Case in brief
A multiparous woman was diagnosed with a large pelvic tumor at 18 weeks of gestation. Surgical intervention was postponed until after delivery, and she successfully delivered a healthy term infant vaginally. At 6 weeks postpartum, a laparotomy was performed, revealing a benign retroperitoneal schwannoma upon histopathological examination, a rare finding during pregnancy.
What made this case unusual
The case highlights a benign retroperitoneal schwannoma, which is an uncommon diagnosis in pregnant patients, often mistaken for adnexal masses.
Diagnostic / clinical pearl
Clinicians should consider the possibility of retroperitoneal schwannoma in pregnant patients presenting with pelvic masses, as it may mimic more common adnexal tumors.
Why it matters
This case underscores the importance of careful evaluation and management of pelvic tumors during pregnancy, particularly when malignancy cannot be ruled out.
