Kager's fat pad refers (also known as the pre-Achilles fat pad) refers to the fat within the Kager triangle, which normally appears darklucent (fat density) on radiographs and has relatively defined margins. Pathologies affecting the aforementioned (and other nearby) bordering structures structures results in oedema in the fat pad, which radiographically appears as loss of the normal margins and increased density in the triangle.
Pathologies Distorting its Normal Appearance:
- Oedema
- Hemorrhage
- Infection (soft tissue, osteomyelitis)
- Inflammation (Achilles bursitis, peritendinitis)
- Thickened Tendons (xanthomatosis, rheumatoid arthritis, gout, ankylosis spondylitis, reactive arthritis)
- Adjacent neoplasm (soft tissue, osseous)
In the setting of trauma, oedema in Kager's fat pad should lead to a careful search for bony or soft tissue injury (ie. Achilles Tendon injury), perhaps requiring additional views and/or cross-sectional imaging depending on the clinical suspicion.
