A 77 year old man developed bilateral protrusio acetabuli three years following pelvic irradiation for transitional cell carcinoma of the prostatic urethra. There was no evidence of metastasis or coexistent systemic arthritis. Aseptic necrosis of acetabular bone is the postulated etiology. Gross and pathologic evidence of aseptic necrosis of both femoral heads was observed. Vascular fibrosis was a prominent pathologic finding, as was eosinophilia of the synovial fluid and joint tissue. Protrusio appears to be an infrequently described complication of pelvic irradiation.
一名77岁男性在接受前列腺尿道移行细胞癌盆腔放疗三年后出现双侧髋臼突出。没有转移或并存全身性关节炎的证据。推测病因是髋臼骨无菌性坏死。观察到双侧股骨头无菌性坏死的大体和病理证据。血管纤维化是一个突出的病理发现，滑膜液和关节组织的嗜酸性粒细胞增多也是如此。髋臼突出似乎是一种较少被描述的盆腔放疗并发症。
