病史
47岁女性,慢性肩部疼痛伴急性加重。(A 47-year-old woman with severe acute on chronic shoulder pain.)
影像学表现
MR T1WI(a)和抑脂T2WI(b)显示大结节和冈上肌腱远端明显的低信号(show areas of marked low signal in the greater tuberosity and distal supraspinatus tendon),抑脂T2WI上可见肱骨头和冈上肌腱远端明显水肿并围绕低信号灶(prominent edema in the humeral head and distal supraspinatus tendon is seen surrounding the foci of low signal)。
6个月前的X线片(c)显示冈上肌腱远端邻近大结节处的骨性密度结节(show an ossific density in the distal supraspinatus tendon near the greater tuberosity)。
Calcific tendinitis (resorptive phase) 钙化性肌腱炎(再吸收期)
Trauma 创伤
Surface osteosarcoma 骨表面骨肉瘤
钙化性肌腱炎(再吸收期) Calcific tendinitis (resorptive phase)
由羟基磷灰石晶体在肌腱中沉积所致。Due to deposition of hydroxyapatite crystals in the tendons.
急性临床症状可非常严重,可与感染和创伤相混淆。Acute clinical symptoms can be severe and can mimic infection or trauma.
影像学上,钙化性肌腱炎可与侵袭性病变如感染或肿瘤相混淆。On imaging, calcific tendinitis can mimic aggressive processes such as infection or neoplasm.
为自限性疾病,可予镇痛药对症止痛。Self-limited, with analgesics for pain relief.
可行X线透视或超声引导下经皮针吸和(或)麻醉药物注射。Fluoroscopic or US guided percutaneous needle aspiration and/or injection of anesthestics can be performed.
