Extensive subarachnoid hemorrhage distributed throughout perimesencephalic cisterns (predominantly in the chiasmatic cistern), prepontine cistern, both Sylvian fissures, and interhemispheric fissure, with a component of bifrontal parasagittal intraparenchymal hematoma with mild adjacent vasogenic edema. The hemorrhage also extends into the ventricular system (third ventricle and lateral ventricles). Findings consistent with modified Fisher grade IV subarachnoid hemorrhage.

This extension is compatible with an aneurysmal subarachnoid hemorrhage pattern.

Erasure of cerebral sulci, predominantly frontotemporal, in relation to diffuse cerebral edema.

Increased ventricular size for the patient's age.

Additional intracerebral hemorrhage (ICH) was associated with an increased risk of delayed cerebral ischemia (DCI). Furthermore, adding the presence or absence of ICH to the modified Fisher Scale (mFS) improved the identification of patients at the highest risk for the development of DCI. Thus, a simple adjustment of the mFS might help to identify patients at high risk for DCI ²⁾.

The mFS and the modified Graeb score (mGS) have similar prognostic utility. Accounting for IVH volume improved prediction of Delayed cerebral ischemia (DCI) by the mFS ³⁾.
