False aneurysm of the tibioperoneal trunk as the presenting feature of Behcet's disease

The authors report the case of a 35 year old patient that presented acutely with a false aneurysm of the tibioperoneal trunk diagnosed at Doppler US a nd CT angiography. Behcet's disease was considered because of a prior histo ry of recurrent phlebitis, the presence of bipolar aphthae and a biological inflammatory syndrome. This case is of interest for two reasons: first, the atypical location of t he false aneurysm, and second, the value of less invasive imaging technique s, namely Doppler US and CT angiography.
