A liver measurement greater than what range is considered hepatomegaly?

Hepatomegaly, or an enlarged liver, is clinically indicated when the liver measurement exceeds certain thresholds. Typically, a normal adult liver size is considered to be up to about 15 cm along the longest dimension when measured via ultrasound. A measurement greater than 15 cm is generally classified as hepatomegaly. This is significant because hepatomegaly can be associated with various underlying conditions, including liver disease, heart failure, and metabolic disorders.

The range indicated in the correct answer encompasses the threshold that defines hepatomegaly well. Measurements approaching or exceeding 20 cm indicate significant enlargement and can often raise concern for serious pathology. Therefore, the choice that effectively marks this critical transition point in liver size is defined as greater than 15 cm, making it accurate for recognizing hepatomegaly. Furthermore, knowledge about the normal liver size and understanding the implications of hepatomegaly is crucial for diagnosis and management in clinical practice.
