“…In the previous report documenting a cat with intracranial extension of the nasal dermoid sinus, heterogeneous hyperintensity on both T1W and T2W images was observed on MRI of the head 17 . The MRI findings are similar to dermoid sinuses in the human literature, with T1W images signal intensities varying from hypo‐ to hyperintense, largely dependent on the fat content of the dermoid sinus 29,30 …”

“…17 The MRI findings are similar to dermoid sinuses in the human literature, with T1W images signal intensities varying from hypo-to hyperintense, largely dependent on the fat content of the dermoid sinus. 29,30 CSF analysis revealed a mild mononuclear pleocytosis, elevated protein concentration and a negative bacterial culture. CSF changes have not been previously reported in dogs diagnosed with dermoid sinuses in the head.…”

A 6‐year‐old, male, neutered Cavalier King Charles Spaniel dog was referred with a 4‐year history of an intermittently draining fistula on the midline of the frontal bones of the skull. Magnetic resonance imaging and computed tomography scan of the head demonstrated an extra‐axial mass in the midline between the frontal lobes, contacting the meninges and extending rostrally through a defect in the frontal bones. The mass was surgically excised via a frontal craniotomy. Histopathology of the mass demonstrated stratified squamous and keratinising epithelium with adnexal structures, consistent with the diagnosis of a dermoid sinus. Previous reports have documented dermoid sinuses in the nasal region in dogs and cats with intracranial extension. This case report documents a dermoid sinus in the frontal region with intracranial extension in a dog, confirmed by advanced diagnostic imaging, histopathology, and successfully treated surgically.
