We herein present the case of a 55-year-old woman who suffered from hip pain with subacute onset. She had undergone a hysterectomy-ovariectomy due to endometriosis when she was 41 years old. Her bone mineral density was normal due to supplemental treatment with female hormones. About 3 months after onset, she was referred to our institute with a diagnosis of pelvic bone tumor. Plain radiographs and computed tomography showed irregular osteosclerosis in the para-acetabulum. Bone scintigraphy demonstrated uptake in the para-acetabulum. Magnetic resonance imaging showed abnormal signal with low-signal intensity on T1-weighted images and high-signal intensity on T2-weighted images throughout the entire hemipelvic bone. Since the pain continued for more than 3 months, open biopsy was undertaken and the lesion was found to be non-neoplastic. Six months after onset, the pain disappeared. The clinical course suggested a diagnosis of insufficiency fracture in the para-acetabulum. Para-acetabular insufficiency fractures should always be considered in cases of hip pain, even in patients with prolonged symptoms.<\/jats:p>","DOI":"10.4137\/ccrep.s803","type":"journal-article","created":{"date-parts":[[2017,10,12]],"date-time":"2017-10-12T12:08:55Z","timestamp":1507810135000},"source":"Crossref","is-referenced-by-count":1,"title":["Insufficiency Fracture in the Para-Acetabulum, with Features Mimicking those of a Malignant Bone Tumor"],"prefix":"10.4137","volume":"1","author":[{"given":"Akio","family":"Sakamoto","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takuaki","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuhiro","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuichi","family":"Matsuda","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatsuya","family":"Yoshida","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yukihide","family":"Iwamoto","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2008,6,6]]},"reference":[{"key":"bibr1-CCRep.S803","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.199.1.8633129"},{"key":"bibr2-CCRep.S803","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.159.2.1632335"},{"key":"bibr3-CCRep.S803","doi-asserted-by":"publisher","DOI":"10.1097\/00000421-199406000-00015"},{"key":"bibr4-CCRep.S803","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-002-1562-4"},{"key":"bibr5-CCRep.S803","doi-asserted-by":"publisher","DOI":"10.1080\/028418502127347790"},{"key":"bibr6-CCRep.S803","doi-asserted-by":"publisher","DOI":"10.1007\/BF00198070"},{"key":"bibr7-CCRep.S803","doi-asserted-by":"publisher","DOI":"10.1007\/s002560050200"},{"key":"bibr8-CCRep.S803","doi-asserted-by":"publisher","DOI":"10.1007\/s002560050235"},{"key":"bibr9-CCRep.S803","doi-asserted-by":"publisher","DOI":"10.1007\/BF02207215"},{"key":"bibr10-CCRep.S803","doi-asserted-by":"publisher","DOI":"10.1016\/j.crad.2005.10.003"},{"key":"bibr11-CCRep.S803","doi-asserted-by":"publisher","DOI":"10.1007\/s00256-002-0485-0"}],"container-title":["Clinical Medicine: Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.4137\/CCRep.S803","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.4137\/CCRep.S803","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.4137\/CCRep.S803","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T09:13:25Z","timestamp":1777454005000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.4137\/CCRep.S803"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,1]]},"references-count":11,"alternative-id":["10.4137\/CCRep.S803"],"URL":"https:\/\/doi.org\/10.4137\/ccrep.s803","relation":{},"ISSN":["1178-6450"],"issn-type":[{"value":"1178-6450","type":"print"}],"subject":[],"published":{"date-parts":[[2008,1]]},"article-number":"CCRep.S803"}}
