Liver and bile duct lesions

Hepatic lesion is usually detected by ultrasound. If it is typical of a cyst, the investigation will end there. If it is typical of a hemangioma, ultrasound monitoring will be sufficient. If it is an indeterminate lesion on ultrasound such as atypical hemangioma in a steatotic liver or solid lesion, or if ultrasound is technically limited, especially if the patient has a primary neoplasm, then a two- or three-phase CT-Scan is indicated. The CT-Scan will allow thecharacterization of the lesion and its pattern of enhancement in arterial and venous phases. It is also useful to search for metastases and for diagnosis of hemangioma, adenoma, focal nodular hyperplasia, hepatoma or in another context, abscesses, post-op biloma, etc.
