A 73-year-old female with a recent history of sclerotherapy and foot pain was being medically treated for plantar fasciitis.
The images above demonstrate filling defect and thrombosis in the lateral plantar vein.
Plantar vein thrombosis is a rare condition with only a few reported cases on ultrasound. There may be two reported cases on MRI. Causes of plantar vein thrombosis include trauma , surgery, paraneoplastic syndrome , hyper coagulable state, use of oral contraceptive, presence of prothrombin gene mutation. The medial and lateral plantar veins course alongside the sole of the foot and join deep to the abductor hallucis muscle forming a single plantar vein adjacent to the medial malleolus to become the posterior tibial vein.
This patient developed plantar vein thrombosis secondary to sclerotherapy.
