Hepatomegaly is enlargement of the liver. [4] It is a non-specific medical sign , having many causes, which can broadly be broken down into infection , hepatic tumours , and metabolic disorder . Often, hepatomegaly presents as an abdominal mass .
The transverse plane (also known as the horizontal plane, axial plane and transaxial plane) is an anatomical plane that divides the body into superior and inferior sections. [1] It is perpendicular to the coronal and sagittal planes.
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
A sagittal plane (also known as anteroposterior plane) is perpendicular to the ground, separating left from right. The median (or midsagittal) plane is the sagittal plane in the middle of the body; it passes through midline structures such as the navel and the spine. All other sagittal planes (also known as parasagittal planes) are parallel to it.
Anatomical planes in a human. Anatomical terms describe structures with relation to four main anatomical planes: [2] The median plane, which divides the body into left and right. [2] [6] This passes through the head, spinal cord, navel, and, in many animals, the tail. [6] The sagittal planes, which are parallel to the median plane. [1]
The liver is a major metabolic organ exclusively found in vertebrate animals, which performs many essential biological functions such as detoxification of the organism, and the synthesis of proteins and various other biochemicals necessary for digestion and growth.
The alternate spelling Frankfort plane is also widely used, and found in several medical dictionaries, although Frankfurt is the modern standard spelling of the city it is named for. Another name for the plane is the auriculo-orbital plane. Note that in the normal subject, both orbitales and both porions lie in a single plane.
The axial surface is defined as a plane connecting all the hinge lines of stacked folded surfaces. If the axial surface is planar, it is called an axial plane and can be described in terms of strike and dip. Folds can have a fold axis.
