A physician-validated, board-style question from the Active Transport QBank. Try it, then check the reasoning for every option.
A 37-year-old woman comes to the physician because of right-sided inguinal pain for the past 8 weeks. During this period, the patient has had increased pain during activities such as walking and standing. She has no nausea, vomiting, or fever. Her temperature is 36.8°C (98.2°F), pulse is 73/min, and blood pressure is 132/80 mm Hg. The abdomen is soft and nontender. There is a visible and palpable groin protrusion above the inguinal ligament on the right side. Bulging is felt during Valsalva maneuver. Which of the following is the most likely diagnosis?
-
A
LipomaIncorrect. A lipoma is a soft, mobile subcutaneous fatty mass that doesn't change in size with Valsalva and doesn't cause activity-related pain; the Valsalva-responsive bulge here is hernial.
-
B
Indirect inguinal herniaCorrect. A reducible, Valsalva-responsive groin protrusion above the inguinal ligament is most likely an indirect inguinal hernia (the most common type at all ages and in both sexes).
-
C
Inguinal lymphadenopathyIncorrect. Lymphadenopathy presents as a discrete, non-reducible nodule that doesn't change with Valsalva and is not provoked by activity.
-
D
Strangulated herniaIncorrect. Strangulation would present acutely with severe pain, fever, nausea, vomiting, and a non-reducible tender bulge - features absent here in a chronic, reducible presentation.
-
E
Femoral herniaIncorrect. Femoral hernias protrude BELOW the inguinal ligament (medial to the femoral vein) and are more common in women, but the bulge described here is above the inguinal ligament, indicating an inguinal rather than femoral hernia.

Answer: B. A visible and palpable bulge above the inguinal ligament that becomes more prominent with Valsalva, in a patient with chronic activity-related groin pain, defines an inguinal hernia. Inguinal hernias come in two main types:
- Indirect inguinal hernia: protrudes through the internal (deep) inguinal ring, lateral to the inferior epigastric vessels, and passes through the inguinal canal - often extending into the scrotum in men or labia majora in women. It results from a patent processus vaginalis (a congenital defect, though it can present at any age). This is the most common type in both sexes and all ages.
- Direct inguinal hernia: protrudes through Hesselbach's triangle (medial to the inferior epigastric vessels, lateral to the rectus, above the inguinal ligament) due to acquired weakness of the transversalis fascia. More common in older men.
For a 37-year-old woman with a chronic, reducible, activity-related bulge above the inguinal ligament with no signs of strangulation (no severe constant pain, fever, vomiting, or peritonitis), indirect inguinal hernia is the most likely diagnosis. Femoral hernias are also more common in women but classically present below the inguinal ligament.
Clinical pearl: indirect = lateral to inferior epigastrics (mnemonic: "MDs don't LIE" - Medial = Direct, Lateral = Indirect).
**Why each option:**
**A.** A lipoma is a soft, mobile subcutaneous fatty mass that doesn't change in size with Valsalva and doesn't cause activity-related pain; the Valsalva-responsive bulge here is hernial.
**B.** Correct. A reducible, Valsalva-responsive groin protrusion above the inguinal ligament is most likely an indirect inguinal hernia (the most common type at all ages and in both sexes).
**C.** Lymphadenopathy presents as a discrete, non-reducible nodule that doesn't change with Valsalva and is not provoked by activity.
**D.** Strangulation would present acutely with severe pain, fever, nausea, vomiting, and a non-reducible tender bulge - features absent here in a chronic, reducible presentation.
