In rare instances, calcific tendonitis may manifest in the pediatric population as inflammatory calcium hydroxyapatite deposition. To our knowledge, there have been no previous case reports involving the flexor pollicis longus tendon at the thumb interphalangeal joint. We present a 9-year-old boy with a painful mass at the right thumb interphalangeal joint. Initial radiographs revealed a 7-mm ovoid calcific mass along the volar soft tissues of the thumb interphalangeal joint. Subsequent ultrasound and magnetic resonance findings further confirmed calcification with surrounding edema. Because the pain was limiting the patient's school activities, his family elected for excisional biopsy of the calcific mass. Pathology ultimately revealed prominent dystrophic calcifications with surrounding granulomatous inflammation, consistent with calcific tendonitis.
在罕见情况下，钙化性肌腱炎在儿童人群中可能表现为炎症性羟基磷灰石钙沉积。据我们所知，此前尚无涉及拇指指间关节处拇长屈肌腱的病例报告。我们报告一名9岁男孩，其右拇指指间关节处有一疼痛性肿块。最初的X线片显示沿拇指指间关节掌侧软组织有一个7毫米的椭圆形钙化肿块。随后的超声和磁共振检查结果进一步证实了钙化并伴有周围水肿。由于疼痛限制了患者的学校活动，其家人选择对钙化肿块进行切除活检。病理结果最终显示有明显的营养不良性钙化以及周围的肉芽肿性炎症，符合钙化性肌腱炎。
