Figure 2 Magnetic resonance imaging images. A: Coronal balanced fast field echo (B-FFE) image; B: Coronal T1-weighted image (T1WI) after 150-s gadolinium enhancement; C: Axial image, including T2-weighted imaging (T2WI); D: Diffusion-weighted imaging (DWI); E: Apparent diffusion coefficient (ADC); F: T1WI; G: After 7-min gadolinium enhancement, the lesions showed a high signal on B-FFE, a low signal on T1WI, and no definitive enhancement (circled areas). In the lesions, a strip-shaped flow void vascular signal (black short arrow in Figure 2C) can be seen on T2WI. Multiple irregular strip-like obvious enhancement foci with irregular shapes are shown (white arrowhead in Figure 2B). Some areas of high signal on DWI and low signal on ADC and B-FFE (triangular areas) showing progressive and heterogeneous enhancement with gadolinium contrast enhancement. The mass resembled different meteorites in the various sequences.
