Pulmonary venous varix is a well known radiographic entity. Case reports are presented to illustrate the following unusual aspects of this lesion. 1. Hypoplasia of a major pulmonary vein results in increased pulmonary blood flow through the remaining normal ipsilateral pulmonary vein. ⋯ This is most common in children. 3. Elevated pulmonary venous pressure causes dilatation of the central pulmonary veins. Sudden formation of a pulmonary venous varix in a patient with mitral valvular disease may be evidence of a sudden elevation of left atrial pressure.

Twenty pediatric patients with malignant disease were studied by whole body gallium scans. Seven had Hodgkin's disease, five had soft tissue sarcomas, three had neuroblastomas, two had Wilm's tumors, and one each had a hepatoblastoma, embryonal cell carcinoma, and sacrococcygeal teratoma. ⋯ The method served best in patients with Hodgkin's disease, where the true positive rate was 64%. In no instance did the gallium scan affect the clinical management of a patient.
