 "respuesta": "Based on the provided coronal PD fat-suppressed ankle MRI series only:\n\n## Abnormal findings\n\n| Structure/category | Location | Description | Confidence |\n|---|---|---|---|\n| **Joint fluid / synovium** | **Tibiotalar joint**, greatest along medial and lateral gutters/anterior recess | Small tibiotalar joint effusion. Mild capsular/gutter fluid signal; possible mild synovitis/scarring, particularly anterolaterally. | **High** for small effusion; **Medium** for synovitis/scarring |\n| **Soft tissues / impingement region** | **Anterolateral ankle gutter**, adjacent to distal fibula/lateral talar shoulder | Mild ill-defined hyperintense soft tissue/fluid signal in the anterolateral gutter. In the clinical context of prior sprain and arthroscopy, this may reflect postoperative/scar tissue or residual synovitis/anterolateral impingement-type change. | **Medium** |\n| **Lateral ligaments** | **Lateral collateral ligament complex**, especially ATFL/CFL region near distal fibula | Ligaments are not optimally assessed on this coronal series, but there is mild irregular/thickened low-signal tissue about the lateral gutter/distal fibula, suggesting chronic sprain-related scarring. No definite acute ligament disruption seen on these images. | **Medium–Low** |\n| **Tendons** | **Peroneal tendon sheath**, posterolateral ankle | Trace-to-mild fluid signal around the peroneal tendons, compatible with mild tenosynovitis. Tendon continuity is preserved on this series; no definite split tear visible. | **Medium–Low** |\n| **Joint fluid** | **Posterior subtalar joint / sinus tarsi region** | Small amount of fluid signal at the subtalar joint region; likely mild subtalar effusion or recess fluid. | **Medium** |\n\n## Bones and cartilage\n\n| Structure | Assessment | Confidence |\n|---|---|---|\n| **Distal tibia, fibula, talus, calcaneus** | No acute fracture, stress reaction, or convincing focal marrow edema identified on this series. | **High** |\n| **Talar dome / tibial plafond cartilage** | No definite osteochondral lesion or full-thickness cartilage defect is visible on the provided coronal PD-SPAIR images. Cartilage assessment is limited by slice thickness and single-plane review. | **Medium** |\n| **Tibiotalar alignment** | Preserved on these images. No gross mortise widening. | **High** |\n\n## Ligaments and tendons otherwise\n\n| Structure | Assessment | Confidence |\n|---|---|---|\n| **Deltoid ligament complex** | Grossly intact without clear acute edema or disruption on this series. | **Medium** |\n| **Syndesmotic region** | No obvious widening or acute syndesmotic edema seen on this coronal series. | **Medium** |\n| **Posteromedial tendons — posterior tibial, FDL, FHL** | Appear grossly intact without convincing tenosynovitis on these images. | **Medium** |\n| **Anterior extensor tendons** | Grossly intact. No definite tenosynovitis identified. | **Medium** |\n| **Achilles tendon / plantar fascia** | Not well assessed on the provided slices; no obvious abnormality where partially seen. | **Low–Medium** |\n\n### Overall impression from this series\n1. **Small tibiotalar effusion**, with mild anterolateral gutter fluid/soft-tissue signal suggesting **mild synovitis or postoperative/scar-related impingement change**.  \n2. **Chronic lateral ligament sprain/scarring suspected**, without definite acute tear on this coronal sequence.  \n3. **Mild peroneal tendon sheath fluid/tenosynovitis**, no definite tendon tear visible.  \n4. No visible acute osseous abnormality or definite osteochondral lesion on the provided images."
