BONE SCAN
HISTORY
Acute localised pain lower third fibula
TECHNIQUE
Three phase 99m Tc - HDP bone scan of both ankles and feet including
delayed images of both knees. Correlation is made with prior MRI right
ankle of 17/11/2008. 15/09/2008 - Broestrom Repair and medial ligament
repair.
REPORT
The early images show moderate increased vascularity in the right
ankle medially and laterally, especially medially.In the delayed
images, there is moderate to intense uptake adjacent right ankle,
especially in the right medial malleolus and distal tibia anteriorly.
There is mild to moderate uptake in the right subtalar joint.
There is mild periarticular uptake in the small joints of both feet
including the first MTP joint in keeping with mild degenerative
change. No intense focal increased vascularity is identified in the
distal third of the right fibula.
OPINION
1. Moderate to intense bone reaction adjacent right ankle, especially
medial malleolus and distal tibia anteriorly with increased
vascularity. This is presumed to be due to recent post surgical change
and there is history of corticosteroid injection. On its own, this can
be seen with synovitis. More intensse bone reaction in right medial
malleolus is presumably related to medial ligament repair.
2. No intense bone reaction identified in distal third of either
fibula to account for patient's presentation.
