Figure 1A.

(A) Plain radiographs of the tibia and fibula showing a small "cloud" of periosteal reaction consistent with a tibial stress fracture at the posterior-medial border of the left tibia. The accompanying bone scan confirmed the diagnosis.

Figure 1B.

(B) The bone scan is of both tibias. Increased uptake is noted along the posterior-medial border of the left tibia in the diaphysis.
