Magnification renal scintigraphy in the differential diagnosis of septa of Bertin.

Eight consecutive patients, referred because intravenous urography (IVP) raised the question of hypertrophied septum of Bertin versus a pathologic mass, were examined using 99mTc labeled radiopharmaceuticals with magnification renal scintigraphy. The areas of concern showed a spectrum of activity, from normal to markedly increased, as compared to surrounding tissue. The activity correlated with the size of the mass effect on IVP. Increased resolution provided by pinhole magnification was important in evaluating these patients. We feel that magnification renal scintigraphy is valuable in the evaluation of intrarenal masses.
