Matsuura Department of Radiology Kyushu University Hospital Fukuoka Japan Summary Forty-two acoustic neurinomas and seven meningiomas in the cerebellopontine angle were reviewed, and the radiological differential diagnosis of these tumors is discussed. Though enlarged internal auditory meati and characteristic CT findings were reasonably reliable indicators for the diagnosis of acoustic neurinomas, it was angiography which substantiated their correct diagnosis. An arcuate vein was frequently demonstrated with acoustic neurinomas, but never with meningiomas. Visualization of tangled veins seems to favor a diagnosis of acoustic neurinomas. Contrary to earlier reports, tumor stains were most frequently visualized using selective external carotid arteriography. The degree of tumor stains did not aid in differentiating acoustic neurinomas from meningiomas. The importance of using angiotomography, especially in the anteroposterior projection, and external carotid angiography during prolonged injections of large amounts of contrast media, is emphasized.

Norton Department of Diagnostic Radiology University of Kansas Medical Center Kansas City Kansas USA Department of Radiology University Hospital of Jacksonville 655 West Eighth Street 32209 Jacksonville FL USA Summary A meningioma demonstrating unusual anatomical and clinical manifestations is described. This intracranial tumor originated in the petrous region and extended into the neck, the patient remaining neurologically asymptomatic for nearly 2 years. The radiological features of this tumor as well as a review of the pertinent literature are presented.

Chrzanowski Department of Radiology Kantonsspital Aarau Switzerland Department of Pathology Kantonsspital Aarau Switzerland Bürgerspital CH-6300 Zug Switzerland Summary A case of a cholesterol-containing granuloma of the orbit studied by bone scanning and selective carotid angiography is presented. Bone scanning with 99m Disphosphonate disclosed a solitary focus of intense activity in the right orbitofrontal region. On the selective angiogram of the right external carotid artery a faint vascular blush was found in the orbital wall.

Hosea Department of Radiology St. Geertruiden Hospital Deventer The Netherlands Department of Neurology St. Geertruiden Hospital Deventer The Netherlands Summary During the last few years transfemoral epidural venography has increasingly been used for diagnosing lumbar disc herniation. Occasionally this method may reveal an unexpected malignant tumour with the clinical symptoms of lumbar disc disease. Therefore it is of interest to be acquainted with the venographic signs of malignancy in this area. Moreover transfemoral epidural venography can be of help in the delineation of a tumour in the vertebral canal. If the double-catheter method is used, the anterior epidural venous plexus will, as a rule, be adequately shown up to the level of T 10 . Occasionally higher thoracic levels also are visualised. The procedure can easily be performed on an out-patient basis and is well tolerated by the patient. The complication rate is very low. The use of ioxaglate (Hexabrix) minimizes the post-injection reactions to the contrast medium.

Yoshida Department of Radiology Niigata University Niigata Japan Department of Neurosurgery Niigata University Niigata Japan Department of Neuropathology Niigata University Niigata Japan Summary Two cases of the anterior inferior cerebellar arteries originating from the cavernous and precavernous segments of the internal carotid artery are reported. In one case the course of the anomalous artery was confirmed by autopsy. This anomalous artery is considered to be a variant of persistent primitive trigeminal artery. The clinical significance is discussed briefly.
