56. Transcerebellar VP shunt for arachnoid diverticulum in the fourth ventricle of a dog

Transcerebellar ventriculoperitoneal shunt for management of presumed arachnoid diverticulum in the fourth ventricle of a dog https://pubmed.ncbi.nlm.nih.gov/38519... 1: A dog is presented with acute onset, progressive, left-sided central vestibular syndrome. Initial MRI reveals marked dilation of all ventricles. What was the initial surgical intervention performed? a) Craniotomy with cysto-peritoneal shunting b) Ventriculoperitoneal shunting from the left lateral ventricle c) Transcerebellar ventriculoperitoneal shunting d) Suboccipital craniectomy, durotomy, diverticulectomy, and marsupialization 2: What was the presumed diagnosis of the cyst-like lesion found in the fourth ventricle of the dog 18 months after the first surgery? a) Choroid plexus tumor b) Epidermoid cyst c) Arachnoid diverticulum d) Ependymoma 3: What surgical technique was used to address the presumed arachnoid diverticulum in the fourth ventricle during the second surgery? a) Craniotomy with cysto-peritoneal shunting b) Ventriculoperitoneal shunting from the left lateral ventricle c) Transcerebellar ventriculoperitoneal shunting d) Suboccipital craniectomy, durotomy, diverticulectomy, and marsupialization 4: According to the case report, what was a potential complication that the dog experienced after the second surgery, and was likely due to iatrogenic trauma? a) Shunt obstruction b) Vestibular-cerebellar ataxia c) Cranial nerve dysfunction d) Intra-cystic hemorrhage
