Analysis of Clinical and Imaging Findings of Tumoral Calcinosis

Objective:To study the clinical and imaging manifestations of tumoral calcinosis,so as to improve the accuracy of imaging diagnosis.Methods:The clinical and imaging materials of 6 patients with surgery and pathology proved tumoral calcinosis were retrospectively analyzed.All 6 patients had radiography,2 patients had MRI.Results:The clinical findings of these 6 patients were painless mass adjacent to joint,with multiple masses in 2 patients and solitary mass in 4 patients.Conglomerate calcified mass could be assessed in the peri-articular soft tissue by radiography.On MRI,nodular heterogeneous hypo-intensities could be seen on T1WI and hyper-intensities on T2WI.No abnormalities could be revealed in the adjacent joint structure both on radiography or MRI.Conclusion:The typical imaging features of tumoral calcinosis were multiple calcified masses in the peri-articular soft tissue with intact articular structures.Radiography and MRI are helpful in the diagnosis and differentiate diagnosis.
