The patient had experienced these symptoms for many years and was diagnosed with human leukocyte antigen B27\u2013negative spondyloarthritis approximately 11 years prior, based on findings of bilateral erosive sacroiliitis at pelvic radiography and bone scintigraphy with technetium 99m (<jats:sup>99m<\/jats:sup>Tc) methylene diphosphonate. After 3 years of treatment with a tumor necrosis factor\u2013\u03b1 inhibitor (adalimumab), which was effective for pain, the patient was lost to follow-up. At the current presentation, approximately 8 years after being lost to follow-up, the patient presented with worsening low back pain. The presence of nonobstructing kidney stones on US images confounded the underlying cause of worsening pain. The patient also experienced fatigue and depressed mood. Routine blood tests revealed a normal blood cell count, creatinine level of 0.64 mg\/dL (56.58 \u03bcmol\/L) (normal range, 0.30\u20131.1 mg\/dL [26.52\u201397.24 \u03bcmol\/L]), C-reactive protein level of 1.1 mg\/dL (normal, &lt;1 mg\/dL), and vitamin D level of 21 ng\/mL (52.42 nmol\/L) (normal range, 30\u2013100 ng\/mL [74.88\u2013249.60 nmol\/L]). Noncontrast MRI of the thoracic and lumbar spine, MRI of the sacroiliac joints, and CT of the abdomen and pelvis were performed. <\/jats:p><\/jats:sec>","DOI":"10.1148\/radiol.222538","type":"journal-article","created":{"date-parts":[[2024,8,27]],"date-time":"2024-08-27T13:47:37Z","timestamp":1724766457000},"source":"Crossref","is-referenced-by-count":0,"title":["Case 328: Brown Tumor in Hyperparathyroidism Due to Parathyroid Adenoma"],"prefix":"10.1148","volume":"312","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2536-3396","authenticated-orcid":false,"given":"Cristina","family":"Agostinis","sequence":"first","affiliation":[{"name":"From the Department of Neuroradiology (C.A.) and Rheumatology Unit (E.L.), ASST Papa Giovanni XXIII Hospital, Piazza OMS 1, 24124 Bergamo, Italy."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9888-0533","authenticated-orcid":false,"given":"Elide","family":"Lupi","sequence":"additional","affiliation":[{"name":"From the Department of Neuroradiology (C.A.) and Rheumatology Unit (E.L.), ASST Papa Giovanni XXIII Hospital, Piazza OMS 1, 24124 Bergamo, Italy."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1577","reference":[{"key":"r1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(02)08761-5"},{"issue":"1","key":"r2","first-page":"58","volume":"32","author":"Madkhali T","year":"2016","journal-title":"Ulus Cerrahi Derg"},{"key":"r3","doi-asserted-by":"publisher","DOI":"10.1155\/2020\/3146535"},{"key":"r4","doi-asserted-by":"publisher","DOI":"10.1148\/118.2.315"},{"key":"r5","doi-asserted-by":"publisher","DOI":"10.1111\/1756-185X.12527"},{"key":"r6","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.11.7420"},{"key":"r7","doi-asserted-by":"publisher","DOI":"10.1002\/jbmr.5650080915"},{"key":"r8","unstructured":"von Recklinghausen FD.
