Summary
Elastofibroma dorsi, a rare soft-tissue tumor, presents as a lenticular mass. Imaging characteristics on computed tomography (CT) and magnetic resonance imaging (MRI) can accurately predict its histological features, aiding preoperative diagnosis.
Area of Science:
- Radiology
- Pathology
- Oncology
Background:
- Elastofibroma dorsi is an extremely rare soft-tissue tumor.
- Comparative studies on imaging and pathology are scarce, especially in China.
Purpose of the Study:
- To investigate the clinical, imaging (CT and MRI), and pathologic features of elastofibroma dorsi.
- To enhance preoperative diagnosis of this rare condition.
Main Methods:
- Retrospective analysis of 6 elastofibroma dorsi cases.
- Review of related literature.
- All patients underwent MRI; 4 had CT scans.
Main Results:
- Tumors appeared as lenticular masses in the subscapular region in patients over 30.
- CT density and MRI signal intensity mimicked muscle with fat-like areas.
- Fat-suppression MRI sequences revealed features corresponding to dense collagen and mature adipose tissue.
Conclusions:
- CT and MRI findings correlate with histological features of elastofibroma dorsi.
- Characteristic imaging findings facilitate accurate preoperative diagnosis.
