Fig. 3From: A novel MRI feature, the cut green pepper sign, can help differentiate a suprasellar pilocytic astrocytoma from an adamantinomatous craniopharyngiomaA 23-year-old patient with a suprasellar PA. (A) Axial CT image shows a cystic-solid heterogeneous suprasellar mass. (B) Axial T2-weighted image demonstrates predominant hyperintensity of the mass, with slight hypointensity of the nodule. (C) Axial T1-weighted image reveals hypointensity of the mass, with slight hyperintensity of the nodule. (D) Axial postcontrast T1-weighted image shows irregular rim enhancement with a mural nodule and multiple crests connecting the indentations on the surface, which is similar to the appearance of the flesh of a cut green pepperBack to article page
