Five cases of parasitic and mycotic infection affecting the biliary tract are reported. Special attention is paid to the radiological presentation of chlonorchiasis, ascariasis, echinococcosis, and candidiasis of the biliary tract. Each entity is briefly described, and the differential diagnosis and specific radiological patterns are discussed. Biliary tract manipulation with a balloon catheter and endoprosthesis is presented as an option for management of the biliary obstruction in some cases.

The authors report a case of Budd-Chiari syndrome caused by occlusion of all of the hepatic veins which was treated by percutaneous transluminal angioplasty. There were two recurrences requiring redilatation. Two years later, the patient was asymptomatic and off medication.

Fifteen cases of smooth muscle tumor of the alimentary tract were collected for analysis from several institutions. The findings showed that angiography is the best method available for diagnosis and evaluation of such tumors but is unable to differentiate benign from malignant lesions unless arterial invasion is detected. Computer tomography, ultrasound, and angiography are compared in the diagnosis of one case. Additionally, the angiographic pattern of a leiomyoblastoma is presented, presumably for the first time.

The angiographic findings 9 surgically proved cases of primary cystic neoplasms of the pancreas are reported. Angiography demonstrates the extent and origin of the tumour and permits in many cases a differentiation between benign and malignant lesions.

The double-contrast method, mucosal-relief study and compression technique associated with pharmacological hypotonia were retrospectively compared for accuracy in diagnosing 13 proved cases of shallow gastric ulcers. The double-contrast method was significantly more accurate than the other two.

The double-contrast method and the compressive technique associated with pharmacological hypotonia of the stomach were compared in 13 cases and found to be equally valuable in the diagnosis of erosive gastritis.
