Schwannoma mimicking ovarian malignancy
| Summary: | In this article, we present a case of retroperitoneal schwannoma localized in the pelvic cavity mimicking ovarian carcinoma. A 60-year-old woman presented with a feeling of pelvic heaviness and dyspareunia for 3 months. On physical examination, a hardened mass is palpated on the cul-de-sac of Douglas, measuring approximately 10 cm. The sonographic study showed a retro-uterine solid mass, containing cystic areas, measuring 14 cm. Magnetic resonance imaging showed a solid left tumor in the small pelvis, posterior to the uterus, suspicious of an ovarian malign tumor. Surgery revealed a retroperitoneal pelvic tumor and uterus and adnexa without macroscopic changes. Pathology examination of the pelvic mass confirmed the diagnosis of schwannoma. In the present case, it is emphasized that it is easy to misdiagnose a pelvic mass as an ovarian tumor. While prompt recognition of ovarian cancer remains essential, awareness of processes that mimic ovarian tumors can avoid potential misdiagnosis. The pelvis has a complex anatomy and there are some imaging signs that help assessing the origin of a mass, especially in cases of masses abutting the ovary. |
