Uterine souffle is defined as
**Core Concept**
Uterine souffle, also known as uterine bruit, is a vascular sound heard over the uterus, typically indicative of abnormal blood flow or a vascular anomaly.
**Why the Correct Answer is Right**
A uterine souffle is caused by turbulent blood flow through a vascular malformation or an abnormal communication between the uterine arteries and the veins. This abnormal flow creates a high-velocity jet of blood, which produces a characteristic sound. The sound is often described as a bruit, which is a vascular murmur or whooshing sound, typically heard with a stethoscope.
**Why Each Wrong Option is Incorrect**
**Option A:** A uterine souffle is not a symptom of uterine cancer. While cancer can cause a variety of symptoms, a souffle is a specific sign of abnormal blood flow, not tumor growth.
**Option B:** A uterine souffle is not a normal finding during pregnancy. While some changes in blood flow occur during pregnancy, a souffle is an abnormal sign that requires further investigation.
**Option C:** A uterine souffle is not a sign of pelvic inflammatory disease (PID). While PID can cause pelvic pain and other symptoms, a souffle is a specific sign of abnormal blood flow, not infection.
**Clinical Pearl / High-Yield Fact**
A uterine souffle can be a sign of a vascular anomaly, such as a uterine arteriovenous malformation (AVM). These malformations can be congenital or acquired and can cause a variety of symptoms, including bleeding, pain, and abnormal uterine bleeding.
**Correct Answer:** D. Uterine bruit or abnormal blood flow.
