Diffuse pulmonary uptake, classically linked to metastatic calcification, is commonly observed in chronic kidney disease patients with calcium-phosphate homeostasis disruption.

While thoracic computed tomography showed no structural abnormalities, bone scintigraphy demonstrated diffuse pulmonary radiotracer accumulation, consistent with metastatic calcification secondary to calcium-phosphate deposition within alveolar walls. This case underscores the critical need for vigilant monitoring of metabolic complications in oncology patients, especially those with renal impairment, and highlights the diagnostic value of bone scintigraphy in identifying occult extraskeletal pathologies, even when conventional imaging appears unremarkable. The findings advocate for integrating metabolic profiling with functional imaging to better understand atypical tracer uptake patterns in high-risk populations.\n                  <\/jats:p>","DOI":"10.4103\/ijnm.ijnm_19_25","type":"journal-article","created":{"date-parts":[[2025,6,30]],"date-time":"2025-06-30T02:00:49Z","timestamp":1751248849000},"page":"120-121","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Diffuse Pulmonary 99mTc-MDP Uptake on Bone Scintigraphy: A Paraneoplastic Hypercalcemia Clue in Cervical Carcinoma"],"prefix":"10.25259","volume":"40","author":[{"given":"Ikram","family":"Zahfir","sequence":"first","affiliation":[{"name":"Department of Nuclear Medicine, Mohammed V Military Teaching Hospital, Rabat, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yassir","family":"Benameur","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Mohammed V Military Teaching Hospital, Rabat, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meryem","family":"Aboussabr","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Mohammed V Military Teaching Hospital, Rabat, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salah Nabih","family":"Oueriagli","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Mohammed V Military Teaching Hospital, Rabat, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Omar Ait","family":"Sahel","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Mohammed V Military Teaching Hospital, Rabat, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abderrahim","family":"Doudouh","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Mohammed V Military Teaching Hospital, Rabat, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10894","published-online":{"date-parts":[[2025,6,27]]},"reference":[{"key":"R1-20250701","doi-asserted-by":"crossref","first-page":"160","DOI":"10.2214\/AJR.14.13914","article-title":"Extraosseous findings on bone scintigraphy using fusion SPECT\/CT and correlative imaging","volume":"205","author":"Wale","year":"2015","journal-title":"Am J Roentgenol"},{"key":"R2-20250701","first-page":"403","article-title":"Soft tissue calcification in chronic dialysis patients","volume":"86","author":"Kuzela","year":"1977","journal-title":"Am J Pathol"},{"key":"R3-20250701","doi-asserted-by":"crossref","first-page":"549","DOI":"10.1677\/erc.1.00543","article-title":"Hypercalcaemia of malignancy and basic research on mechanisms responsible for osteolytic and osteoblastic metastasis to bone","volume":"12","author":"Clines","year":"2005","journal-title":"Endocr Relat Cancer"},{"key":"R4-20250701","doi-asserted-by":"crossref","first-page":"275","DOI":"10.4103\/0972-3919.158546","article-title":"Pulmonary calcification in renal failure patient incidentally revealed by bone scintigraphy","volume":"30","author":"Sellem","year":"2015","journal-title":"Indian J Nucl Med"}],"container-title":["Indian Journal of Nuclear Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.lww.com\/10.4103\/ijnm.ijnm_19_25","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,25]],"date-time":"2026-05-25T07:38:27Z","timestamp":1779694707000},"score":1,"resource":{"primary":{"URL":"https:\/\/ijnm.co.in\/diffuse-pulmonary-99mtc-mdp-uptake-on-bone-scintigraphy-a-paraneoplastic-hypercalcemia-clue-in-cervical-carcinoma\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,3]]},"references-count":4,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.4103\/ijnm.ijnm_19_25","relation":{},"ISSN":["0972-3919","0974-0244"],"issn-type":[{"value":"0972-3919","type":"print"},{"value":"0974-0244","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,3]]},"assertion":[{"value":"2025-02-09","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-03-11","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
