Fig. 5From: A novel MRI feature, the cut green pepper sign, can help differentiate a suprasellar pilocytic astrocytoma from an adamantinomatous craniopharyngiomaA 63-year-old patient with a suprasellar ACP. (A) Axial T2-weighted image demonstrates a cystic-solid mass. (B) Axial postcontrast T1-weighted, (C) coronal postcontrast T1-weighted, and (D) sagittal postcontrast T1-weighted images illustrate ring enhancement with a marked enhancing mural nodule. Unlike the cut green pepper sign, the inner wall of the tumor is smooth, there is no crest, and there is no green pepper seed-like enhancement inside the tumorBack to article page
