Question

Enumerate the various focal benign hepatic lesions that may be seen in adults.

Hint:

Hemangiomas are the most common benign hepatic lesions and are often discovered incidentally during imaging studies.

Answer 1

Focal benign hepatic lesions are commonly found in adults and can vary in their appearance and clinical significance. The most common focal benign hepatic lesions include:
1. Hemangioma: A vascular lesion, often asymptomatic, seen as a well-defined lesion on imaging.
2. Focal Nodular Hyperplasia (FNH): A benign tumor characterized by a central scar, often with a hypervascular appearance on imaging.
3. Hepatic Adenoma: A benign tumor of hepatocytes, often associated with oral contraceptive use or anabolic steroid use.
4. Simple Cyst: A common and benign lesion, typically fluid-filled and without solid components.
5. Regenerative Nodule: Often found in cirrhotic livers, these nodules are typically surrounded by fibrous tissue and can appear as focal masses.
6. Lipoma: A benign tumor composed of adipose tissue, typically asymptomatic.
These lesions are typically identified using imaging techniques like ultrasound, CT, and MRI, and they often do not require surgical intervention unless symptomatic or concerning for malignancy.
