case_images: The imaging data of the patient at the age of 45 years old. (A) X-ray showed a lobulated calcified mass in the soft tissues around the right shoulder joint. (B) Axial CT scan showed a lobulated partially calcified mass around the right shoulder joint, some of which demonstrated cysts with sedimentation sign (arrow). (C) MRI showed mixed signal mass in soft tissues around right shoulder joint, some of which also demonstrated cysts with sedimentation sign (arrow). (D) Sagittal planes CT scan showed a lobulated calcified mass around the left elbow joint. (E) coronal planes CT scan showed a lobulated calcified mass around the left wrist joint. (F) SPECT revealed the increased accumulation of radiotracer in the masses of the right shoulder, left elbow and wrist. CT, computed tomography; MRI, magnetic resonance imaging; SPECT, single photon emission computed tomography.

case_images: Single-photon emission computed tomography (SPECT) indicated hypermetabolic lesions located in the right shoulder, left elbow and wrist ( Figure 1 ).
case_images: Postoperative pathology of the mass in right shoulder joint. Pathological examination (hematoxvin-eosin stan): an abundance of calcification was observed to accumulate in the masses (A, x10), with hyperplastic histiocytes and multinucleated giant cells surrounding the calcification (B, x40). Additionally, a substantial amount of fibrous tissue was present between the calcifications (A).
