Non-contrast cranial CT imaging prior to and post hematoma evacuation. (A) This axial non-contrast CT brain scan shows a sub-acute, right-sided subdural hematoma with mass effect at the time of admission. (B) This axial non-contrast CT brain scan shows increased soft tissue density in the foramen magnum and the lack of hypodense cerebrospinal fluid at the time of admission, marked by the circle. (C) This axial non-contrast CT brain scan shows a sizeable acute right subdural hematoma, with moderately severe mid-line shift, 2 days after emergency craniotomy. (D) This axial non-contrast CT brain scan shows a reduced sub-acute right subdural hematoma, with moderate mid-line shift, 5 days after emergency craniotomy. (E) This axial non-contrast CT brain scan shows a relatively reduced soft tissue density in the foramen magnum with the appearance of some hypodense cerebrospinal fluid, 5 days post emergency craniotomy, marked by the circle. (F) This axial non-contrast CT brain scan shows a lesion on the left cerebral peduncle (marked by the circle), which appears to be responsible for the false localizing sign.

This was later demonstrated by MRI imaging at 1-month follow-up (Figure 1F).

Axial and sagittal MRI imaging at 1-year. (A) This axial non-contrast MRI brain scan shows complete resolution of the right subdural hematoma and no mass effect. (B) This sagittal MRI brain scan shows normal positioning of the cerebellar tonsils and no evidence of herniation into the foramen magnum.

At the 1-year mark, cranial MRI has remained negative for any SIH-related pathologies (Figure 2).
