Case report: acute segmental radiation nephritis on bone scintigraphy.

A case of radiation nephritis was diagnosed by the effect of delayed excretion of 99Tcm MDP on the superomedial aspects of both kidneys, which had been included in a radiation port to the thoracolumbar spine 6 months previously. Knowledge of the past history of radiotherapy and the radiation port, together with the classic scintigraphic features enable the diagnosis of this rarely demonstrated condition to be made.
