Brainstem evaluation with CT cisternography.
Seventy-eight positive contrast computed tomography (CT) cisternograms were reviewed to assess the normal anatomy of the brainstem and its surrounding cisterns. Normal brainstem and cisternal anatomy was found to be constant and symmetrical. The review included six patients with brainstem gliomas and five patients with extraaxial masses. In these patients CT cisternography accurately identified...
متن کاملBilateral cerebellopontine angle air-CT cisternography.
Recently , new methods in the workup of cerebellopontine angle (CPA) tumors have been established . These include computed tomography (CT) in combination with intravenous injection of contrast material [1], enhancement of cerebrospinal fluid with metrizamide [2], and most recently air-CT cisternography [3 , 4]. We describe a simple technique for examining both cerebellopontine angles with one l...
متن کاملCT cisternography of dolichoectatic arterial compression of the optic chiasm.
Dolichoectasia of the distal internal carotid arteries and the proximal anterior cerebral arteries is a well recognized abnormality. The angiographic and computed tomographic (CT) findings have been described [1-8]. Arterial enlargement has been implicated in chiasmal and optic nerve syndromes [1, 3-9]. We report a symptomatic patient with chiasmal deformity and associated arterial dolichoectas...
متن کاملGas CT cisternography of an intracanalicular vascular malformation.
Gas CT cisternography has been shown to be an excellent technique for diagnosing intracanalicular acoustic neuromas [1, 2]. While other intracanalicular lesions, such as meningiomas, hemangiomas, cholesteatomas, gliomas, and hamartomas, are much less common, they do occur [3-6]. We describe the cisternographic findings in a patient with a purely intracanalicular vascular malformation and point ...
متن کاملArachnoiditis simulating acoustic neuroma on air-CT cisternography.
Routine thin-sect ion CT after contrast enhancement may fail to demonstrate smal l acoustic neuromas, usually those smaller than 10 mm [1, 2]. Metrizamide CT cisternography has demonstrated such small acoustic neuromas, but cannot demonstrate an intracanalicular tumor accurately [3]. Pantopaque c isternography can demonstrate an intracanalicular mass, but has a high percentage of inconclusive e...
