Ureteral obstruction by an extrinsic object is rare. We herein report a case of renal colic caused by a shotgun pellet lodged in the ureter seven years after the injury. Computerized tomography scan and antegrade pyelogram demonstration were obtained.
In a series of 225 patients with lymphoma studied by computed tomography, involvement of the kidney(s) was found in 11 (4.9%). These cases were then also studied by ultrasound. Because of the characteristic findings of computed tomography and sonography in renal lymphoma, a reliable diagnosis was possible along with an accurate assessment of the incidence and types of renal involvement. Illustration of this material along with a discussion of the clinical implications of these findings is presented.

Atypical measles pneumonia should be considered an explanation for nodular pulmonary lesions in older children and young adults. The disorder can develop in children immunized with inactivated measles virus vaccine who are then exposed to natural measles virus. Individuals given the vaccine when it was used (1961--1968) are now at risk to develop atypical measles pneumonia. This pneumonia may have a lobar or diffuse bronchopneumonia pattern. Three cases of this disorder are described. In one case, radiography showed calcification in the nodules 6 years after the pneumonia. Complicated and possibly hazardous workups can be avoided by awareness of this disease.
In a female patient who presented with the complaint of dysuria, angiography was required to distinguish a vascular impression on the renal pelvis from a possible tumor or calculus. Neither intravenous urography nor retrograde pyelogram clarified the smooth filling defect sufficiently to rule out the possibility of a urothelial tumor.
Of all aortic dissections, 10% are chronic. Typically they arise distal to the left subclavian artery and have reentry points into the true lumen. Pain may be minimal or absent and patients often present with cardiac failure. Chronic dissections are more likely to appear radiographically as atherosclerotic aneurysms on a chest film than are acute dissections. Four cases of chronic dissections found incidentally during angiography are presented.

Only 13 cases of adrenal hemangiomas have been reported, none studied angiographically. Two additional cases, evaluated preoperatively, are presented. The radiographic finding of phleboliths, when present, with the characteristic angiographic appearance of hemangiomas, allows the radiologist to correctly diagnose this benign tumor preoperatively, and where surgical risk is high, prevent a serious operative procedure.

Transient visualization of superficial collateral abdominal veins can occur in intravenous urography in some patients with the superior vena cava syndrome. The findings are characteristic enough to lead the radiologist to the correct diagnosis. A presentation and explanation of this finding is made.
