Comparative StudyMembranous obstruction of the inferior vena cava: comparison of findings at sonography, CT, and venography.
Membranous or segmental obstruction of the inferior vena cava is one of the common causes of chronic Budd-Chiari syndrome. In this study, the venographic findings are compared with the results of sonography and CT in order to ascertain their role in the management of these cases. ⋯ Sonography was superior to CT in delineating pathologic venous anatomy of the inferior vena cava and hepatic veins whereas CT was better in evaluating hepatic cirrhosis and tumor. We believe that these techniques are useful complements to venography in the diagnosis and management of these cases.

ReviewNeoplastic diseases affecting the central skull base: CT and MR imaging.
Modern imaging techniques play a vital role in the diagnostic evaluation and follow-up of patients with neoplastic disease affecting the skull base. Many of these lesions have a high rate of recurrence if surgical removal is not complete. ⋯ Although these lesions are not common in clinical radiologic practice, the radiologist must be prepared to offer a reasonable differential diagnosis and a full evaluation of the extent of disease. This review presents some of the more commonly encountered tumors that can affect the skull base and describes their radiologic features, with emphasis on CT and MR imaging.
