Intracranial tuberculosis is often insidious, may be difficult to diagnose clinically, and is neurologically devastating if untreated. The advent of computerized tomography has permitted earlier detection of the structural abnormalities associated with intracranial tuberculosis than was possible with older techniques. Correct radiologic interpretation can… (More)
Two cases are presented in which the preoperative diagnosis of abdominal cerebrospinal fluid pseudocyst was made by computed tomography (CT). The collection can be well outlined by this method, and measurement of density values characterizes the contents as a water density; the relationship of portions of the shunt catheter to the pseudocyst can be… (More)
Computed tomographic scans were performed in 34 patients following lumbar introduction of metrizamide. Imaging of the cranial spaces was obtained with horizontal and inclined (25 degrees) as well as coronal planes. Mass lesions within and encroaching upon the cisternal spaces were demonstrated, and the ventricular system was shown with varying degrees of… (More)
Cisternography with metrizamide (Amipaque) and hypocycloidal tomography was found to depict cisternal anatomy with detail and precision not obtainable with any other technique. Clinical tolerance is comparable to that of encephalography if suitable precautions are followed. All side effects observed had disappeared 36 hours after injection, and no delayed… (More)
Eight pathologically proven cases of pineal region tumors examined by computed tomography (CT) were found upon reviewing 11,000 consecutive CT studies at the Massachusetts General Hospital. The CT scan findings of the eight cases are described and related to a pathological classification of pineal tumors.
The function of ventriculoperitoneal shunts was evaluated by ultrasonography in 17 patients. In 10 of 15 patients with properly functioning shunts, a small amount of free intraperitoneal fluid was found. However, absence of demonstrable fluid did not reliably indicate shunt malfunction. No asymptomatic patients had large amounts of ascites or loculated… (More)
A method employing an 8-F Fogarty balloon catheter to provide temporary occlusion of a pseudoaneurysm of the ascending aorta prior to surgery is presented. The technique of occlusion and its benefits are discussed.
Enhancement of CT attenuation values of the CSF cisterns by the lumbar injection of metrizamide has been shown to be of value in demonstrating the anatomy of the cisterns. Tumors involving the cisterns, such as acoustic neurinomas and pituitary adenomas, are clearly defined. Coronal scanning was superior to horizontal views in many cases.
