Three-dimensional helical CT angiography of skull base meningiomas.
PURPOSE To describe the findings of skull base meningiomas on three-dimensional CT angiograms obtained with helical scanning and to evaluate the usefulness of this method. METHODS Fifteen patients who had a meningioma near the skull base were examined with helical CT after receiving an intravenous bolus injection of contrast material. RESULTS All meningiomas had either a honeycomb (12 patie...
متن کاملThree-dimensional alloplastic orbital reconstruction in skull base surgery.
INTRODUCTION The orbit may be directly involved by neoplasms or other destructive processes arising from the orbital contents, the osseous framework or, indirectly, as extensions of extraorbital tumors from the sinuses or cranial vault. In most osseous neoplasms of the orbit, and in tumors with extension into the orbit from surrounding areas, resection of part or all of the orbital walls will b...
متن کاملDissectable modified three-dimensional temporal bone and whole skull base models for training in skull base approaches.
Training in dissection of the skull base is essential for anatomical understanding and correct surgical techniques, but chances for cadaver dissection are limited, so a substitute is very desirable. Modifications of commercially available three-dimensional (3D) temporal bone and whole skull base models made from surgically dissectable artificial bone are proposed to include artificial dura mate...
متن کاملDiagnostic accuracy of three-dimensional CT reconstruction and cephalometry for lateral skull base tumors.
OBJECTIVE To explore the diagnostic accuracy of three-dimensional CT reconstruction and cephalometry in lateral skull base tumors. PATIENTS AND METHODS Fifty-eight patients with lateral skull base tumors were randomly divided into control group (n = 29, examined with conventional diagnostic technique) or study group (n = 29, examined with three-dimensional CT reconstruction and cephalometry)....
متن کاملPrenatal Sonography in Hydranencephaly
ydranencephaly is a severe, sporadic brain abnormality characterized by absence of the cerebral hemispheres, which are replaced by a large supratentorial fluid-filled saclike structure surrounding the brain stem.1,2 This condition is thought to be the result of extensive brain necrosis secondary to a vascular insult involving the internal carotid arteries, which occurs after the brain and ventr...
