Liver and Biliary Pathology Practice Questions

Q: Von-Meyenburg's complexes are typically found in which organ?

Liver. **Explanation:** **Von-Meyenburg Complexes (VMCs)**, also known as **biliary hamartomas**, are small, benign malformations of the intrahepatic bile ducts [1]. They occur due to the failure of the embryonic ductal plate to remodel during development [1]. 1. **Why Liver is Correct:** VMCs are specifically located in the **liver**. Histologically, they consist of clusters of dilated, irregular, or angulated bile ducts embedded in a dense fibrocollous stroma [1]. These ducts are lined by a single layer of cuboidal biliary epithelium and often contain "bile plugs" or proteinaceous material. While usually asymptomatic and discovered incidentally, they are important because they can mimic metastatic disease on imaging (appearing as multiple small, subcapsular hypoechoic nodules). 2. **Why Other Options are Incorrect:** * **Brain:** Common congenital lesions include hamartomas (e.g., in Tuberous Sclerosis), but VMCs are not found here. * **Kidney:** While VMCs are associated with **Autosomal Dominant Polycystic Kidney Disease (ADPKD)** and Polycystic Liver Disease [1], the complexes themselves are hepatic lesions, not renal. * **Spleen:** Splenic hamartomas exist (splenomas), but they are composed of red pulp elements, not biliary structures. **High-Yield Clinical Pearls for NEET-PG:** * **Association:** VMCs are part of the spectrum of **Fibropolycystic Liver Diseases**, which includes Caroli disease and Congenital Hepatic Fibrosis [1]. * **Imaging:** On MRI, they appear as "starry sky" patterns (multiple small hyperintense lesions on T2-weighted images). * **Malignant Potential:** Though benign, they are rarely considered precursors to **cholangiocarcinoma**. **References:** [1] Kumar V, Abbas AK, et al..

Question 3

In chronic inflammation confined to portal tract with intact limiting membrane and normal lobular parenchyma, what is the histopathological diagnosis?

Accepted Answer

Chronic persistent hepatitis

Answer

Active hepatitis

Answer

Chronic active hepatitis

Answer

Alcoholic hepatitis

Question 4

In post-hepatic jaundice, the concentration of conjugated bilirubin in the blood is higher than that of unconjugated bilirubin because:

Accepted Answer

The conjugation process of bilirubin in the liver remains operative without any interference.

Answer

There is an increased rate of destruction of red blood cells.

Answer

The unconjugated bilirubin is trapped by the bile stone produced in the bile duct.

Answer

The UDP-glucuronosyltransferase activity is increased manifold in obstructive jaundice.

Question 5

In chronic viral hepatitis, what does grading refer to?

Accepted Answer

Grading refers to the extent of necrosis and inflammation.

Answer

Hepatitis A virus infection is a common cause in children.

Answer

Morphological classification into Chronic Active Hepatitis and Chronic Persistent Hepatitis is important.

Answer

Fatty change is pathognomic of Hepatitis C virus infection.
