Concise reasoning: Post-partum cerebral venous (superior sagittal) sinus thrombosis typically presents within days of delivery with headache and seizures, and CT often reveals a hemorrhagic infarct/hematoma in the parasagittal cortex; this pattern fits the 2 × 3 cm parasagittal bleed described, whereas hypertensive hemorrhage is usually deep, eclampsia lacks focal hematoma, and pituitary apoplexy is sellar.
