Abstract An 18-year-old woman presented during the 2nd month of her pregnancy with noncommunicating hydrocephalus due to a cerebellar hemangioblastoma. The tumor rapidly enlarged over a 12-day period after ventriculoperitoneal shunting, probably because of expansion of the vascular compartment. Serial computed tomography and magnetic resonance imaging observations support previous speculations in the literature that vascular engorgement of hemangioblastomas probably accounts for the rapid deterioration of some patients during pregnancy.

Abstract OBJECTIVE Endoscopic third ventriculostomy has developed into a therapeutic alternative to shunting for the management of carefully selected patients with primarily noncommunicating hydrocephalus. This procedure, however, requires a general anesthetic and necessitates violation of the brain parenchyma and manipulation near vital neural structures to access the floor of the third ventricle. Using two cadavers and off-the-shelf angiographic catheters, we sought to determine whether it was possible to navigate a catheter, angioplasty balloon, and stent percutaneously through the subarachnoid space from the thecal sac into the third ventricle so as to perform a third ventriculostomy from below. METHODS Using biplane angiography and off-the-shelf angiographic catheters along with angioplasty balloons and stents, we were able to pass a stent coaxially from the thecal sac to and across the floor of the third ventricle so as to achieve a third ventriculostomy from below. RESULTS Coaxial catheter techniques allowed for the percutaneous insertion of a stent across the floor of the third ventricle. Ventriculostomy was confirmed by injecting contrast medium into the lateral ventricle and seeing it pass through the stent and into the chiasmatic cistern. CONCLUSION We describe the performance of third ventriculostomies in two cadavers by use of the new concept of percutaneous intradural neuronavigation. This procedure may obviate the need for general anesthetic and minimize the potential for brain and vascular injury, especially if ultimately combined with magnetic resonance fluoroscopy.

Ventricular Filling

Radionuclide lumbar cisternography using indium 111-diethylenetriamine pentaacetic acid (111 In-DTPA) and a mobile γ-camera with a converging collimator was utilized as a bedside procedure to evaluate CSF dynamics and the patency of the cerebral ventricular system in 30 preterm infants with hydrocephalus. Serial images of the brain were obtained at 0, 1, 2, 6, 24, and 48 hours after instillation of the isotope in the lumbar subarachnoid space. Three distinct patterns were seen. Infants with posthemorrhagic hydrocephalus displayed prompt ventricular filling but markedly delayed emptying with minimal flow over the cerebral convexities. Infants with ventriculomegaly secondary to suspected brain atrophy or periventricular leukomalacia demonstrated a pattern of prompt ventricular filling, delayed emptying, but with flow present over the convexities. An infant with noncommunicating hydrocephalus secondary to an Arnold-Chiari malformation showed a pattern of complete obstruction with no ventricular filling. Radionuclide lumbar cisternography appears to be a safe, well-tolerated procedure which produces images of sufficient resolution to provide valuable information about CSF dynamics, delineating basal cisternae, ventricles, and subarachnoid flow paths.

Noncommunicating Hydrocephalus

Cerebrospinal fluid (CSF) is produced at a constant rate in the choroid plexuses of the lateral and third ventricles, and it predominately drains through the Sylvius aqueduct to the fourth ventricle. If the Sylvius aqueduct becomes obstructed, such as caused by a growing tumor adjacent to it, CSF accumulates in the ventricles and the ventricles expand significantly, leading to a medical condition known as noncommunicating, hydrocephalus.

Prompt Diagnosis

Object The prognosis for intraventricular neurocysticercosis (IVNCC) is poorer than that for parenchymal NCC, making prompt diagnosis and treatment especially important. Although active, viable intraventricular cysts produce no reaction in the host; they can cause noncommunicating hydrocephalus, the onset of which is frequently abrupt. With the death of the larva comes a local granulomatous ependymitis, generalized ventriculitis, and meningoencephalitis. The authors report on 18 patients with IVNCC (accrued from a larger case series of 62 patients with NCC treated over an 11-year period), detailing clinical presentation, neuroimaging findings, treatment, and outcome. Methods All patients presented with hydrocephalus and/or meningitis. The most valuable diagnostic tests were magnetic resonance imaging of the brain and EITB of serum and/or cerebrospinal fluid. Treatment included albenda-zole and steroid therapy in all cases, and when necessary in cases requiring urgent or emergency ventriculostomy and/or surgical removal of the obstructing cyst (followed by shunt placement if indicated). Conclusions An extensive review of the literature on IVNCC has been prepared, with the goal of providing the reader with the information necessary to diagnose and treat this complex and potentially fatal disease in a timely and effective manner.

✓ The authors present a case of secondary amenorrhea in a 32-year-old woman found to have noncommunicating hydrocephalus due to aqueductal stenosis. Although the presentation of hydrocephalus with amenorrhea has been previously reported, this association remains rare. After treatment via endoscopic third ventriculocisternostomy, the patient resumed normal menstruation and all hormonal abnormalities have resolved except hypothyroidism. A review of the literature on the etiology of endocrinological disturbances in patients with hydrocephalus is presented.
