case_images: Imaging with T2WI sequence on 1a (axial through internal capsule/corona radiata), 1b (axial through pons/cerebellum), and 1c (sagittal) demonstrating diffuse hypodensity of the left internal capsule and left corona radiata.

case_images: Coupled with the radiology data ( Figures 1 ,  2 ), these results were only somewhat suggestive of an infiltrating astroglia neoplasm.

case_images: Hematoxylin and eosin (H&E) staining of tumor biopsy. Distinct features of atypical glial infiltrate are not definitively demonstrated and it is not feasible to establish a morphologic diagnosis of glioblastoma given the pontine location, as a biopsy sufficient to establish such a diagnosis would likely kill the patient.

case_images: Upon reviewing the second set of permanent tissue samples, pathology identified a somewhat atypical glial infiltrate ( Figure 3 ) with the majority of the astroglia nuclei labeling Ki-67 ( Figure 4 ).
