Summary
Residual Lipiodol ultra fluid (LUF) after galactography can mimic microcalcifications on mammograms. Recognizing specific LUF patterns aids in accurate diagnosis, preventing misinterpretation of breast imaging findings.
Area of Science:
- Radiology
- Medical Imaging
Background:
- Lipiodol ultra fluid (LUF) is a contrast agent used in galactography.
- Residual LUF after galactography can present diagnostic challenges on mammography.
- LUF may persist in breast ducts or cysts for extended periods.
Purpose of the Study:
- To describe mammographic appearances of residual Lipiodol ultra fluid (LUF) after galactography.
- To define specific patterns of LUF that may mimic microcalcifications.
- To aid in the accurate diagnosis of LUF residues.
Main Methods:
- Retrospective analysis of mammograms from 14 patients (aged 32-63) with LUF residues.
- Review of patient history including previous galactography procedures.
- Surgical correlation in cases with diagnostic uncertainty.
Main Results:
- In 12 of 14 cases, LUF diagnosis was straightforward due to typical mammographic patterns and available galactography records.
- In 2 cases, progressive LUF resorption mimicked intraductal calcifications, posing diagnostic difficulties.
- Three patients underwent surgery, revealing benign duct ectasia with foreign body inflammatory reaction.
Conclusions:
- Specific mammographic signs can help diagnose residual Lipiodol ultra fluid.
- LUF residues, though uncommon, can mimic benign and potentially malignant findings.
- Awareness of LUF imaging characteristics is crucial for radiologists to avoid misdiagnosis.
