Diffuse sulcal narrowing, representing a change from the prior exam, and loss of gray-white differentiation, most likely due to diffuse cerebral edema.
Contrast enhancement of the vessels consistent with residual contrast from prior exams as the current exam was performed without contrast.
Case Discussion
This case illustrates a rare occurrence of pneumocephalus during dialysis with a hemodialysis catheter, with 24-hour follow-up CT showing resolved intracranial gas but interval development of diffuse cerebral edema.
