Clinical Details: Ongoing pain 3 months post-surgery. ? cause
Technique: Sagittal T1 sequence with STIR sequence, axial proton density and STIR sequence.
Oblique coronal proton density sequence.
Findings:
Metallic artefact is noted associated with the medial malleolus as well as the lateral malleolus.
The adjacent deltoid ligament appears slightly thickened and increased in signal. It appears to be intact.
Hyaline cartilage of the talar dome appears normal.
The anterior talofibular ligament is thickened and ill-defined. The calcaneofibular ligament is also thickened. The posterior talofibular ligament appears intact. The syndesmosis appears intact.
The tendons of the ankle appear intact including the peroneal tendons and both the medial anterior tendons. No significant joint effusion is seen. The subtalar joint appears normal. The sinus tarsi appears normal.
There is a separate bone fragment associated with the tip of the lateral malleolus visible on the sagittal PD sequence.
Impression:
Post-surgical ankle. There is thickening and increased signal involving what appears to be intact deltoid ligament. No other significant abnormality demonstrated.
