☀first picture : Computerized tomography of hepatomegaly ☀second picture : Abdomin ultrasonography of the liver • 🌺Definition : Hepatomegaly is the condition of having an enlarged liver. • 🌺Causes : It is a non-specific medical sign having many causes, due to infection, hepatic tumours, or metabolic disorder. • 🌺Syndromes : Often, hepatomegaly will present as an abdominal mass. Depending on the cause, it may sometimes present along with jaundice. • 🌺Diagnosis : On abdominal ultrasonography, : the liver can be measured by the maximum dimension on a sagittal plane view through the midclavicular line ( average = 18 cm in adults "⚡yellow arrow in the picture⚡" ) It is also possible to measure the cranio-caudal dimension (average 15 cm in adults "🔮purple arrow in the picture🔮" ) This can be measured together with the ventro-dorsal dimension (or depth ~ average =13 cm "🎾green arrow in the picture🎾") Also, the caudate lobe is enlarged in many diseases. In the axial plane, the caudate lobe should normally have a cross-section of less than 0.55 of the rest of the liver On CT scan, hepatomegaly has been defined as a longitudinal axis > 15.5 cm at the hepatic midline, or > 16.0 cm at the midclavicular line .
