck. Both dogs underwent a special type of X-ray called a CT scan to help the vet understand the problem better before surgery. The scans showed that the masses were connected to the spinal cord, and both dogs had successful surgeries to remove the dermoid sinuses. They both recovered well without any complications.

Abstract
A 6 mo old male castrated bloodhound-Rhodesian ridgeback mix (case 1) presented for a mass suspected to be a dermoid sinus in the thoracolumbar region, and a 2.5 yr old male castrated Rhodesian ridgeback (case 2) presented for a mass suspected to be a dorsal cervical dermoid sinus. Both dogs underwent single-phase contrast computed tomography (CT) to characterize the extent of the dermoid sinus prior to surgical excision. Soft tissue and bony abnormalities of the vertebral spine associated with the dermoid sinuses were confirmed in both dogs prior to surgery, demonstrating communication with the dura of the spinal cord. Surgical exploration and excision of the dermoid sinus was performed in each dog, including partial laminectomy. Both cases had resolution of the sinus and an uncomplicated recovery. These cases show that single-phase contrast CT was accurate in characterizing the extent of the dermoid sinus without adjunctive tests or more invasive diagnostics. Single-phase contrast CT should be considered as a preoperative method to characterize the extent of dermoid sinuses, avoiding the risks associated with myelography or fistulography and the expense of MRI. This is also the first report of a dermoid sinus in the thoracolumbar region and the first in a bloodhound and Rhodesian ridgeback mix.
