title: Infrabladder "cup defect" following prostatectomy: recognition on bone scintigram.
abstract: Seventeen bone scintigrams, made after prostatectomy for proven or suspected carcinoma, showed a "cup defect" below the bladder. This defect was likely related to the volume of tissue removed at the time of transurethral prostatectomy. In two cases, the defect was not present on images made before prostatectomy but was clearly seen after the operation. The time of persistence of the "cup defect" is discussed, as well as the differential diagnosis of the finding.
