Hydroceles-Not Just For Men.

BACKGROUND: Hydroceles develop in females through the canal of Nuck. This canal is formed when the processes vaginalis fails to obliterate during development. The canal of Nuck can lead to the formation of not only hydroceles, but hernias as well. Although physicians typically think of hydroceles occurring in males, on rare occasions, they do occur in females because of this defect. They are often mistaken for incarcerated hernias, making ultrasound an excellent tool to distinguish between them and guide further treatment. CASE REPORT: We report a rare case of a 46-year-old female with the chief complaint of a painful groin mass. A diagnosis of a hydrocele was made by point of care ultrasonography in the emergency department after being misdiagnosed by computed tomography scan on two previous occasions. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Point of care ultrasound (POCUS) is a valuable tool for emergency physicians and can lead to quick diagnoses and appropriate management of the patient. Using ultrasound in conjunction with other imaging modalities can improve diagnostic accuracy. POCUS is portable and a powerful tool for immediate answers, and continues to prove its utility for clinical decision making.
