📌 Elastofibroma Dorsi
Elastofibroma dorsi is a benign soft-tissue tumor commonly found in the infrascapular or subscapular region. It is bilateral in up to 30% of cases and has a slight right-sided predilection when unilateral.
✅ Location
- Found deep to the serratus anterior and latissimus dorsi muscles.
- Poorly defined soft-tissue mass with no true capsule.
✅ CT Findings
- Poorly defined soft-tissue mass.
- Attenuation similar to adjacent skeletal muscle.
- Located in the infrascapular or subscapular region.
✅ MRI Findings
- Alternating fibrous and fatty components.
- No identifiable capsule but relatively well-defined margins.
- Fibrous component: Isointense to muscle.
- Fatty component: High signal intensity on T1WI and T2I
- Heterogeneous low-level enhancement.
✅ Key Imaging Features
- Heterogeneous signal mass deep to the serratus anterior and latissimus dorsi muscles.
- Streaky internal fat signal is a distinguishing feature.
- Signal intensity similar to skeletal muscle.
