Med."],"abstract":"\n Background<\/jats:title>\n \n Hydatid cyst is a zoonotic infection caused by the larval stage of\n Echinococcus granulosus<\/jats:italic>\n . While the lungs are frequently affected, rib involvement and chest wall invasion are extremely rare, occurring in less than 2.5% of cases. We report a rare case of recurrent hydatid disease exhibiting infiltrative growth into the costal trabeculae and lung parenchyma.\n <\/jats:p>\n <\/jats:sec>\n \n Case presentation<\/jats:title>\n \n A 50-year-old man presented with weight loss. He had a history of splenectomy for hydatid disease 14\u202fyears prior. Physical examination and blood tests were unremarkable; however, chest computed tomography (CT) revealed a 56\u202f\u00d7\u202f52\u202fmm multilocular cystic lesion in the apico-posterior segment of the left lung, causing destruction of the second, third, and fourth ribs. Immunoglobulin hemagglutination was positive (1\/256). During left posterolateral thoracotomy, an 8\u202f\u00d7\u202f6\u202fcm lesion was found prolapsing through the intercostal space. Due to the lack of a clear cleavage plane in the parenchyma and extensive rib destruction, an en bloc resection was performed, including a pulmonary wedge resection and partial resection of the three affected ribs. Histopathology confirmed the diagnosis of a hydatid cyst with daughter cysts and bone trabeculae involvement. The patient was discharged on the 10\n th<\/jats:sup>\n postoperative day without complications and started on albendazole (800\u202fmg\/day).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n This case demonstrates that hydatid cysts can recur many years after the initial surgery and may exhibit an atypical, infiltrative progression into neighboring tissues, including bone. While parenchyma-preserving surgery is the standard, radical en bloc resection may be necessary for curative treatment in cases of chest wall invasion. Long-term postoperative antihelmintic therapy is essential to prevent further recurrence.<\/jats:p>\n <\/jats:sec>","DOI":"10.3389\/fmed.2026.1808294","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T05:37:58Z","timestamp":1777527478000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["A rare recurrence of hydatid cyst with chest wall invasion: a case report"],"prefix":"10.3389","volume":"13","author":[{"given":"H\u00fcseyin","family":"\u00c7akmak","sequence":"first","affiliation":[{"name":"Department of Thoracic Surgery, Dr. Abdurrahman Yurtaslan Ankara Onkoloji Research and Training Hospital","place":["Ankara, T\u00fcrkiye"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,4,30]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1128\/cmr.00075-18","article-title":"Echinococcosis: advances in the 21st century","volume":"32","author":"Wen","year":"2019","journal-title":"Clin Microbiol Rev"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"485","DOI":"10.1089\/sur.2020.197","article-title":"Pulmonary echinococcosis or lung hydatidosis: a narrative review","volume":"22","author":"Lupia","year":"2021","journal-title":"Surg Infect"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"61","DOI":"10.1080\/08941930500444586","article-title":"Parenchyma-preserving surgery in the management of pulmonary hydatid cysts","volume":"19","author":"Kavuk\u00e7u","year":"2006","journal-title":"J InvestSurg"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"1277","DOI":"10.1378\/chest.105.4.1277","article-title":"Chest wall echinococcosis","volume":"105","author":"Ozdemir","year":"1994","journal-title":"Chest"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"306","DOI":"10.1016\/j.rmr.2011.02.003","article-title":"Hydatidose costale [hydatid disease of the ribs]","volume":"28","author":"Ouadnouni","year":"2011","journal-title":"Rev Mal Respir"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"492","DOI":"10.5761\/atcs.cr.14-00337","article-title":"Cystic hydatidosis of the rib-case report and review of the literature","volume":"21","author":"Roman","year":"2015","journal-title":"Ann ThoracCardiovascSurg"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"49","DOI":"10.1007\/s13304-011-0127-y","article-title":"Costal hydatidosis: management and outcome of five cases","volume":"64","author":"El Oueriachi","year":"2012","journal-title":"UpdatesSurg"}],"container-title":["Frontiers in Medicine"],"original-title":[],"link":[{"URL":"https:\/\/www.frontiersin.org\/articles\/10.3389\/fmed.2026.1808294\/full","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T05:37:59Z","timestamp":1777527479000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.frontiersin.org\/articles\/10.3389\/fmed.2026.1808294\/full"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,4,30]]},"references-count":7,"alternative-id":["10.3389\/fmed.2026.1808294"],"URL":"https:\/\/doi.org\/10.3389\/fmed.2026.1808294","relation":{},"ISSN":["2296-858X"],"issn-type":[{"value":"2296-858X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,4,30]]},"article-number":"1808294"}}
