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. [3]
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. [32] Cirrhosis may be suspected from laboratory findings, physical exam, and the person's medical history. Imaging is generally obtained to evaluate the liver. [32]
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 ...
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.
In lymphoma the treatment options include single-agent (or multi-agent) chemotherapy and regional radiotherapy, and surgery is an option in specific situations. Meningococcal group C conjugate vaccine is used in some cases. [23] In primary biliary cirrhosis, ursodeoxycholic acid helps the bloodstream remove bile, which may increase survival. [24]
The liver, viewed from below, surface showing four lobes and the impressions. 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 ...
Congestive hepatopathy, is liver dysfunction due to venous congestion, usually due to congestive heart failure.The gross pathological appearance of a liver affected by chronic passive congestion is "speckled" like a grated nutmeg kernel; the dark spots represent the dilated and congested hepatic venules and small hepatic veins.
The right hepatic vein is the longest and largest of all the hepatic veins. It drains the liver segments VI and VII in their entirety, and variably participates in the drainage of segments V and VIII; the extent of drainage of the latter two segments by the right hepatic veins as opposed to the middle hepatic vein and possible variant accessory veins determines the calibre of the right hepatic ...
