[The use of magnetic resonance imaging in the diagnosis of plantar fibromatosis: a case report].

Abstract

Plantar fibromatosis is a benign but infiltrative neoplasm, presenting as a slow-growing nodular thickening most often within the central band of the plantar aponeurosis. In this case report, we presented a 43-year-old male patient who had a tender nodule in the sole of the right foot for two years. On magnetic resonance images, the location and signal intensity characteristics of the lesion were suggestive of plantar fibromatosis, which was histologically confirmed following an incisional biopsy. Magnetic resonance imaging is a noninvasive method for confirmation of the clinical diagnosis of plantar fibromatosis and also has an important role in planning surgical treatment by delineating the extent of the lesion.
