The results of phleborheography were normal, but on the basis of an abnormal phlebogram and an initially normal computed tomographic scan of the legs, the patient was given anticoagulants. Over a one-month period, local symptoms in the calf failed to resolve. On reassessment of the initial roentgenograms, a soft-tissue neoplasm was found and confirmed by angiography and biopsy.
