Calcific Tendinitis of the Gluteus Maximums. Do we need to Investigate?

Calcific tendinitis of gluteus maximus is not very common condition and there are only few cases reported till now. . In these patients radiological appearance does mimic malignant changes so we should only investigate these patients if they have significant past medical history i.e. Weight loss, history of malignancy or known primary elsewhere. Calcific tendinitis is quiet common in shoulder mainly distal supraspinatus; other sites have been reported but are rare in occurrence. It can present in two forms either with only amorphous calcification in tendon or calcification of tendon with cortical erosion which can be confusing with metastasis or primary malignant tumour.
