Exophytic variants can mimic gynecological or mesenchymal pelvic masses, posing diagnostic challenges. Accurate preoperative recognition is crucial to avoid perioperative complications, especially in functional cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case<\/jats:title>\n                    <jats:p>A 22\u2010year\u2010old asymptomatic woman presented with a slowly enlarging pelvic mass. Transrectal contrast\u2010enhanced ultrasound (CEUS) revealed rapid, intense homogeneous early enhancement with late peripheral rim enhancement. MRI showed a markedly T2\u2010hyperintense parauterine mass with vivid enhancement and restricted diffusion. The mass was intraoperatively confirmed to originate from the posterior bladder wall. Partial cystectomy was performed, and histopathology confirmed paraganglioma with malignant potential.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Exophytic UBPGL can mimic common pelvic tumors. Multimodality imaging, including CEUS and MRI, plays a key role in characterizing vascularity and guiding surgical planning, though diagnosis ultimately relies on histopathology and clinical correlation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/jcu.70370","type":"journal-article","created":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T04:39:47Z","timestamp":1786077587000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Imaging Findings of an Exophytic Urinary Bladder Paraganglioma Mimicking a Gynecological Mass: A Case Report"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2490-3525","authenticated-orcid":false,"given":"Jing","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Ultrasound West China Second University Hospital, Sichuan University  Chengdu Sichuan China"},{"name":"Key Laboratory of Birth Defects and Related Diseases of Women and Children (Sichuan University), Ministry of Education  Chengdu Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Cai","sequence":"additional","affiliation":[{"name":"Department of Infectious Disease West China Longquan Hospital Sichuan University\/the First People's Hospital of Longquanyi District Chengdu  Chengdu Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Jiang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Birth Defects and Related Diseases of Women and Children (Sichuan University), Ministry of Education  Chengdu Sichuan China"},{"name":"Department of Pathology West China Second University Hospital, Sichuan University  Chengdu Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-1225-9992","authenticated-orcid":false,"given":"Tian","family":"Tian","sequence":"additional","affiliation":[{"name":"Department of Ultrasound West China Second University Hospital, Sichuan University  Chengdu Sichuan China"},{"name":"Key Laboratory of Birth Defects and Related Diseases of Women and Children (Sichuan University), Ministry of Education  Chengdu Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,6]]},"reference":[{"issue":"8","key":"e_1_2_8_2_1","doi-asserted-by":"crossref","first-page":"3791","DOI":"10.1016\/j.asjsur.2024.04.131","article-title":"Multi\u2010Modality Imaging of the Urinary Bladder Paraganglioma: A Rare Case Report","volume":"47","author":"Chen S.
