✓ The authors describe a case of massive pneumocephalus following ventriculoperitoneal shunting for hydrocephalus. After multiple diagnostic and surgical procedures, congenital defects in the tegmen tympani of both temporal bones were identified as the sources for entry of air. A functioning shunt intermittently established negative intracranial pressure and allowed ingress of air through these abnormalities; when the shunt was occluded, air did not enter the skull, and there was no cerebrospinal fluid leakage. Repair of these middle ear defects prevented further recurrence of pneumocephalus.

✓ A 57-year-old woman underwent ventriculoperitoneal shunt placement for noncommunicating hydrocephalus. She required several shunt revisions over a 2-year period for recurrent hydrocephalus. The shunt was subsequently found to be obstructed by growth of the saprophytic fungus, Paecilomyces variotii, an infrequent human pathogen. Paecilomyces infections have caused complications associated with prosthetic cardiac valves and synthetic lens implantation; this is the first reported association with a cerebrospinal fluid shunt.

✓ A case is reported of hydrocephalus due to overproduction of cerebrospinal fluid (CSF) caused by villous hypertrophy of the choroid plexus in the lateral ventricles. A 7-year-old girl with mental retardation developed gait disturbance; hydrocephalus and a Dandy-Walker cyst were detected on computerized tomography. She was initially treated with a ventriculoperitoneal shunt; however, shunting failed to control the hydrocephalus. The excessive outflow of CSF suggested choroid plexus abnormality, and magnetic resonance (MR) imaging revealed enlargement of the choroid plexus in both lateral ventricles. The patient was therefore diagnosed as having hydrocephalus induced by overproduction of CSF, which was controlled by resection of the choroid plexus. Histological examination showed the structure typical of normal choroid plexus. This is a rare case of villous hypertrophy of the choroid plexus in which MR imaging assisted in the diagnosis.

✓ A patient with hydrocephalus due to aqueductal stenosis suffered facial pain which was relieved after the insertion of a ventriculoperitoneal shunt. The trigeminal somatosensory evoked response (TSER) of the affected side showed lower amplitudes and longer latencies as compared to the unaffected side. Following surgery, the waves regained higher amplitudes and shorter latencies. An episode of shunt malfunction was accompanied by recurrent facial pain and impairment of the TSER. Both improved after revision of the shunt. The possible etiology of facial pain in patients with hydrocephalus is discussed.

✓ The authors describe a technique for percutaneous endoscopic shunt placement to treat clinically symptomatic spinal cysts. Seven patients underwent the procedure—five with syringomyelia, one with a symptomatic perineurial cyst, and one with a large arachnoid cyst. In all patients the shunt was successfully placed, and clinical improvement occurred in six. In four patients the entire procedure was performed endoscopically, whereas in three conversion to an open surgical exposure was required for safe access of a syrinx cavity. Overall, however, the pleural or peritoneal catheter was successfully placed endoscopically in all seven patients. There were two cases of postoperative positional headaches of which one required valve revision. In one case the catheter migrated and required repositioning. Percutaneous endoscopic shunt placement appears feasible in appropriately selected patients.

✓ The authors report three adult patients who developed a symptomatic extraaxial collection of cerebrospinal fluid (CSF) after an intracranial hemorrhage. The fluid shifted from the extraaxial into the ventricular space as the patients' symptoms progressed. The symptoms resolved after placement of a ventriculoperitoneal shunt. External hydrocephalus, which is frequently observed in children, had not yet been described in adults. It is important to differentiate chronic subdural collections from external hydrocephalus, because ventricular CSF shunting increases the former while it is the treatment for the latter. The authors believe that symptomatic extraaxial fluid collections developed in these three adults during the early phase of posthemorrhagic hydrocephalus because the ventricles presented great resistance to distention at the onset of hydrocephalus. Animal experiments have led to the same result.

Abstract Many women with cerebrospinal fluid shunts are now reaching reproductive age. Shunt malfunction may occur during pregnancy, and management requires a well-planned, combined neurosurgical and obstetrical approach. We present a case of ventriculoperitoneal shunt obstruction manifesting during the third trimester managed successfully in a conservative fashion. The literature on ventriculoperitoneal shunt malfunction during pregnancy is reviewed.

Object. The aim of this study was to analyze physiological changes in cerebrospinal fluid (CSF) dynamics following endoscopic third ventriculostomy (ETV) for shunt-dependent noncommunicating hydrocephalus. Methods. Clinical data obtained in 15 patients treated with ETV for shunt malfunction were analyzed. Magnetic resonance imaging studies demonstrated the obstruction of the ventricular system preoperatively. After ETV, the existing shunt system was removed and a continuous extraventricular drain, set at 30 cm H2O in height, was installed to measure daily amounts of CSF outflow. Cerebrospinal fluid dynamics after ETV were also evaluated using 111In-diethylenetriamine pentaacetic acid radioisotope cisternography in six of 15 patients within 1 month of the procedure. Three patients underwent cisternography at 6 months after ETV. Cisternograms were obtained at 1, 5, 24, and 48 hours after injection of the radioisotope. To study CSF absorptive capacity, ratios of radioisotope counts at 48 and 5 hours after injection were calculated (C48:C5). Seven of 15 patients had daily outflows of CSF of less than 20 ml; this volume decreased quickly within a few days. The other eight patients demonstrated an outflow of more than 150 ml of CSF for several days, three of whom had signs of transiently increased intracranial pressure. Their CSF outflow volume decreased gradually and symptoms improved within 1 week. Ratios of C48:C5 were within normal limits in five of six patients who had undergone cisternography 1 month after ETV. These ratios were decreased in all three patients who had undergone cisternography at 6 months after ETV compared with that measured at 1 month after the procedure. Conclusions. Our data suggest that CSF dynamics convert from a shunt-dependent state to a shunt-independent state within 1 week following ETV in patients with shunt-dependent noncommunicating hydrocephalus. Nonetheless, intraventricular pressure does not decrease quickly in certain cases. Cerebrospinal fluid absorptive capacity or CSF circulation through the subarachnoid space may show further improvement several months after ETV.
