Trapped Fourth Ventricle

Object Trapped fourth ventricle (TFV) is a rare late complication of postinfectious or posthemorrhagic hydrocephalus. This entity is distinct from a large fourth ventricle because TFV entails pressure in the fourth ventricle and posterior fossa due to abnormal inflow and outflow of CSF, causing significant symptoms and signs. As TFV is mostly found in children who were born prematurely and have cerebral palsy, diagnosis and treatment options are a true challenge. Methods Between February 1998 and February 2007, 12 children were treated for TFV in Dana Children's Hospital by posterior fossa craniotomy/craniectomy and opening of the TFV into the spinal subarachnoid space. The authors performed a retrospective analysis of relevant data, including pre- and postoperative clinical characteristics, surgical management, and outcome. Results Thirteen fenestrations of trapped fourth ventricles (FTFVs) were performed in 12 patients. In 6 patients with prominent arachnoid thickening, a stent was left from the opened fourth ventricle into the spinal subarachnoid space. One patient underwent a second FTFV 21 months after the initial procedure. No perioperative complications were encountered. All 12 patients (100%) showed clinical improvement after FTFV. Radiological improvement was seen in only 9 (75%) of the 12 cases. The follow-up period ranged from 2 to 9.5 years (mean 6.11 ± 2.3 years) after FTFV. Conclusions Fenestration of a TFV via craniotomy is a safe and effective option with a very good long-term outcome and low rate of morbidity.

✓ There is no consensus as to the optimum management of patients who harbor cysticercal cysts within the fourth ventricle. Compared with the alternative treatment options of anthelmintic medication and/or cerebrospinal fluid shunt placement, the surgical removal of the cyst has the advantage of eliminating the inflammatory nidus and potentially obviating the need for a complication-prone shunt. Here, an endoscopic surgical approach is described and proposed as an alternative to the standard suboccipital craniectomy for removal of cysticercal cysts within the fourth ventricle.A retrospective analysis of five consecutive endoscopic cases was performed. Endoscopic removal of all cysts within the fourth ventricle was successful in each case. The mean length of operative time was short and blood loss was insignificant. The endoscopic procedure was safe and associated with minimal postoperative discomfort in most patients.In properly selected patients, the endoscopic removal of cysticercal cysts located within the fourth ventricle should be considered as the primary treatment for this condition.
