Case Discussion

Delayed onset muscle soreness (DOMS) is muscle pain or soreness that occurs after acute muscle overuse (e.g. weight-lifting or aerobic exercise). The soreness typically begins within 2 to 3 hours of the activity and peaks at 2 to 3 days although this is variable. The MR findings of DOMS show areas of increased T2 and DP with fat saturation signal within the involved musculature, occasionally mimicking a low-grade muscle strain. Abnormal signal has been shown to persist for up to 3 weeks after resolution of symptoms.
