A colonic tubulovillous adenoma was incidentally discovered on transvaginal ultrasound in a patient presenting with symptoms suggestive of endometriosis, leading to subsequent colonoscopic diagnosis and polypectomy.

Abstract

Tubulovillous adenomas are colonic polyps with a relatively high potential for malignancy that are typically identified on colonoscopy. We present a case of colonic tubulovillous adenoma first discovered on gynecologic transvaginal ultrasound. The patient was a 42-year-old gravida 2 para 2 female with symptoms suggestive of endometriosis, including left lower quadrant pain, heavy menstrual bleeding, urinary urgency, and dyschezia. The patient underwent transvaginal ultrasound following the International Deep Endometriosis Analysis protocol that identified an intermediate echogenicity, vascular solid mass of the rectosigmoid lumen. Consequent colonoscopy and polypectomy revealed tubulovillous tissue negative for high-grade dysplasia or malignancy. This case report highlights the importance of gynecologists developing an acute awareness of colonic pathologies that might be encountered while performing endometriosis ultrasounds with direct assessment of the rectum.
