Radiography and ultrasonography suggested a DS; contrast\u2010enhanced computed tomography (CT) and magnetic resonance imaging (MRI) were declined. The dog presented 12\u2009months later for malodor, erythema, pruritus, focal pain on palpation, intermittent discomfort, and decreased appetite, although neurologic status remained normal. CT and MRI revealed spina bifida at T12 and a sinus tract extending from the skin to the dorsal dura mater, with mild dorsal displacement of the dura. Surgical excision via dorsal laminectomy and partial durectomy allowed en bloc removal of the tract and fibrous dural attachment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Histopathology confirmed a keratin\u2010filled dermoid cyst lined by adnexal epithelium with pyogranulomatous inflammation and a fibrous dural connection, consistent with a type V\/VI overlap DS.
