The liver span is a measurement performed during physical examination to determine the size of the liver and identify possible hepatomegaly.. It is the distance between the lower border of the liver in the mid-clavicular line obtained by palpation, and the upper border of the liver in the mid-clavicular line detected by percussion (the upper border of the liver lies behind the ribs and can not ...
The liver scratch test can be used when other exam techniques used to approximate liver size are ineffective or unavailable [2] and is thought to be most useful if the abdomen is distended, too tender for direct palpation, the abdominal muscles are too rigid, or the patient is obese. [3]
On light palpation, the examiner tests for any palpable mass, rigidity, or pain on the surface. On deep palpation, the examiner is testing for any organomegaly (enlarged organs.) Typically, the clinician is looking for enlargement of the liver and spleen or abnormal masses in the intestines.
Murphy's sign has a high sensitivity and negative predictive value, although the specificity is not high. [2] However, in the elderly the sensitivity is markedly lower; a negative Murphy's sign in an elderly person is not useful for ruling out cholecystitis if other tests and the clinical history suggest the diagnosis.
There is usually also tenderness on palpation of the right upper abdomen and tenderness to percussion of the lower ribs which protect the liver. Patients may also report fevers, malaise, back pain, pelvic pain, dyspareunia, vaginal discharge, and dysuria. [13] [14] Patients are most often women of childbearing age.
Suspicion of hepatomegaly indicates a thorough medical history and physical examination, wherein the latter typically includes an increased liver span. [citation needed] On abdominal ultrasonography, the liver can be measured by the maximum dimension on a sagittal plane view through the midclavicular line, which is normally up to 18 cm in ...

A genetic disorder causing multiple cysts to form in the liver tissue, usually in later life, and usually asymptomatic, is polycystic liver disease. Diseases that interfere with liver function will lead to derangement of these processes. However, the liver has a great capacity to regenerate and has a large reserve capacity. In most cases, the ...
