Ultrasound in the diagnosis and management of plantar fibromatosis (ledderhose disease): A case report

Plantar fibromatosis, also known as Ledderhose disease, is a rare benign fibroproliferative disorder of the plantar fascia, characterized by the development of slowly growing nodules that may become painful and functionally limiting. Although the diagnosis is often suspected clinically, imaging-particularly ultrasound-plays an important role in confirming the diagnosis and guiding management. We report the case of a 57-year-old man presenting with bilateral plantar nodules, in whom ultrasound enabled diagnostic confirmation and guided corticosteroid injection. Conservative management combining ultrasound-guided injection, custom orthotic insoles, and a targeted rehabilitation program resulted in complete pain relief and a reduction in nodule size at short-term follow-up. This case illustrates the diagnostic and interventional value of ultrasound in the nonsurgical management of plantar fibromatosis.
