A 36-year-old female went to the outpatient clinic of PLA General Hospital for "right hip pain for 3 months". Nearly 1 month before admission, there was severe pain in the right hip joint when walking, and the pain can also be induced when the posture is not appropriate. It is relieved after rest, and there is no hip swelling and fever. Preoperative CT three-dimensional reconstruction showed calcified labrum at the anterolateral margin of the acetabulum (Figure 1, the arrow indicates the calcified labrum). After admission, hip arthroscopy was performed. During the operation, the anterior and upper labrum of the acetabulum was white and full in shape. When the probe hook squeezed the labrum, white calcified deposit overflowed from it in the form of toothpaste (Figure 2). The calcified tissue in the labrum was taken with nucleus pulposus clamp and sent to pathological examination. The pathological results showed a large amount of calcification and a little fat fiber tissue, which was in line with the diagnosis of hip labrum calcification deposition disease (Figure 3). The disease is often manifested as atypical hip pain, which is often aggravated by excessive activity or exertion, but often lacks specific symptoms and signs. Calcification and deposition of hip labrum may exhibit similar features from acetabular fracture and periacetabular free body on CT images. The differentiation of the three requires careful analysis of the location, morphology and relationship with surrounding structures of calcification or free body, combined with the clinical manifestations and medical history of patients. The exact etiology of hip labral calcification deposition disease is not fully understood, and femoroacetabular impingement may be one of the important causes of labral calcification. Hip labral calcification can be treated conservatively with physical therapy and oral non-steroidal anti-inflammatory drugs, and hip arthroscopic surgery can effectively treat hip labral calcification. In this case, the patient had severe hip joint pain, and the anterior and lateral margin of the acetabulum presented a regular high-density shadow. Combined with pathological examination, hip labral calcification deposition disease was confirmed.
