Calcific haemorrhagic bursitis anterior to the knee mimicking a soft tissue sarcoma: report of two cases

Skeletal Radiol. 2004 Jun;33(6):363-6. doi: 10.1007/s00256-003-0743-9. Epub 2004 May 1.


We describe the radiological and pathological findings of two cases of calcific haemorrhagic bursitis, one involving the superficial infrapatellar bursa and the other the prepatellar bursa. It was the presence of dystrophic calcification within the lesion that suggested a mineralizing soft tissue sarcoma such as synovial sarcoma. As the radiographic and MR features of the two conditions can be similar but the appropriate management very different, rare calcifying haemorrhagic bursitis needs to be included in the differential diagnosis of masses adjacent to the knee joint showing calcification.
