Overview

Overview

CT scan may be helpful in the workup of hyperosmolar hyperglycemic state when a patient presents with an altered state of consciousness or with focal neurological signs and symptoms to rule out stroke. CT scan can also help in the diagnosis of cerebral edema which can occur as a complication of treatment of hyperosmolar hyperglycemic state.

  • CT scan may also aid in the diagnosis of cerebral edema which can occur as a complication of treatment of hyperosmolar hyperglycemic state.[1]
  • The following findings can be seen in cerebral edema 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
