Calcific Periarthritis-Plain Film
An adult female with sudden onset juxta articular pain near the MCP joint of digit with no history of trauma. X ray shows subtle soft homogenous and amorphous calcification in the juxta articular location with no significant periarticular demineralization, Soft tissue swelling or widening of the joint, typically favoring acute calcific periarthritis. MRI helps by showing abnormal soft tissue with foci of low signal corresponding to the calcification and exclusion of the differential diagnosis

Acute calcific periarthritis is a form of hydroxyapatite deposition disease with soft amorphous calcification localized to the site of clinical pain particularly in pre and perimenopausal women
· D/D includes Heterotopic calcification/accessory ossicles (presence of cortex and internal trabeculation),CPPD deposits (presence of chondrocalcinosis),Gout (erosions and serum uric acid help),Metastatic periarticular calcification like hyperparathyroidism, Endstage renal disease ,Tumoural calcinosis, and hypervitaminosis etc show multiple sites ,synovial sarcoma(presence of osteoporosis, psammamatous /peripheral calcifications, and extensive soft issue swelling) and of course pyogenic tenosynovitis with no characteristic X ray findings.
