Which condition describes an abnormal spleen location with the liver on the left and stomach on the right, requiring a specific term?

• A. Situs Solitus
• B. Situs Ambiguous
• C. Heterotaxia
• D. Situs Inversus

Answer: (D)

Understanding left-right arrangement of internal organs helps explain why this description fits a specific term. When abdominal organs are a mirror image of normal anatomy—liver on the left and stomach on the right—the body’s visceral layout has reversed from its usual position. This complete mirror-image pattern is known as situs inversus. In the typical full reversal (situs inversus totalis), not only abdominal organs but often the heart is mirrored as well (dextrocardia) and the spleen is on the right. In contrast, normal anatomy is called situs solitus (liver on the right, stomach on the left). A partial or mixed pattern that isn’t a full mirror image is referred to as heterotaxy or situs ambiguous—these describe abnormal arrangements that don’t fit a consistent mirror pattern. So, seeing the liver on the left with the stomach on the right aligns with situs inversus.
