Recently, a balloon catheter to dilate peripheral bronchi has become commercially available, offering a potential solution to this limitation. This is a case of a 73\u2010year\u2010old female nonsmoker with rheumatoid arthritis on Tacrolimus. Chest CT scan showed a 13.9\u2010mm pure GGN at the right upper lobe. Annual chest CT scan noted stability in size for 7\u2009years, but recently the size increased to 17.0\u2009mm with a positive bronchus sign in the 12th generation. An ultrathin bronchoscope could be inserted up to the 9th generation. Balloon dilatation was done at this point to pass the subsequent tortuous bifurcation, advancing the bronchoscope further up to the 10th generation. Where radial endobronchial ultrasound showed a blizzard sign, cryobiopsy was performed, revealing lung adenocarcinoma. This case highlights the value of balloon dilatation and cryobiopsy for ultra\u2010peripheral GGNs.<\/jats:p>","DOI":"10.1002\/rcr2.70409","type":"journal-article","created":{"date-parts":[[2025,11,11]],"date-time":"2025-11-11T23:19:19Z","timestamp":1762903159000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Balloon Dilatation and Cryobiopsy on an Ultra\u2010Peripheral Ground Glass Nodule: A Case Report"],"prefix":"10.1002","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-4817-8547","authenticated-orcid":false,"given":"Ria Katrina","family":"Cortez","sequence":"first","affiliation":[{"name":"Department of Endoscopy, Respiratory Endoscopy Division National Cancer Center Hospital  Tokyo Japan"},{"name":"Department of Internal Medicine South Cotabato Provincial Hospital  Koronadal City South Cotabato Philippines"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuji","family":"Matsumoto","sequence":"additional","affiliation":[{"name":"Department of Endoscopy, Respiratory Endoscopy Division National Cancer Center Hospital  Tokyo Japan"},{"name":"Department of Thoracic Oncology National Cancer Center Hospital  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9327-5155","authenticated-orcid":false,"given":"Hideaki","family":"Furuse","sequence":"additional","affiliation":[{"name":"Department of Endoscopy, Respiratory Endoscopy Division National Cancer Center Hospital  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-1232-0126","authenticated-orcid":false,"given":"Kenya","family":"Sato","sequence":"additional","affiliation":[{"name":"Department of Endoscopy, Respiratory Endoscopy Division National Cancer Center Hospital  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takaaki","family":"Tsuchida","sequence":"additional","affiliation":[{"name":"Department of Endoscopy, Respiratory Endoscopy Division National Cancer Center Hospital  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,11,11]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/17476348.2024.2387089"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1159\/000536666"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00167914"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.21037\/tlcr\u201020\u2010957"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.21037\/tlcr\u201024\u2010304"}],"container-title":["Respirology Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/rcr2.70409","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,11,26]],"date-time":"2025-11-26T04:38:10Z","timestamp":1764131890000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/rcr2.70409"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,11]]},"references-count":5,"journal-issue":{"issue":"11","published-print":{"date-parts":[[2025,11]]}},"alternative-id":["10.1002\/rcr2.70409"],"URL":"https:\/\/doi.org\/10.1002\/rcr2.70409","archive":["Portico"],"relation":{},"ISSN":["2051-3380","2051-3380"],"issn-type":[{"value":"2051-3380","type":"print"},{"value":"2051-3380","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,11]]},"assertion":[{"value":"2025-07-28","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-10-30","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-11-11","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70409"}}
