Plantar vein thrombosis is an uncommon and under-diagnosed cause of plantar foot pain characterised by the formation of a blood clot (thrombus) within one of the plantar veins. There is no current diagnostic guideline for this condition however compression ultrasound and magnetic resonance imaging appear suitable. Treatments range from rest and non-steroidal anti-inflammatory drugs to six months of anticoagulant therapy. A 51-year old female was referred reporting a two-week history of left heel pain suspicious of plantar fasciitis. Ultrasonography and Magnetic Resonance Imaging showed thickening and expansion of the lateral plantar vein. The patient's symptoms disappeared following two weeks of non-steroidal anti-inflammatory medication and compression therapy, and follow-up ultrasound six weeks later showed recanalisation of the lateral plantar vein.
