Identification of an intra-cranial intra-axial porcupine quill foreign body with computed tomography in a canine patient

An intra-cranial intra-axial foreign body was diagnosed in a golden retriever dog through the use of computed tomography (CT). Confirmed by necropsy, a porcupine quill had migrated to the patient's left cerebral hemisphere, likely through the oval foramen. This case study demonstrates the efficacy of CT in visualizing a quill in the canine brain.
