Plantar Fibromatosis: An Unusual Cause of Plantar Pain

Abstract

On physical examination, he had subcutaneous nodules on the medial aspect of the plantar surface of the feet, more voluminous on the right. The patient was otherwise healthy and vital signs and laboratory tests were unremarkable.Radiographs demonstrated absence of underlining bone disease. An ultrasound was performed and revealed bilateral hypoechoic nodules located in the distal part of the central bundle of the plantar fascia, which presented slight color Doppler flow. On MRI the nodules were iso to hypointense on T1 and T2-weighted images owing to their fibrous nature, hyperintense on STIR images and showed enhancement after contrast injection (Figure 1).
