Figure 2. Plantar fibroma. (a) Ultrasound shows a small well definded hypoechoic mass (arrow) related to the plantar fascia (open arrow). (b) T1 weighted sagittal image and (c) transverse T2 weighted image of a larger lesion showing a mass related to the plantar fascia. The mass returns intermediate signal intensity on T1 and low signal intensity on T2 weighted images.
