A 4-year-old Border collie was presented with one episode of collapse, altered mentation, and a suspected pharyngeal stick injury. Magnetic resonance imaging (MRI) and computed tomography showed a linear foreign body penetrating the right oropharynx, through the foramen ovale and the brain parenchyma. The foreign body was surgically removed and medical treatment initiated. Complete resolution of clinical signs was noted at recheck 8 weeks later. Repeat MRI showed chronic secondary changes in the brain parenchyma. To the authors' knowledge, this is the first report of the advanced imaging findings and successful treatment of a penetrating oropharyngeal intracranial foreign body in a dog., (© 2017 American College of Veterinary Radiology.)

An 8‐year‐old Maltese dog was referred for surgery due to an intracranial foreign body. The dog had been hit by a car and had experienced three generalised tonic‐clonic seizures. Examination by computed tomography revealed an intracranial metallic object oriented in a vertical direction. The ventral end protruded by 2 mm, in close proximity to the temporomandibular joint. Furthermore, moderate bilateral ventricular dilatation was observed. During the surgery, object removal was initially attempted via the oral cavity, but due to deep coverage by the neighbouring tissues, a rostrotentorial craniotomy was subsequently chosen to remove the foreign body from the brain. The foreign body was identified as a sewing needle. Postoperative computed tomography revealed that the intracranial part of the needle had been removed completely, leaving only the extracranial part, which had become detached from the rest of the needle. Antiepileptic drugs have been continued postoperatively, and the dog is currently symptom‐free. [ABSTRACT FROM AUTHOR]
