Magnetic resonance imaging of the patient’s brain without contrast from February 9, 2015. A large focus of abnormal restricted diffusion is demonstrated in the brainstem (red arrow), consistent with recent infarction. This primarily affects the cranial aspect of the pons, possibly extending into the midbrain. This is a bilateral finding, with more extensive involvement on the left. This is concordant with findings from computed tomography of the patient’s head on February 7, 2015. Mild associated mass effect and swelling are present at this time
