Question:

Which of the following answer choices is true?
1. Abdominal wall hernias are a rare medical condition.
2. Abdominal wall hernias can be difficult to diagnose due to nonspecific symptoms.
3. Cross sectional imaging is generally not helpful in the diagnosis of an abdominal wall hernia.
4. Abdominal contents rarely protrude through the abdominal wall fascia.
5. Abdominal wall hernias always occur in a similar location.





Answer:

The correct answer for the question "Which of the following answer choices is true?" is:

2. Abdominal wall hernias can be difficult to diagnose due to nonspecific symptoms.



Explanation
1. Abdominal wall hernias are very common. [Abdominal wall hernias are a common surgical problem in the United States with more than one million abdominal wall hernia repairs performed annually.]
2. Abdominal wall hernia symptoms are frequently nonspecific. [Abdominal wall hernias can be difficult to diagnose clinically since symptoms are frequently nonspecific or difficult to localize.]
3. Cross sectional imaging can be very helpful in the diagnosis of an abdominal wall hernia. [Increased utilization of cross-sectional imaging, particularly CT, has dramatically improved diagnosis and subsequent management of patients with other types of abdominal wall hernias such as incisional, inguinal, femoral, and umbilical.]
4. Abdominal contents often protrude through the abdominal wall fascia. [These defects often involve protrusion of abdominal contents through the abdominal wall fascia or musculature.]
5. Abdominal wall hernias occur in many different locations. [Increased utilization of cross-sectional imaging, particularly CT, has dramatically improved diagnosis and subsequent management of patients with other types of abdominal wall hernias such as incisional, inguinal, femoral, and umbilical.]

Abstract
A posterior rectus sheath hernia is an abdominal wall hernia that is rarely encountered. Owing to its rarity, it can be easily overlooked in the setting of a patient presenting with abdominal pain. We report a case of a posterior rectus sheath hernia that caused intermittent small bowel obstruction. The unusual aspects of this case are that the defect was large, measuring 6 cm in the transverse diameter, and that it contained small bowel within a large portion of the rectus sheath. Because the defect was large and affected nearly the entire posterior rectus sheath, it was difficult to discern on computed tomography until a small bowel obstruction developed. In this case, a limited awareness of this clinical entity contributed to the delay in diagnosis.
