A 55-year-old man with a history of renal transplant on long-term immunosuppressive therapy presents with a 3-month history of intermittent right upper quadrant pain and unintentional weight loss.

A 68-year-old male with known Hepatitis B related cirrhosis and a history of alcohol excess presents for routine surveillance. His alpha-fetoprotein (AFP) level, which has been stable at 15 ng/mL for the past two years, is now noted to be 185 ng/mL. A screening ultrasound performed three months prior was reported as showing diffuse parenchymal changes consistent with cirrhosis but no focal lesions. Due to the elevated AFP, a repeat ultrasound was performed, which identified a 2.5 cm nodule in segment VIII. To further characterise this lesion, a contrast-enhanced ultrasound (CEUS) was performed, and the images provided are representative findings from this study. The patient has well-compensated cirrhosis (Child-Pugh A) and no significant comorbidities. His liver function tests are within normal limits except for a slightly elevated GGT. Given the clinical context and the findings demonstrated in the provided images, what is the most appropriate next step in the management of this patient?
