[Mycotic aneurysm of the posterior tibial artery and pseudo-phlebitis: contribution of color Doppler ultrasonography].

Mycotic aneurysm of the posterior tibial artery and pseudophlebitis: role of color Doppler sonography A case of a 78-year-old male patient presenting with endocarditis caused by Streptococcus bovis and pseudophlebitis of the left lower limb is described. Color Doppler sonography ruled out thrombophlebitis and showed a large pulsatile mass of the posterior compartment of the leg due to a mycotic aneurysm of the posterior tibial artery. This aneurysm was confirmed by angiography and treated by surgery. The important role of color Doppler sonography for the diagnosis of this particular case is emphasized.
