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 ...

Dementia and hydrocephalus in an elderly female were related to basilar impression caused by Paget's disease of the skull. Ventricular and lumbar thecal pressures were normal, but isotope cisternography suggested obstructive hydrocephalus. The patient improved after ventricular shunting. The importance of prompt investigation of dementia occurring in patients with Paget's disease is emphasised.

introduction artificial and natural radionuclides are found in diverse environmental compartments, such as water, soil, rocks, vegetables, animals, and human body tissues. as such, humans and environments are at constant exposure of these radiation types. in this research investigated specific activities of radionuclide and dose assessment of some species of mushrooms. materials and methods in ...

statement of problem: condylar hyperplasia of the mandible is a self limiting abnormality which can cause facial asymmetry, temporomandibular joint (tmj) dysfunction and esthetic problems. treatment planning is based on the results of isotope scanning, clinical findings and patient age. single photon emission tomography (spect) is considered to be a sensitive method in the calculation of condyl...

The diagnosis of leptomeningeal cysts by isotope cisternography is described in four cases. The cysts are visualized as abnormal local collections of the radiopharmaceutical, best demonstrated 48 hours after lumbar injection. The investigation makes it possible to diagnose the cyst at an early stage, before severe clinical symptoms and changes in the bones of the skull develop. Cases of leptome...

The unique symptom of intracranial hypotension (IH) is an orthostatic headache caused by low cerebrospinal fluid (CSF) pressure and is not so rare. IH results from loss of CSF caused by a dural defect in the spine, cranial vault, or skull base. The classic orthostatic headache commences within 15 minutes, but occasionally symptoms last up to several hours, after standing or upright sitting posi...
