However, large pedunculated subserosal leiomyomas presenting during early pregnancy are uncommon and may mimic adnexal or intra\u2010abdominal malignancies, posing diagnostic and management challenges. This case presents a rare example of a large pedunculated subserosal leiomyoma in early pregnancy masquerading as a pelvic tumor. This report highlights the diagnostic challenge, intraoperative findings, and successful maternal outcome following timely surgical management. Here we present a case of a 31\u2010year\u2010old G3 P0\u2009+\u20092\u2009L0 woman who presented to our specialty hospital in Northern Tanzania at 11\u2009weeks and 5\u2009days gestational age (GA). She has a history of progressive abdominal distension for 1\u2009year, associated with abdominal pain, vomiting, nausea, and early satiety. Initial abdominal ultrasound evaluation revealed a viable intrauterine pregnancy and a large heterogeneous abdominal mass with increased vascularity on Doppler ultrasound. Magnetic resonance imaging (MRI) identified a 21 \u00d7\u200910 \u00d7\u200915\u2009cm, well\u2010defined encapsulated mass extending intraperitoneally, abutting major abdominal vessels, consistent with a pelvic tumor. Explorative laparotomy revealed this mass to be a pedunculated subserosal fibroid arising from the uterine fundus through a narrow vascular stalk. Myomectomy was successfully performed with minimal blood loss and histopathological examination confirmed a benign leiomyoma with cystic degeneration. The postoperative course was uneventful. Subsequent follow\u2010up at 25\u2009weeks GA showed a viable intrauterine pregnancy with normal fetal growth.<\/jats:p>","DOI":"10.1002\/ccr3.72689","type":"journal-article","created":{"date-parts":[[2026,5,9]],"date-time":"2026-05-09T04:19:49Z","timestamp":1778300389000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A
