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

Figure 3

A T2 hyperintense (B) solid expansile mass lesion seen involving the medulla. Lesion showed diffuse hypoperfusion in ASL (A) and diffuse high values (C) in Amide Proton Transfer Imaging. Amide Proton Transfer-Arterial spinal labeling (APT-ASL) mismatch seen. Lesion appears T2 FLAIR (D) hyperintense, and shows heterogenous enhancement (E), with no significant diffusion restriction (F). Imaging differentials based upon on conventional sequences were astrocytoma, ependymoma. But the final histological diagnosis was Grade 1 Pilocytic Astrocytoma.
