Vascular compression of the superior infundibulum causing calyceal obstruction. Scintigraphic findings.
Radionuclide imaging in obstructive uropathy has concentrated on disorders of the pelviureteric junction and lower urinary tract. There is a paucity of information, however, available on the scintigraphic manifestations of disorders of the calyces and infundibulum. These conditions may be responsible for similar symptoms, and thus recognition of abnormal retention of activity within one or more calyces offers important diagnostic information. One of these disorders is vascular obstruction of the superior infundibulum, and this report describes the radionuclide appearance of this surgically curable condition.
