Focal Nodular Hyperplasia (FNH) is a benign liver lesion, often discovered incidentally during abdominal ultrasound examinations. Characterized by a central stellate scar and normal hepatocytes, it’s a non-cancerous growth that typically requires no treatment. Ultrasound imaging is key for initial detection and monitoring, often presenting as a well-defined mass with variable echogenicity.
Understanding FNH in abdominal ultrasound is crucial for accurate diagnosis, differentiating it from malignant liver tumors. While usually asymptomatic, its distinct appearance on imaging helps clinicians avoid unnecessary interventions. Timely and precise identification via ultrasound supports effective patient management in abdominal imaging.
