Hepatitis01:25

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
Hepatic Portal System01:21

Hepatic Portal System

The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is responsible...
Hepatic Encephalopathy01:29

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
Symbiosis00:58

Symbiosis

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Summary

Visceral larva migrans (VLM) is an underdiagnosed parasitic infection. This report details subtle hepatic imaging findings of VLM, aiding diagnosis in developing countries.

Area of Science:

  • Medical Imaging
  • Parasitology
  • Hepatology

Background:

  • Visceral larva migrans (VLM) involves nematode larvae migrating through human visceral tissues.
  • VLM is frequently underdiagnosed, particularly in developing nations.
  • The liver is the most commonly affected organ due to its rich portal blood supply.

Observation:

  • Hepatic lesions in VLM present subtle imaging features.
  • Distinguishing VLM from hepatocellular carcinoma (HCC), metastases, and other conditions is challenging.
  • This case report focuses on the imaging characteristics of hepatic VLM.

Findings:

  • The study highlights specific imaging findings associated with hepatic VLM.
  • Integration of clinical and laboratory data is crucial for accurate diagnosis.

  • Subtle imaging findings can mimic other hepatic pathologies.

    • Implications:

    • Improved recognition of VLM imaging features can enhance early diagnosis.
    • Accurate diagnosis of VLM is essential for appropriate treatment and management.
    • Understanding VLM's presentation aids in differentiating it from malignant hepatic lesions.
