Diabetic ketoacidosis CT

Overview

Diabetic ketoacidosis (DKA) is associated with cerebral edema which can be visualized on CT scan of the head.

Key CT Findings for Diabetic Ketoacidosis

Diabetic ketoacidosis (DKA) is associated with vasogenic cerebral edema due to increased osmolality of blood secondary to hyperglycemia, which can be visualized on CT scan of the head.^[1]

The following findings can be seen on CT scan:^[2]^[3]
- Diffuse effacement of the sulci and lateral ventricles
- Hypoattenuation of the brain parenchyma

Axial noncontrast CT scan of the head reveals diffuse effacement of the sulci and lateral ventricles and hypoattenuation of the brain parenchyma. Note also the falx appears hyperattenuating (yellow arrows), source: radiologypics.com
