Two cases of pulmonary lymphatic opacification during lymphangiography in the presence of a normal thoracic duct are reported. The most likely route of filling of the pulmonary lymphatics in the lower lobes is by reversed flow from the thoracic duct through the inferior pulmonary ligament lymphatics. Retrograde flow from the bronchomediastinal trunk is unlikely.

A patient had an ascending colon carcinoma in a right inguinal hernia sac, the first such instance to be reported. A second patient had a left colon carcinoma in a left inguinal hernia sac. Both patients had gastrointestinal symptoms and anemia which warranted a barium enema.
Thirty-one cases of renal vein thrombosis (RVT) were reviewed retrospectively for clinical laboratory, and radiographic findings. An underlying renal disorder was present in 28 cases, absent in only 3. This supports other evidence that RVT is usually a complication of renal disease rather than a primary event, and that nephrotic syndrome may be due to renal disease rather than RVT. The findings also confirmed the large spectrum of urographic appearances in RVT, and were used as a basis for developing specific and liberal indications for renal venography.
Late complications at the repair site of coarctation of the aorta include aneurysms and persistent coarctation. Aneurysms are usually due to failure of the surgical anastomosis and can occur many years after repair. Continued aortic coarctation may be due to either repair failure or failure of the anastomotic site to grow with the patient. Three cases are presented and the literature reviewed.

Nonvisualization of a kidney in an elderly man was investigated by computed tomography (CT). Simple low lying ureteral obstruction was excluded, multiple pathologic abnormalities were identified and causes for the nonvisualization are postulated. This case report demonstrates the important effect CT scanning produced on the clinical management of the patient in question.
This has been a review of some of the movements of the cervical spine. Much data remain to be accumulated and certainly much work must be done to evaluate the effect of forces in various directions upon these movements. Perhaps an improved understanding of these movements in association with an understanding of the pathogenesis of disc degeneration will enable us to better understand the development of spondylosis. Most important this review uncovers the fallacy of laying the blame for the development of cervical spondylosis solely at the door of increased or decreased mobility at certain area. Physical stress and tissue degeneration must be playing a significant role.

A Gamut is defined as a complete list of anything. As utilized here, it indicates a complete list of the possible causes of a particular scintigram finding. The procedure for developing a Gamut is discussed, ant its use as a tool for instructing residents in nuclear medicine is described. Sample Gamuts are presented and the Gamut approach to scintigram differential diagnosis is described.

The authors report six congenital abnormalities of the inferior vena cava detected on computed tomography (CT). The CT findings of one of these, the left inferior vena cava, have not been previously reported. The embryology of the inferior vena cava and the possible congenital abnormalities that can occur are discussed. Congenital abnormalities of the inferior vena cava are rare but potentially important to the radiologist, the surgeon, and the patient. They are easily identified on CT and should be considered when interpreting any CT of the abdomen or chest.
