AB  - Isolated fourth ventricle is an untoward but interesting complication caused by 
      the shunt procedure, which has been recognized since the introduction of CT 
      scanning. Auditory brain stem evoked potentials (BAEPs) were recorded in a 
      patient with isolated fourth ventricle for assessment of brain stem function. 
      Case 1. A 9-year-old boy. He had undergone repair of the lumbosacral meningocele 
      at birth, followed by shunting procedures, including repeated shunt revision, for 
      hydrocephalus which subsequently developed. CT scanning on admission revealed 
      typical findings of isolated fourth ventricle, while neurological examination 
      disclosed no abnormalities. BAEPs on admission revealed normal waves both in 
      amplitude and latency. This patient has been doing well without further shunting 
      procedures. Case 2. A 17-year-old male was admitted with complaints of headache, 
      diplopia, nystagmus and ataxic gait. He had a history of operation for radical 
      removal of cerebellar astrocytoma and lateral ventriculo-peritoneal shunt at 9 
      years of age. CT scanning on admission revealed a typical isolated fourth 
      ventricle, and fourth ventricle-peritoneal shunt was performed. Postoperative 
      serial BAEPs revealed gradual improvement of brain-stem function. Clinically he 
      has been symptom-free thereafter except for slight nystagmus. Case 3. A 
      2-year-old female suffering from hydrocephalus developed after neonatal 
      intraventricular hemorrhage and ventriculitis. After repeated revision of a 
      lateral ventriculo-peritoneal shunt, she was admitted in semicoma with vomiting 
      and opisthotonic posture. CT study revealed an isolated fourth ventricle and 
      preoperative BAEPs showed marked abnormalities. Although fourth 
      ventricle-peritoneal shunt was performed, no remarkable change in BAEPs was 
      obtained, and neurological deficit of considerable degree persisted.(ABSTRACT
