Ultrasound revealed bladder\u2010wall thickening and an 8\u2010mm polypoid lesion, suspicious for botryoid\u2010rhabdomyosarcoma. Given the patient's condition, a conservative approach with antibiotics and ultrasound follow\u2010up was adopted. At 12\u2009days, ultrasound demonstrated complete bladder normalization. In selected stable neonates, short\u2010interval US follow\u2010up may support diagnosis through resolution, helping to distinguish inflammatory conditions from malignancy. This approach may reduce unnecessary procedures.\n                  <\/jats:p>","DOI":"10.1002\/jcu.70286","type":"journal-article","created":{"date-parts":[[2026,6,12]],"date-time":"2026-06-12T05:35:39Z","timestamp":1781242539000},"page":"2070-2074","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Diagnosis by Resolution: Ultrasound Follow\u2010Up of Neonatal Polypoid Cystitis Mimicking Botryoid Rhabdomyosarcoma"],"prefix":"10.1002","volume":"54","author":[{"given":"Davide","family":"Meneghesso","sequence":"first","affiliation":[{"name":"UOC Pediatria e Patologia Neonatale Ospedale di Bassano del Grappa  Bassano Del Grappa Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-8250-6653","authenticated-orcid":false,"given":"Mattia","family":"Pasquinucci","sequence":"additional","affiliation":[{"name":"UOC Pediatria e Patologia Neonatale Ospedale di Bassano del Grappa  Bassano Del Grappa Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martina","family":"Bruniera","sequence":"additional","affiliation":[{"name":"UOC Urologia Pediatrica Azienda Ospedale Universit\u00e0 Padova  Padova Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-1848-584X","authenticated-orcid":false,"given":"Filippo","family":"Carletti","sequence":"additional","affiliation":[{"name":"UOC Urologia Pediatrica Azienda Ospedale Universit\u00e0 Padova  Padova Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0201-0758","authenticated-orcid":false,"given":"Alessandro","family":"Morlacco","sequence":"additional","affiliation":[{"name":"UOC Urologia Pediatrica Azienda Ospedale Universit\u00e0 Padova  Padova Italy"},{"name":"DISCOG Universit\u00e0 Degli Studi di Padova  Padova Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,11]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2015.06.040"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/jcm10092028"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.7863\/jum.1994.13.12.921"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1148\/rg.2017170031"}],"container-title":["Journal of Clinical Ultrasound"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jcu.70286","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/jcu.70286","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jcu.70286","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,6]],"date-time":"2026-10-06T17:31:33Z","timestamp":1791307893000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/jcu.70286"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6,11]]},"references-count":4,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2026,10]]}},"alternative-id":["10.1002\/jcu.70286"],"URL":"https:\/\/doi.org\/10.1002\/jcu.70286","archive":["Portico"],"relation":{},"ISSN":["0091-2751","1097-0096"],"issn-type":[{"value":"0091-2751","type":"print"},{"value":"1097-0096","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,6,11]]},"assertion":[{"value":"2026-04-17","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-05-29","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-06-11","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
