Deep venous thrombosis and inferior vena cava agenesis causing double crush sciatic neuropathy in Behçet's disease

We report here the case of a 18-year-old young man with Behçet's disease who had suffered deep venous thrombosis of the right femoral and popliteal veins. Consequently, right sciatic nerve injury, drop foot and tightness of the achilles tendon also ensued. The clinical scenario was further challenged by demonstration of the agenetic inferior vena cava and epidural vein dilatations compressing the lumbar nerve roots. To the best notice of the authors, this is the first patient encompassing all these complications in the literature concerning Behçet's disease.
