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 examiner begins scratching in the right lower quadrant of the abdomen along the midclavicular line and moves superiorly until the sound abruptly increases in volume. This location of suddenly increased auscultation volume is marked as the inferior edge of the liver and can then be used to determine the overall liver size.
Abdominal ultrasonography of the liver, as a sagittal plane through the midclavicular line, with some standard measurements [2] Right lobe of the liver at the midclavicular line at ages 0 to 7 [16] Suspicion of hepatomegaly indicates a thorough medical history and physical examination, wherein the latter typically includes an increased liver span.
Liver: Hepatomegaly: Medical imaging: Longitudinal axis > 15.5 cm at the hepatic midline, or > 16.0 cm at the midclavicular line [14] Autopsy: Weight over upper limit of standard reference range, of 1,860 g (4.10 lb) in men [12] and 1,770 g (3.90 lb) in women. [13] Lymph nodes: Lymphadenopathy: Generally 10 mm [15] [16
The vertical lines are the mid-clavicular lines taken from the mid-point of each clavicle. The upper horizontal line is the subcostal line taken from the inferior parts of the lowest costal cartilages. The lower horizontal line is the extoturbular line connecting the tubercles of the pelvis. [3] [4]
Parasternal line: A vertical line equidistant from the sternal and mid-clavicular lines. Mid-clavicular line: A vertical line passing through the midpoint of the clavicle. Mammillary line; Anterior axillary line: A vertical line on the anterior torso marked by the anterior axillary fold.
The bottom line The good news is some causes of chronic inflammation can be treated, but you need to be seen by a physician to pinpoint what’s really going on.
The vertical; or midclavicular lines, are drawn as if dropped from the midpoint of each clavicle. The superior horizontal line is the subcostal line, drawn immediately inferior to the ribs. [1] The inferior horizontal line is called the intertubercular line, and is to cross the iliac tubercles, found at the superior aspect of the pelvis.
