✓ Obstruction of both Torkildsen and ventriculoatrial shunts by positive contrast medium injected at a previous ventriculography is reported. This complication was surgically confirmed and alleviated. Two similar cases with ventriculoatrial shunts obstructed by Pantopaque are briefly described. All cases presented symptoms of increased intracranial pressure until the contrast medium was eliminated. In cases requiring Pantopaque ventriculography, central ventriculography often permits removal of the opaque medium at the end of the examination, avoiding this complication if shunting is performed later.

✓ A technique for ventriculography using both gas and a positive contrast medium metrizamide (Amipaque) is presented. This ventriculographic method proved superior to computerized tomography (CT) scanning in revealing the cause of obstructive hydrocephalus. Small central tumors and intraventricular cysts, often missed with CT, were also well demonstrated. This technique has been used since 1975, and is simple an$ safe.

✓ The authors describe a 37-year-old man with the classic clinical features of Hand-Schüller-Christian disease. He presented with symptoms of increased intracranial pressure due to obstructive hydrocephalus secondary to a huge xanthogranuloma involving falx cerebri and tentorium cerebelli. Immunohistochemical and ultrastructural studies failed to demonstrate Langerhans histiocytes, however. The implication of this finding is discussed in light of the recent relevant literature.

✓ Two cases of aqueductal stenosis presenting with fluctuating hearing loss, tinnitus, and vertigo are presented. Audiovestibulometric assesment of both cases disclosed the characteristic pattern of disorder of the membranous inner ear. Non-tumoral aqueductal stenosis was demonstrated by computerized tomography in one case and by positive contrast ventriculography in the other. Shunting procedures of the cerebrospinal fluid resulted in resolution of inner ear dysfunction in both patients.

✓ Raised intracranial tension affects the course of tuberculous meningitis adversely. The development of hydrocephalus may account for the raised intracranial pressure. Insertion of a ventriculoatrial shunt significantly alters the course of the disease. The results in seven cases have been detailed and discussed. The levels of consciousness improved, hemiplegia and aphasia practically cleared up, and vision returned even in children who were blind for 4 to 6 weeks. Operation could be performed even in an active stage of the disease without much fear of miliary dissemination.

✓ The authors present two cases of pneumocephalus occurring in patients with permanent shunts and review nine previously reported cases. Mental status changes and headache are the most common presenting symptoms. Six of the 11 cases of pneumocephalus occurred in patients with shunt placement for hydrocephalus secondary to aqueductal stenosis. In these patients, thinned cerebrospinal fluid barriers secondary to longstanding increased intracranial pressure may predispose them to pneumocephalus. Temporary extraventricular drainage is an effective method of treatment in this group of patients. Two other etiologies are identified with significance to treatment, and the role of craniotomy is discussed.

✓ Computerized tomography (CT) has replaced pneumoencephalography and ventriculography in the diagnosis of intraventricular cysticercosis. The authors present a refinement in the use of CT by introducing a positive contrast medium into the ventricles to increase the definition of plain and contrast-enhanced scans in the diagnosis of intraventricular cysticercosis. Eleven cases of Cysticercus cyst are presented, 10 of which were precisely delineated by CT-iodoventriculography. In the remaining case, lack of definition was due to obstruction of the cerebral aqueduct. Surgical confirmation was obtained in all cases.

✓ The surgical treatment for cerebral spinal fluid (CSF) fistulas provides closure of the bone and dural defects and prevents the recurrence of brain herniation and CSF fistula. The two main approaches used are the transmastoid and middle fossa ones. The authors review the results of performing a modified middle fossa approach with a vascularized temporalis muscle flap to create a barrier between the repaired dural and bone defects. Fifteen consecutive cases of CSF fistulas treated at the authors' institution were retrospectively reviewed. All patients presented with otorrhea. Eleven patients had previously undergone ear surgery. A middle fossa approach was followed in all cases. The authors used a thin but watertight and vascularly preserved temporalis muscle flap that had been dissected from the medial side of the temporalis muscle and was laid intracranially on the floor of the middle fossa, between the repaired dura mater and petrous bone. The median follow-up period was 2.5 years. None of the patients experienced recurrence of otorrhea or meningitis. There was no complication related to the intracranial temporalis muscle flap (for example, seizures or increased intracranial pressure caused by muscle swelling). One patient developed hydrocephalus, which resolved after the placement of a ventriculoperitoneal shunt 2 months later. The thin, vascularized muscle flap created an excellent barrier against the recurrence of CSF fistulas and also avoided the risk of increased intracranial pressure caused by muscle swelling. This technique is particularly useful in refractory cases.

✓ A newborn infant with a posterior fossa subdural hematoma is described, and nine similar cases from the literature summarized. A postnatal asymptomatic period was followed by signs of increased intracranial pressure. The diagnosis was established on the basis of negative subdural taps, bloody or xanthochromic ventricular fluid under increased pressure, and demonstration of a posterior fossa mass on the ventriculogram. Surgical evacuation with careful observation for an associated intracerebellar hematoma is the treatment of choice. Five of the 10 cases developed postoperative communicating hydrocephalus.
