The “White Cerebellum Sign” after cardiac arrest

The white cerebellum sign, or reversal sign, is a rare radiological image in computed tomography of the head characterized by a hypodense image of the cerebral hemispheres with loss of white and gray matter differentiation and a relatively hyperdense image of infratentorial structures. It occurs in patients with severe, often irreversible, cerebral hypoxia. In the presented case of an 82-year-old patient with numerous comorbidities, the sign appeared about a week after successful cardiac arrest resuscitation. Despite intensive therapeutic management, the patient’s condition could not be improved, and palliative care was initiated.
