Incidental Detection of Adult Polycystic Kidney Disease on Routine Bone Scan

“…Several reports in the literature have correlated the renal images seen on bone scans with roentgenographic findings (2,5,8,9,11,12,14). Among the readily detectable renal abnormalities are small, absent, or displaced kidneys, focal renal parenchymal lesions (focal area(s) of increased or decreased radionuclide activity), asymmetric renal activity, and bilateral urinary tract obstruction.…”

“…The importance of evaluating the kidneys on routine bone scans for structural abnormalities has been emphasized in the literature (1, 2,5,8,9,11,12,14). As the kidneys have a high extraction efficiency for " m Tc-labeled bone scanning agents, abnormalities are well visualized on routine skeletal scintigraphy (7, 10).…”

“…The incidental detection of renal abnormalities on a routine bone scan has been previously reported (1-3, 5,8,9,[11][12][13][14]. There is, however, only one report in the literature, to our knowledge, of adult polycystic kidney disease so diagnosed (8).…”

Demonstration of Renal Mass Lesions by Early Dynamic Imaging during Bone Scintigraphy

“…A renal carcinoma may be revealed as a focal parenchymal defect (2,7,8,10) but if the lesion is quite small or peripherally located it may not be seen at all (2). Few cases of increased radionuclide uptake of the tumour, attributed to calcification, have been described (11)(12)(13).…”

The role of skeletal scanning in clinical oncology.

“…In some cases 24 hours may need to elapse before adequate pelvic images are obtained. Unsuspected abnormalities in the renal tract can be detected from the bone scan,38 39 including renal carcinoma, which usually gives rise to a filling cold defect on the renal image but may also show increased tracer uptake.40 Evaluation of the renal tract is especially important in patients with tumours which may cause urinary tract obstruction, such as carcinoma of the uterine cervix.41 The combination of the absence of the renal image and diffusely intense skeletal uptake of the tracer is usually due to metabolic bone disease, but may result occasionally from widespread metastases. 42 Indications for bone scanning in patients with cancer-There are six main indications for bone scanning in patients with malignant disease.…”
