Summary
Hepatobiliary fascioliasis, a rare liver and bile duct disease, presents with distinct imaging findings. Early diagnosis using imaging and clinical signs is crucial, especially in endemic regions.
Area of Science:
- Medical Imaging
- Parasitology
- Hepatology
Background:
- Hepatobiliary fascioliasis is a rare parasitic infection affecting the liver and bile ducts.
- Clinical presentation can be non-specific, making imaging essential for diagnosis.
Purpose of the Study:
- To detail the imaging characteristics of hepatobiliary fascioliasis.
- To identify and describe a novel imaging finding associated with the disease.
Main Methods:
- Retrospective analysis of five patients diagnosed with hepatobiliary fascioliasis.
- Utilized ultrasonography (US), computed tomography (CT), magnetic resonance imaging (MRI), magnetic resonance cholangiopancreatography (MRCP), and endoscopic retrograde cholangiopancreatography (ERCP).
- Diagnosis confirmed via serology and parasitology.
Main Results:
- Common findings included abdominal pain, eosinophilia, and abnormal liver function tests.
- US revealed hypoechoic nodules/parenchymal heterogeneity; CT showed linear/nodular hypodense lesions.
- A novel finding of hyperdense material in dilated bile ducts was observed; parasites were removed via ERCP in two patients.
Conclusions:
- Hepatobiliary fascioliasis exhibits characteristic imaging findings in the liver and bile ducts.
- Integrating imaging findings with clinical presentation aids diagnosis, particularly in endemic areas.
- Medical treatment with triclabendazole was effective in all cases.

01:27Liver Histology
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.

01:17Gross Anatomy of the Liver
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is covered...
