On ultrasonography, which finding is most consistent with PSD?

• A. Uniform echogenic pattern with no swelling.
• B. Calcifications within bone.
• C. Fiber disruption and swelling; hypoechoic/heterogeneous areas.
• D. Normal fibers.

Answer: (C)

Ultrasound shows the structure of soft tissues and how they’re arranged. When a connective-tissue injury occurs, the fibers themselves are disrupted and the surrounding tissue swells from inflammation. This appears as fiber discontinuity with swelling and a hypoechoic (darker) or heterogeneous area on the image, reflecting disorganized tissue and edema. In contrast, a uniform echogenic pattern with no swelling would mean the tissue is intact, and calcifications within bone point to bone changes rather than soft-tissue injury. Normal fibers would look continuous and well-organized without edema. The presence of disrupted fibers with swelling and hypoechoic/heterogeneous areas is the pattern that aligns with this condition.
