Summary
Bilateral adrenal metastases from cancers like breast and lung are often silent. A new "head light" sign on sonograms can accurately diagnose these adrenal gland metastases.
Area of Science:
- Oncology
- Radiology
- Medical Imaging
Background:
- Adrenal gland metastases are frequently asymptomatic.
- High incidence in breast, lung carcinoma, and melanoma patients.
- Diagnosis of bilateral adrenal metastases can be challenging.
Purpose of the Study:
- To introduce and validate the "head light" sign.
- To improve diagnostic accuracy for bilateral adrenal metastases.
Main Methods:
- Retrospective review of sonograms from over 50 patients.
- Analysis of adrenal masses for metastatic lesions.
- Identification of the "head light" sign.
Main Results:
- 10 out of 50+ patients had bilateral adrenal metastases.
- The "head light" sign was observed in these cases.
- Demonstrated accuracy of the "head light" sign.
Conclusions:
- The "head light" sign is an accurate sonographic finding.
- Facilitates diagnosis of bilateral adrenal metastases.
- Useful in patients with high-risk primary cancers.
