Fibrolamellar hepatocellular carcinoma: Advances, challenges and opportunities in a rare malignancy

Table 1 Main characteristic of fibrolamellar hepatocellular carcinoma in imaging modalities

Modality	Characteristic findings	Diagnostic utility
Computed tomography	Large, lobulated mass with central scar, calcifications	Good for detecting mass, vascular involvement
Magnetic resonance image	T2 hyperintense mass, T1 hypointense, scar hypointense	Better for soft tissue contrast, evaluates central scar
Ultrasound	Hypoechoic, heterogeneous lesion	First-line, limited specificity
PET/CT	May be useful in recurrence or unclear imaging	Not standard, adjunct in certain scenarios

PET: Positron emission tomography; CT: Computed tomography.
