摘要

目的:假肿瘤是髋关节置换术后罕见的并发症,多见于髋关节,是对植入物中金属颗粒的反应。只有零星的报道,假体植入骨肉瘤患者在保留手术后出现假肿瘤。本研究的目的是介绍假性肿瘤的影像学特征。病例报告:我们报告了一个21岁的男性患者,在治疗股骨骨肉瘤结束3.5年后,在预定的随访超声检查中发现一无痛病变,怀疑在假体和骨残端交界处局部复发。活检标本的组织病理学显示病变为假瘤。结论:虽然假性肿瘤在骨肉瘤患者中是散发性的,但假性肿瘤的生存期较长,可以承受这种并发症的风险。影像学检查,特别是超声检查,可能有助于区分肉瘤的局部复发,然而,在参考中心通过开放活检获得的标本的组织病理学对最终诊断至关重要。

Suspicion of Recurrent Osteosarcoma in a Patient with Pseudotumour Adjacent To the Endoprosthesis.

Suspicion of Recurrent Osteosarcoma in a Patient with Pseudotumour Adjacent To the Endoprosthesis.

Suspicion of Recurrent Osteosarcoma in a Patient with Pseudotumour Adjacent To the Endoprosthesis.

Suspicion of Recurrent Osteosarcoma in a Patient with Pseudotumour Adjacent To the Endoprosthesis.

Purpose: Pseudotumor is a rare complication after arthroplasty, most often of the hip joint, in response to metal particles present in the implant. There are merely sporadic reports of pseudotumor in patients with bone sarcoma after sparing surgery with endoprosthesis implant. The aim of this study is to present the characteristic imaging features of pseudotumor.

Case report: We present a case of a 21-year-old male patient in whom a scheduled follow-up ultrasound revealed a painless lesion suspected of local recurrence at the border of the endoprosthesis and the bone stump 3.5 years after the end of treatment for osteosarcoma of the femur. Histopathology of the biopsy specimen revealed that the lesion was a pseudotumor.

Conclusions: Although pseudotumor is sporadic in patients treated with endoprosthesis for bone sarcoma, their prolonged survival could bear the risk of such a complication. Imaging studies, in particular ultrasound, may be helpful in differentiating from local recurrence of sarcoma, however, the histopathology of the specimen obtained by open biopsy at a reference center is crucial for the final diagnosis.
