Caudate lobe hypertrophy on ultrasound due to cirrhosis Hepatofugal (non-forward) flow in portal vein. The diagnosis of cirrhosis in an individual is based on multiple factors. [33] Cirrhosis may be suspected from laboratory findings, physical exam, and the person's medical history. Imaging is generally obtained to evaluate the liver. [33]
Caudate lobe enlargement is often present. The majority of patients have a slower-onset form of Budd–Chiari syndrome. This can be painless. A system of venous collaterals may form around the occlusion which may be seen on imaging as a "spider's web". Patients may progress to cirrhosis and show signs of liver failure. [5]
The caudate process is a small elevation of the hepatic substance extending obliquely and laterally, from the lower extremity of the caudate lobe to the undersurface of the right lobe. The caudate lobe has a complex blood supply system. It derives its arterial supply from the caudate arteries, which arise from the right, left, and middle ...
This can be measured together with the ventro-dorsal dimension (or depth), which is normally up to 13 cm. [2] 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. [2]
A hot quadrate sign is an imaging appearance of increased enhancement in CT scans or MRI, or radiotracer accumulation in nuclear medicine, in which there is enhancement of the quadrate lobe of the liver.
Signs and symptoms depend largely upon the primary lesions giving rise to the condition. In addition to the heart or lung symptoms, there will be a sense of fullness and tenderness in the right hypochondriac region. Gastrointestinal catarrh is usually present, and vomiting of blood may occur. There is usually more or less jaundice.
The exact cause is not always known, but it may occur in patients with a long and mobile colon (dolichocolon), chronic lung disease such as emphysema, or liver problems such as cirrhosis and ascites. Chilaiditi's sign is generally not associated with symptoms, and is most commonly an incidental finding in normal individuals.
The liver is grossly divided into two parts when viewed from above – a right and a left lobe – and four parts when viewed from below (left, right, caudate, and quadrate lobes). [16] The falciform ligament makes a superficial division of the liver into a left and right lobe. From below, the two additional lobes are located between the right ...
