Anatomy · Inguinal region
Sample itemA firm swelling is felt in the groin below and lateral to the pubic tubercle. What is the most likely diagnosis?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. Femoral hernia
Inguinal hernias lie above and medial to the pubic tubercle, femoral hernias below and lateral to it. The femoral ring is narrow and rigid, so these hernias are prone to strangulation and are commoner in women.
Option by option
A. Obturator hernia
Obturator hernias pass through the obturator canal and rarely present as a groin lump.
B. Femoral hernia (correct)
Correct. The femoral canal opens below the inguinal ligament, lateral to the pubic tubercle.
C. Indirect inguinal hernia
Indirect hernias enter the deep ring above the ligament and may reach the scrotum.
D. Direct inguinal hernia
Direct hernias bulge above the inguinal ligament, medial to the inferior epigastric vessels.
