Abstract

Endoanal sonography can be used in the assessment of benign and malignant anal conditions and to evaluate the anatomy of the anal sphincters. We used endoanal sonography with a 10‐MHz rotating endocavitary probe to evaluate a 45‐year‐old woman with a perianal mass, fecal incontinence, and menses‐associated perianal pain. She had had 2 vaginal deliveries requiring episiotomies. Biopsy of the mass showed endometrial tissue. The ultrasound examination showed a perianal mass and an external anal sphincter injury. A wide excision and sphincteroplasty were performed, with improvement of fecal continence and pain. Histopathologic examination of the mass confirmed perianal endometrioma in an episiotomy scar. © 2002 Wiley Periodicals, Inc.
