Forearm radiographs revealed a 4.3-cm region of calcification within the volar radial soft tissues that was approximately one-third of the length down the forearm (Fig. 1).
A Point-of-care ultrasound imaging taken in the short axis revealed intact muscle belly proximally. B and C Partial tear and calcification at the myotendinous junction. D Intact tendon distally. Dashed line outlines the FCR myotendinous junction.

The FCR tendon and muscle belly proximal and distal to the site of interest were unremarkable (Fig. 2).
Noncontrast T2 weighted magnetic resonance imaging showing calcification about the proximal aspect of the FCR tendon (arrows). A Axial view, B Sagittal view, C Coronal view.

Magnetic resonance imaging demonstrated a lesion consistent with calcification measuring 4.3 x 0.9 x 0.6 cm within the FCR myotendinous junction that was distending the superficial fascia and extending into the thinned subcutaneous tissues (Fig. 3).
Longitudinal incision of the mass revealed calcified tendon at the FCR myotendinous junction.

A longitudinal incision was made that was centered over the defect (Fig. 4).
Dissected tendon from the FCR myotendinous junction. Remaining slip of the tendon is visible in the wound bed.

This remnant was preserved during meticulous dissection of the calcific mass off the underlying scar bed (Figure 5, Figure 6).
