Anterior Thigh Pain or Tenderness: A Diagnostically Useful Manifestation of Bacteremia

• In four patients with putative infectious process, anterior, bilateral proximal thigh pain and tenderness unaccompanied by generalized myalgias developed. This unusual manifestation, observed in these and other patients, was associated with demonstrable bacteremia. Aside from tenderness, no local abnormalities were found and the pain and tenderness disappeared after appropriate therapy. Creatine kinase levels, measured in three of the four patients, were elevated in only one. This manifestation is useful clinically as it strongly suggests bacteremia; attention to this finding can be lifesaving. ( Arch Intern Med 1985;145:657-658)
