title: Calf hematoma mimicking thrombophlebitis: sonographic and computed tomographic appearance.
abstract: Five patients with calf hematomas presented with signs and symptoms suggesting thrombophlebitis, obscuring the correct diagnosis. Venography showed no venous thrombosis; further diagnostic studies using ultrasound and/or computed tomography provided the correct diagnosis in all patients. Ultrasound showed a hypoechoic mass clearly demarcated from surrounding soft tissue, while computed tomography showed a well-defined mass whose density depended on the age of the hematoma.
