Web6 mei 2024 · Hyperdensity on nonenhanced CT may provide evidence for the diagnosis of BDA. However, features such as hypointensity on the HBP (Fig. 7 c), hyperintensity on T2-weighted imaging (Fig. 7 d), and cystic change all resemble HCCs. Overall, the diagnosis of BDA is dependent on the pathological examination. Fig. 7 Bile duct adenoma (BDA). Websignal hyperintensity in the central pons (arrows). Axial T1-weighted image (C) shows a hypointense lesion with-out contrast enhancement in the central pons (arrow). High signal intensity on diffusion-weighted imaging (DWI) (D) and low signal on apparent diffusion coefficient (ADC) map (E) are indicative of diffusion restriction.
