The Ask-Upmark kidney. Roentgenographic and pathological features

E. Himmelfarb, J. G. Rabinowitz, L. Parvey, S. Gammill and B. Arant

The Ask-Upmark kidney represents an unusual manifestation of a segmental hypoplastic kidney in which the lesion may be local or diffuse, and may involve one or both kidneys. It is almost always associated with hypertension and is, therefore, potentially curable when localized to a single kidney. It is imperative to recognize this disease in order to distinguish it from other entities that cause hypertension.
