title: [The diagnosis of intracranial A.V. malformation with orbital involvement by B-scan, colour Doppler and CT scan].
abstract: 20 patients with intracranial A.V. malformation with orbital involvement were examined by B-Scan (Real- time ophthascanB). colour doppler (Acason 128) and CT scan. These patients were confirmed in clinically and other examination. Ultrasonography Showed dilated superior ophthalmic vein and its pulsating which are Synchroniged with the heart beating; the echo-free cavity changed in shape upon compression with the probe and some thickened extraocular muscles. The flowing counter pulsating and volume of blood stream were showed clearly in colour doppler. CT scan showed dilated superior ophthalmic vein, thickened extraocular muscles and dilate shadow of cavernous sinus. If strengthen scan to be done, the malformation of cerebrum artery and vein can be showed clearly. These examination are of value in diagnosis. The rate of ultrasound and CT scan for the differential-diagnosis was discussed.
