 "respuesta": "**Limited interpretation based on the provided sagittal PD fat-suppressed series only.**\n\n## Abnormal / possibly abnormal findings\n\n| Structure | Location | Description | Confidence |\n|---|---|---:|---|\n| **Joint fluid / synovium** | Tibiotalar joint | Small ankle joint effusion, visible in anterior and posterior recesses. | **High** |\n| **Joint fluid / synovium** | Posterior subtalar joint / sinus tarsi region | Small subtalar joint effusion with fluid/edema-like signal extending into the sinus tarsi/tarsal canal region. Could reflect mild synovitis or sinus tarsi inflammation. | **Medium** |\n| **Soft tissues** | Sinus tarsi / lateral hindfoot | Mild lobulated fluid-signal/edema in the sinus tarsi region; a small ganglion/synovial cyst component is possible. | **Medium** |\n| **Tendons** | Posterior ankle, likely flexor hallucis longus tendon sheath | Mild fluid tracking along the posterior ankle flexor tendon sheath, most consistent with mild FHL tenosynovitis. | **Medium** |\n| **Plantar fascia / heel soft tissues** | Proximal plantar fascia at calcaneal origin | Possible mild thickening/perifascial edema at the plantar fascial origin; no clear tear or retraction seen. | **Low–medium** |\n| **Soft tissues** | Subcutaneous tissues around hindfoot/ankle, greatest posterior/lateral and plantar heel | Mild nonspecific subcutaneous edema. | **Medium** |\n| **Bones** | Talus, small intraosseous focus | Tiny fluid-signal focus in the talus, favored small subchondral/intraosseous cyst or vascular channel; no surrounding marrow edema. | **Low** |\n\n## Structures without definite abnormality on these images\n\n- **Bones:** No acute fracture, stress fracture, or convincing bone contusion identified. No definite osteochondral lesion of the talar dome seen on this sagittal series.  \n- **Cartilage:** Tibiotalar and subtalar articular surfaces appear grossly preserved; no focal full-thickness cartilage defect evident.  \n- **Achilles tendon:** Appears intact without tear.  \n- **Other tendons:** No definite tendon rupture identified on these sagittal images.  \n- **Ligaments:** Lateral, medial/deltoid, and syndesmotic ligaments are not well assessed on this sagittal-only view; no definite complete ligament disruption is visible here."
