This report describes a unique case of a healthy man in his 30s, who presented with progressive unilateral leg swelling with no common risk factors identified. Two days prior to the swelling he had developed significant abdominal pain following a treadmill exercise session. Ultrasound imaging revealed extensive deep vein thrombosis involving bilateral ileo-femoral venous systems, extending up the inferior vena cava (IVC). Further investigation using a CT venogram revealed the rare congenital anomaly of hypoplasia of the renal IVC. Successful treatment involved 48 hours of an intravenous unfractionated heparin infusion, followed by lifelong anticoagulation.
