Representative cases of fractal parameters in grade 2 meningiomas according to TERTp mutation status.
(a) Images of a 55-year-old female with TERTp wildtype grade 2 meningioma reveals an enhancing tumor in the right cerebellopontine angle on postcontrast T1-weighted image with a major axis of 2.9 cm. The 3D FD and 3D lacunarity were 1.52 and 5.39, respectively. (b) Images of an 80-year-old male with TERTp mutant grade 2 meningioma reveals an enhancing tumor in the left parietal convexity on T1C with a major axis of 5.3 cm. The 3D FD and 3D lacunarity were 1.91 and 6.53, respectively. FD = Fractal dimension, TERTp = telomerase reverse transcriptase promoter, T1C = Postcontrast T1 weighted image.
