Fetal lobulation is considered persistent lobulation after which age?

• A. 6
• B. 3
• C. 5
• D. 4

Answer: (C)

Fetal lobulation is a normal variant where the liver surface shows shallow grooves from fetal development. Normally these lobulations smooth out as the liver grows, a process usually completed by about 4 to 5 years of age. If the lobulated contour of the liver persists beyond that age, it is termed persistent fetal lobulation. On imaging, this looks like mild indentations or a lobulated contour but without there being a true mass or cirrhotic change. Since the question asks for the age after which this finding is considered persistent, the commonly accepted threshold is five years. Therefore, five is the correct answer.
