From: Amide proton transfer imaging-arterial spin labeling mismatch: a new imaging biomarker for pilocytic astrocytoma

Figure 2

A well-defined T2 hyperintense (B) large solid non cystic mass lesion seen involving the left side pons, left cerebellar hemisphere. Lesion showed diffuse hypoperfusion in ASL (A) and diffuse high values in Amide Proton Transfer Imaging (C). Amide Proton Transfer-Arterial spinal labeling (APT-ASL) mismatch seen. Lesion appears T2 FLAIR (D) hyperintense, and shows aggressive heterogenous enhancement (E), with no significant diffusion restriction (F, high apparent diffusion coefficient-ADC). Conventional imaging differential diagnosis were ependymoma, pilocytic astrocytoma. This is a histologically proven Grade 1 Pilocytic Astrocytoma.
