Six cases of spontaneous dissecting aneurysm of the internal carotid and vertebral arteries are reported. The angiographic findings and the clinical aspects of the disease are described. The lesion is not as rare as generally assumed.
A case of traumatic exophthalmos due to an arteriovenous fistula between the middle meningeal artery and the veins at the base of the skull is reported. There was no involvement of the cavernous sinus. Embolization following selective transfemoral catheterization of the external carotid artery resulted in complete relief of the symptoms.
In 102 patients, cervical metrizamide myelography was performed using a lateral C1/C2 approach. The procedure is of low risk, is easily performed and provides excellent diagnostic result. The authors hold this method--a few cases excepted--to be best for the investigation of the cervical region.
Cerebral angiography still remains the method of choice for the evaluation of cerebral vascular malformations--even in this day and age of CT. In rare cases, however, these conditions can be missed by angiography, whereas CT can provide important though not pathognomonic clues, with a definite diagnosis possible only by surgical exploration.
Fifty extra-intracranial arterial anastomoses were performed in 48 patients. The importance of a precise angiographic study in the pre- and post-operative period is emphasized. The different angiographic patterns of the anastomosis, its variation in time, the possible cause of failure, and the role played by the EIAB on the cerebral blood flow are described and discussed. The problems of extension and time of the postoperative angiographic examination, are also discussed.
Case presentation of a four year old child with aggressive aneurysmal bone cyst of the fourth lumbar vertebra. Microscopic examination demonstrates a benign lesion. The roentgenographic pattern reflects a tumorlike bone destruction with signs of malignancy. Clinically, progression and invasion, similar to a semimalignant tumor, is noticed. The possible nature of this aggressive behaviour is discussed.
Congenital choledochal cysts are classified into three types (type A = cystic dilatation, type B = diverticula, Type C = choledochocele). In addition, all cases of types A and B may have anomalies of the pancreaticobiliary duct system. In type I the pancreatic duct enters the common duct and in type II the common duct enters the pancreatic duct. These anomalies are considered etiological factors in the development of choledochal cysts and are important for prognosis and therapy. Types A and B should be mainly treated by choledochocystojejunostomy (Roux-en-Y), while in type C an endoscopic transpapillary splitting is recommended.
