Diverse bone scan abnormalitites in "shin splints".

Four young patients who presented with pain over the anterior compartment of the legs, gave a recent athletic history suggesting stress fractures. Although radiographs were initially normal in all four cases, the bone scintigrams were positive. The individual findings, however, were quite different. In one there was a single focal area of increased radioactivity in each of the tibias; the second patient had uneven uptake of radiotracer and several foci of accumulation in the fibulas; the third showed diffuse linear tibial uptake suggesting periosteal lesions; and the fourth case revealed uptake in the lateral malleolus and in bones of the foot.

Clinical correlation of hepatic flow studies.

In 100 consecutive hepatic flow studies, 84 were read as negative. Of these, 73 (87%) also had negative static images. Knowing the nature of the primary tumor did not definitively aid in predicting whether hepatic meastases would have detectable early flow. Five cases showed early flow without defects seen in the static images. Three of these were probably related to lymphomas or allied disorders with altered flow. Two cases were in individuals with gastric carcinoma who had abdoninal radiation. One extrahepatic tumor was detected in the series.
