Semantic features for image analysis ((a–f): patients with CPA; (g–h): patients with RCC): (a) fluid-fluid level (short arrow) and wall thickness nonuniformity (long arrow) (sagittal T1 image); (b) a hypointense rim on T2WI (coronal T2 image); (c) heterogeneous of cystic portion (short arrow) and beyond the lateral margin of the cavernous ICA (long arrow) (coronal T2 image); (d) off-midline location (coronal T1 image); (e) sellar floor depression (short arrow) and intracapsular septation (long arrow) (sagittal postcontrast T1 image); (f) ill-defined lesion boundary (coronal postcontrast T1 image); (g) intracystic nodule (coronal T1 image); (h) intracystic nodule (coronal postcontrast T1 image).
