Aetiology
Malignant neoplasm metastasis in intrahepatic bile duct is caused by the spread of cancer cells from a primary tumor to the intrahepatic bile duct. This type of metastasis is most commonly seen in cancers of the pancreas, colon, stomach, and breast.
Diagnosis
Diagnosis of malignant neoplasm metastasis in intrahepatic bile duct is typically done through imaging tests such as computed tomography (CT) scans, positron emission tomography (PET) scans, and magnetic resonance imaging (MRI) scans. Biopsy may also be necessary to confirm the diagnosis.
Differential diagnosis
Differential diagnosis of malignant neoplasm metastasis in intrahepatic bile duct includes both benign and malignant conditions such as primary sclerosing cholangitis, primary biliary cirrhosis, and primary bile duct cancer.
Treatment
Treatment of malignant neoplasm metastasis in intrahepatic bile duct depends on the type and stage of the cancer. This may include chemotherapy, radiation therapy, or surgery.
Prognosis
Prognosis for malignant neoplasm metastasis in intrahepatic bile duct is generally poor, as the cancer is often advanced by the time it is diagnosed. The prognosis also depends on the type and stage of the cancer, as well as the patient’s overall health.
