A 59-year-old man with history of multiple sclerosis and residual sensory and motor dysfunction presented with progressive lower-extremity weakness, ataxic gait, and intermittent urinary incontinence. Brain MRI demonstrated volume loss with disproportionate ventricular dilatation, but no evidence of infarction or abnormal enhancement. Radionuclide cisternography showed early and persistent ventricular reflux, poor progression of radiopharmaceutical over convexities, and delayed clearance in a pattern consistent with normal pressure hydrocephalus...

Although new MR imaging techniques can provide high-resolution information on CSF dynamics and are not associated with ionizing radiation, SPECT/CT cisternography is a valuable alternative for those with contraindications to MR imaging. SPECT/CT cisternography combines functional and anatomic imaging to provide accurate and detailed information on CSF distribution to be used in conjunction with clinical findings for the diagnosis and evaluation of NPH, as illustrated in this case report.

We identified factors that predict the disappearance of the triad of symptoms (gait disturbance, cognitive impairment and urinary incontinence) of idiopathic normal pressure hydrocephalus (iNPH) following shunt surgery in this study. We classified 71 patients with iNPH into those whose objective symptoms disappeared (disappearance group) or remained (residual group), for each of the triad symptoms 12 months after shunt surgery. Logistic regression analyses were used to identify the predictors of the disappearance of symptoms among 10 variables before shunt surgery (e...

We describe a patient with an intraspinal paraganglioma who presented with normal pressure hydrocephalus. A 70-year-old man presented with a 6-month history of gait disturbance and cognitive dysfunction. Computed tomography of the brain and magnetic resonance imaging of the spine revealed communicating hydrocephalus and a spinal mass at the T12-L1 level which proved to be a paraganglioma of the filum terminale. Radioisotope cisternography revealed a severe delay in cerebrospinal fluid circulation. Symptoms related to communicating hydrocephalus resolved after tumor resection...

A 67-year-old woman developed gait disturbance, dysarthria, cognitive impairment and incontinence at age 65, and became bedridden. She showed mutism, stupor and lower limb spasticity. Cranial CT and MRI revealed marked ventricular enlargement and a cerebellopontine angle tumor. CSF study showed normal pressure (125 mmH2O) and elevated protein (143 mg/dl). Radionuclide cisternography showed redistribution of radionuclide to the ventricles and intraventricular residual radionuclide after 72 hours, which allowed a diagnosis of normal pressure hydrocephalus...

Spontaneous intracranial hypotension (SIH) is characterized by severe postural headache and low cerebrospinal fluid (CSF) pressure. Radionuclide cisternography (RC) is of some value in diagnosing CSF leakage causing SIH. However, the sensitivity of RC is too low to demonstrate the site of leakage. In these cases, the early appearance of the radioactivity in the urinary bladder has also been used as an indirect finding in the diagnosis of SIH. The aim of this study was to evaluate the diagnostic reliability of early urinary bladder activity as an indirect sign of SIH...

We studied retrospectively the effectiveness of the repeated lumbar CSF tap test (RTT), lumbar external CSF drainage (LED) and radioisotope cisternography (RIC) in predicting the outcome of shunt surgery, as well as the diagnostic and prognostic value of periventricular hyperintensity (PVH) and of the classic clinical triad in normal pressure hydrocephalus. Two hundred and seventy patients were referred to the Departments of Neurosurgery, in Nancy, France and in Istanbul, Turkey. The decision to perform surgery was based on the clinical presentation (all patients had at least two symptoms of the classic clinical triad), neuroimaging examinations and the results of the RTT (taps were performed on three consecutive days and at each tap a minimum of 30 to 40 cc of CSF was removed), the LED (drainage was performed for 3 days and the volume of CSF drained daily was a minimum of 150 to 250 cc) or the RIC...

A 68-year-old man developed progressive four-limb weakness and areflexia 17 days after an influenza vaccination. He was diagnosed with Guillain-Barre syndrome (GBS), and remained ventilator dependent and bed-bound for 3 months, despite plasmapheresis and immunoglobulin infusion. However, cognitive impairment, excessive daytime sleepiness, and motor disability were still present, even when he was no longer ventilator dependent. Brain computerized tomography scan and isotope cisternography was consistent with normal pressure hydrocephalus...

UNLABELLED: Radionuclide cisternography is an indispensable examination to detect cerebrospinal fluid (CSF) leakage in patients suspected of having spontaneous intracranial hypotension (SIH). However, it sometimes fails to demonstrate the site of CSF leakage, and in such cases, early bladder visualization is utilized for the diagnosis of SIH as an indirect finding. The aim of this work is to improve the diagnostic ability of radionuclide cisternography and to reevaluate the reliability of early bladder visualization as an indirect finding of CSF leakage...

An 81-year-old man with a history of ventriculoperitoneal (V-P) shunt placement for symptomatic normal pressure hydrocephalus presented with recurrence of confusion and gait disturbance. Radionuclide cisternography demonstrated loculation of In-111 DTPA in the abdominal wall. A soft tissue mass palpated at the location of tracer accumulation was confirmed to be extraperitoneal pooling of fluid at the site of coiling of the distal shunt tip. After surgical revision, with repositioning of the distal tube in the peritoneal cavity, the patient's symptoms promptly improved...

The most common problem addressed by dynamic radionuclide imaging of cerebrospinal fluid (CSF) abnormalities is differentiating patients with normal-pressure hydrocephalus (NPH) from those with other forms of degenerative brain disorder who would clearly not benefit from surgical treatment by ventricular shunting. Radionuclide cisternography (RC) SPECT and regional cerebral blood flow (rCBF) SPECT are critically important for the diagnosis and therapy management of patients with chronic hydrocephalus. However, radionuclide imaging is helpful not only in identifying patients with NPH showing improvement after shunting...

BACKGROUND: There is no agreement on the best diagnostic criteria for selecting patients with normal pressure hydrocephalus (NPH) for CSF shunting. The primary objective of the present study was to provide a contemporary survey on diagnostic algorithms and therapeutic decision-making in clinical practice. The secondary objective was to estimate the incidence of NPH. METHOD: Standardized questionnaires with sections on the incidence of NPH and the frequency of shunting, evaluation of clinical symptoms, and signs, diagnostic studies, therapeutic decision-making and operative techniques, postoperative outcome and complications, and the profiles of different centers, were sent to 82 neurosurgical centers in Germany known to participate in the care of patients with NPH...

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...
