Surgical resection of an olfactory groove meningioma using a 3D-printing technique in a dog

Abstract

A 12-year-old, spayed female, Pomeranian dog was referred for limbs stiffness and circling movement. Computed tomography(CT) and magnetic resonance imaging(MRI) revealed a contrast-enhanced space-occupying lesion suggestive of meningioma in the olfactory groove to the right frontal lobe. For a successful and accurate surgery, 3D printing technique for preoperative planning and 3D guide was applied. Surgical excision of the meningioma was successfully performed. The postoperative complications were managed through medical treatment and patient care without the revision surgery.
