Findings—particularly cartilage and ligament abnormalities—would require confirmation on the remaining MRI sequences.\n\n### Abnormal or suspicious findings\n\n| Location | Description | Confidence |\n|---|---|---|\n| **Anterior calcaneus, near the anterior process** | Focal patchy increased marrow signal on the early slices, suspicious for localized marrow edema. No definite fracture line or displaced fragment is visible. | **Medium** |\n| **Calcaneonavicular region** | The anterior calcaneal process and adjacent navicular appear closely approximated, with a poorly defined intervening interface. A nonosseous coalition is a consideration, but is **not established** on these images. | **Low** |\n| **Medial and plantar intrinsic foot musculature; partially included distal calf** | Prominent, heterogeneous fluid-sensitive hyperintensity involving several muscle compartments, suspicious for muscular edema. The cause cannot be determined here; denervation should not be diagnosed from this series alone. Some contribution from nonuniform fat suppression is possible. | **Medium** |\n| **Ankle/hindfoot joint recesses** | Small amounts of fluid in the tibiotalar and subtalar recesses; no large effusion. | **Medium** |\n| **Perimalleolar superficial soft tissues** | Mild patchy edema-like signal, most apparent laterally. No discrete superficial collection is identified. | **Medium** |\n\n### Other structures\n- **Bones:** No definite displaced fracture, collapse, or destructive osseous lesion.\n- **Cartilage:** No convincing focal talar-dome osteochondral defect. Cartilage thickness and the degree of joint-space narrowing cannot be reliably assessed at this resolution.\n- **Ligaments:** The lateral ligament complex, syndesmotic ligaments, and deltoid components are not sufficiently delineated to confidently grade injury. No definite ligament rupture can be established.\n- **Tendons:** No convincing tendon discontinuity or retraction. The visualized Achilles tendon appears continuous. Medial flexor tendon sheaths are difficult to distinguish from the adjacent high-signal soft tissues; definite tenosynovitis or a split tear cannot be confirmed.\n\n**Most important to verify on the complete examination:** anterior calcaneal marrow signal and the calcaneonavicular interface, along with the apparent extensive muscular signal abnormality."
