Noncontrast CT images show a large region of hypodensity and cytotoxic edema with blurring of the grey-white matter differentiation and gyral hyperdensity due to gyral hemorrhagic transformation and moderate mass effect on adjacent falx with effacement of the right occipital horn. Density of dural sinuses at initial imagings appear normal, that may be contributed to patient anemia (Hb:10 & HCT:29).
