CAPD fluid: A common cause of photon deficient lesions on 99mTc-D.T.P.A. scans in renal transplant patients

Single or multiple transient photon deficient areas on 99mTc-DTPA scintigrams were found in 40% of a series of 34 patients who had undergone renal transplantion directly from CAPD maintenance. Ultrasound showed only loculated intraperitoneal CAPD fluid adjacent to the transplant with no evidence of local complications. We conclude that such collections are a common cause of photon deficient areas on 99mTc-DTPA transplantscintigrams and the absence of ultrasound, these appearances should be interpreted with caution.
