A 36-year-old man presents to you complaining of right scrotal swelling. He states that the swelling has been present for 1 week. He initially noticed the swelling sholy after moving furniture for his new living room. He denies any nausea, vomiting, change in bowel habits, abdominal pain, or urinary tract symptoms. He has no other significant medical or surgical history. On examination, he has an enlarged right hemi-scrotum with a mass that appears to be originating at the level of the external inguinal ring. With the patient completely relaxed, the physician is able to reduce the mass by pushing it back through the external inguinal ring. With the mass reduced, the physician instructs the patient to perform a Valsalva maneuver, upon which a protrusion is felt at the external inguinal ring. Once the mass is reduced, the testicle appears normal in size and consistency. Which of the following is the most likely diagnosis?

💡 Explanation
**Core Concept**
The patient is likely suffering from a condition that involves the herniation of abdominal contents through a congenital or acquired defect in the posterior wall of the inguinal canal, which is exacerbated by increased intra-abdominal pressure.
**Why the Correct Answer is Right**
The patient's symptoms and physical examination findings are consistent with an indirect inguinal hernia. The mass is reducible and originates at the level of the external inguinal ring, which is a characteristic feature of indirect inguinal hernias. The Valsalva maneuver, which increases intra-abdominal pressure, causes the hernia to protrude through the external inguinal ring. The fact that the testicle appears normal in size and consistency after the mass is reduced also supports this diagnosis.
**Why Each Wrong Option is Incorrect**
* **Option A:** A femoral hernia would typically present as a bulge in the upper medial aspect of the thigh, not in the inguinal region.
* **Option B:** A hydrocele is an accumulation of fluid in the tunica vaginalis, which would not be reducible and would not be exacerbated by a Valsalva maneuver.
* **Option D:** A varicocele is an enlargement of the pampiniform plexus of veins, which would not be reducible and would not be exacerbated by a Valsalva maneuver.
**Clinical Pearl / High-Yield Fact**
The "sliding hernia" sign, where the hernia sac is continuous with the peritoneal sac, is a key feature of indirect inguinal hernias. This sign can be elicited by asking the patient to cough or perform a Valsalva maneuver while the hernia is reduced.
**Correct Answer:** C. Indirect inguinal hernia.
✓ Correct Answer: C. Inguinal hernia
