Standard anteroposterior and lateral radiographs [Figure 1] showed sharply demarcated lesion, with partially mineralized zones in the periphery, located in the posteromedial soft tissues of the upper arm Ultrasound [Figure 2] confirmed the peripheral calcified lesion in the medial head of the triceps.
Initial ultrasound confirmed the peripheral calcification of the lesion in the medial caput of the triceps. The diameter of the lesion was 1.7 cm

A computed tomography scan [Figure 3] confirmed the tentative diagnosis of MOC because of the presence of peripheral mineralization and perilesional edema.
