What is the likely outcome when the fallopian tube is functioning normally during a hysterosalpingogram?

• A. Contrast is seen in the endometrial cavity
• B. Contrast spills into the peritoneal cavity
• C. Fallopian tube is visible and filled
• D. Uterine cavity shows irregularities

Answer: (B)

In a hysterosalpingogram (HSG), the procedure involves injecting a radiopaque contrast medium into the uterine cavity through the cervix to evaluate the anatomy of the uterus and the patency of the fallopian tubes. When the fallopian tubes are functioning normally, the expected outcome is that the contrast will travel through the tubes and spill out into the peritoneal cavity, indicating that the tubes are open and unobstructed. This is a key diagnostic criterion used to assess female fertility and any potential blockages.

Seeing contrast spill into the peritoneal cavity confirms that the tubes are patent (open), allowing for the possibility of sperm and egg interaction. This scenario enhances the likelihood of conception since a functional fallopian tube is essential for ovum transportation and fertilization.

The presence of contrast in the endometrial cavity suggests proper filling but doesn't confirm tube patency. An irregular uterine cavity would point to possible fibroids, polyps, or other abnormalities and isn’t indicative of normal function, while a visible and filled fallopian tube alone does not address whether the contrast spills into the peritoneum, which is a crucial factor in assessing tube patency. Thus, the correct answer aligns with the expected findings for a normally functioning fall
