Skeletal scintigraphy in carcinoma of the kidney
British Journal of Urology
|April 1, 1983
Abstract:
The scintigrams and radiographs of 32 patients with renal carcinoma were reviewed. False negative skeletal scintigrams were observed in four of 12 symptomatic patients with proven skeletal metastases from carcinoma of the kidney. A negative scintigram therefore does not exclude the possibility of skeletal metastases in this condition.
Insights
Skeletal scintigraphy may miss bone metastases in kidney cancer patients. Even with symptoms, a negative scan does not rule out metastatic disease, requiring further investigation for accurate diagnosis.
Area of Science:
- Oncology
- Radiology
- Nuclear Medicine
Background:
- Renal carcinoma (kidney cancer) can metastasize to the skeleton.
- Skeletal scintigraphy is a common imaging technique used to detect bone metastases.
Purpose of the Study:
- To evaluate the accuracy of skeletal scintigraphy in detecting skeletal metastases in patients with renal carcinoma.
Main Methods:
- Review of scintigrams and radiographs from 32 patients diagnosed with renal carcinoma.
- Analysis of false negative findings in symptomatic patients with confirmed skeletal metastases.
Main Results:
- Four out of 12 symptomatic patients with confirmed skeletal metastases from renal carcinoma had false negative scintigrams.
- Skeletal scintigraphy demonstrated a significant rate of false negatives in this patient cohort.
Conclusions:
- A negative skeletal scintigram does not exclude the presence of skeletal metastases in patients with renal carcinoma.
- Clinical suspicion and further diagnostic imaging may be necessary when scintigraphy is negative but metastases are suspected.
