A simple method of shielding the hand during cross-compression angiography is described. A standard lead glove with the fingertips cut out of the palmar aspect is used, allowing sensation and mobility while still protecting the hand.
Obstruction and reflux occur fairly commonly in the duplex kidney. Although obstruction with attendant hydronephrosis is more frequently seen in the upper pole of a duplex system, a similar process involving the lower pole should be considered in the differential diagnosis of renal mass lesions. Four cases are described in which lower pole hydronephrosis simulated neoplasm.
An unusual case of granulocytic sarcoma (chloroma) of the parenchyma of the brain occurring in a patient with acute myelocytic leukemia in remission is described and the literature reviewed. The patient presented with an intracranial mass without clinical evidence of meningeal involvement. The value of 99mTc scan in CNS leukemia is shown.
Two cases of chronic aortic dissection are presented. In both, plain chest roentgenograms revealed calcification in the outermost aspect of the dilated aorta. It is clear that this represented calcification of the dissection rather than of the true intima. These cases indicate that apparent aortic intimal calcification with dilatation of the aorta is not completely diagnostic of an arteriosclerotic aneurysm and that a chronic calcified aortic dissection must also be considered in the differential diagnosis.
A 500-W fiber optics cold light used to transilluminate the angular and frontal veins allowed quick, accurate delineation of the veins for percutaneous orbital venography. It also allowed the surgeon to avoid cutting the angular vein when operating on the lacrimal sac.
