Loop catheter technique: a simple, rapid method for left adrenal vein catheterization.
A simple method for left adrenal vein catheterization using the loop catheter technique is described. Thirty-three patients undergoing evaluation of their hypertension were studied. In all patients, selective catheter placement required 3--5 min. Adrenal venography was performed in 14 patients.

Calcific tendinitis of the flexor carpi ulnaris presents a characteristic radiographic appearance of amorphous calcification near the pisiform. This calcification frequently is associated with acute symptoms and may be related to certain occupations and hobbies. Knowledge of the pertinent anatomic and radiographic criteria permits accurate diagnosis.

CT evaluation of anomalies of the inferior vena cava and left renal vein.
Two patients with duplication of the inferior vena cava and two patients with a retroaortic left renal vein were examined by computed tomography (CT). The characteristic CT appearance of these two entities, as well as circumaortic left renal vein and transposition of the inferior vena cava, is discussed. A scheme by which these anomalies of the inferior vena cava and left renal vein may be distinguished from one another and from pathologic entities such as lymphadenopathy and a dilated gonadal vein is reported.

Pneumocystis carinii infection of the lung: radiologic and pathologic correlation.
The incidence of Pneumocystis carinii infection of the lung was determined in 100 consecutive autopsies on patients with hematologic malignancies and in a control group of 50 patients with acute myocardial infarction and chronic obstructive pulmonary disease. Thirteen instances of infection were found in the study group and one instance in the control group. Of the 14 patients with P. carinii infection, five were classified as uncomplicated P. carinii pneumonia with typical host response and five had no evidence of any host response to the presence of the organisms. ⋯ The five patients with the typical histologic response to the presence of P. carinii organisms all showed diffuse pulmonary densities on the chest radiographs in accordance with the classic descriptions of P. carinii pneumonia. The five without any evidence of host response to the presence of P. carinii organisms showed no evidence of parenchymal disease on chest radiographs. The finding of P. carinii organisms in the lung is not necessarily an indication of clinically significant disease and, from this study, it seems that chest radiography is of considerable importance in determining the significance of such infestation.
