“…Peripheral and septal contrast enhancement may be seen in the nodules (8). MRI may subdivide PSC in three subtypes according to the classification of Kramer et al (13). The most frequent pattern consists of intra-articular lobules of homogeneous intermediate signal intensity similar to muscle on T1-WI, high signal intensity on T2-WI …”

“…MR appearance can be variable, depending on the degree of calcification and the stage of formation [6]. The most common MRI appearance of synovial chondromatosis is a lobulated T1-isointense and T2-hyperintense mass, with foci of low signal intensity on all sequences corresponding to the calcifications seen on radiographic and CT imaging [7]. Foci of peripheral low signal surrounding central fat-like signal also may be seen, corresponding to areas of ossification [7].…”

A 32-year-old woman presented with onset of progressive left leg pain and swelling after minor trauma 8 weeks previously. Approximately 6 weeks after injury, she was evaluated by a physician at an outside hospital and was prescribed crutches. Imaging studies at that time revealed a calf mass. She then was referred to our orthopaedic clinic for further evaluation. The pain was aggravated by walking, prolonged sitting, or standing. On physical examination, her left calf was tender to palpation and asymmetrically enlarged relative to the contralateral side. A calf mass was palpated. The mass extended from the proximal popliteal fossa down to the lower distal third of the tibia, clinically measured approximately 18 cm, was firm throughout its length, not freely movable from the tibia, and appeared to be deep to the subcutaneous tissue. Radiographic and MR evaluations of the patient's left calf were performed. Based on the history, physical examination, and imaging studies, what is the differential diagnosis? A biopsy of the mass initially was performed 2 months after the onset of symptoms. The initial biopsy sections were interpreted as showing heterotopic ossification without evidence of malignant cells.

“…Recently, however, the MR appearance of synovial osteochondromatosis has also been reported (Kramer et al 1993). Maurice et al (1988), reviewing 53 cases of synovial chondromatosis, found that the mean age at presentation was 48 (17-79) years.…”
