Presentation
right hip pain acceleration
Patient Data
A focus of decreased signal intensity superior to the greater tuberosity along the gluteus medius tendon associated with oedema at gluteus medius muscle and posterosuperior facet of greater tuberosity as well as a small low signal focus at greater tuberosity indicative of hydroxy apatite deposition disease with intraosseous extension in right side are noted.
Degenerative changes at right and left hip joints and tendinosis and partial tear of right gluteus medius tendon are also seen.
Case Discussion
Over the shoulder, the hip is the most common site for HADD. Hydroxy apatite deposits in the hip are most common in the gluteus medius tendon either at the greater trochanter or the acetabulum. The clinical presentation of HADD is more likely from rupture of a calcific deposit into an adjacent soft tissue space or bursa, resulting in an acute inflammatory reaction which called acute calcific periarthritis.
