Ultrasound is a valuable technique for initial evaluation of pelvic pain in non-pregnant females, which is one of the most common clinical presentations requiring medical evaluation. Although there are a number of abnormalities found during ultrasound assessment that are commonly recognized, such as ruptured ovarian cysts, adnexal torsion, endometriosis, and pelvic inflammatory disease, there are many other potential acute and incidental findings that are uncommonly seen and may not be easily recognized. Recognition of these findings is essential to avoiding delays in diagnosis and management.

Educational Goals / Teaching Points
This exhibit will provide an overview of the spectrum of uncommon findings that may be encountered during ultrasound performed for acute and chronic pelvic pain and provide a framework for categorizing and evaluating these uncommon findings by category: vascular, fluid-containing, and solid.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
We will review ultrasound cases of various entities within the aforementioned categories, such as round ligament varices (vascular), canal of Nuck hydroceles (fluid-containing), and infiltrating endometriosis (solid), with correlative CT and MRI. We will discuss the role of transabdominal, endovaginal, and translabial ultrasound techniques in evaluation of these entities. We will show examples of how to apply specific imaging techniques to aid in diagnosis in specific clinical scenarios (for example, transperineal evaluation of periurethral diverticula and endovaginal evaluation of the appendix and ureterovesical junction stones).

This exhibit reviews uncommon findings detected during the evaluation of pelvic pain in non-pregnant females; provides a framework for differentiating vascular, fluid-containing, and solid structures to narrow the differential; and illustrates unique imaging techniques that may aid in diagnosis.
