case_images: Noncontrast head computed tomography (CT) scan. (a-b) Scan obtained on admission demonstrating subarachnoid hemorrhage in the suprasellar cistern with intraventricular extension; (c-d) Significant increase in the size of intraventricular hemorrhage with a midline shift of 10 mm

case_images: FIG1
case_images: A noncontrast head computed tomography (CT) scan was done, which showed a large intraventricular hemorrhage in the right lateral ventricle and suprasellar cistern, dilatation of ventricular and basal systems, and effacement of sulci suggestive of SAH (Figures 1a, 1b). CT scan that revealed further expansion of the intraventricular hemorrhage involving the right temporal lobe, dilation of the ventricular system, and a midline shift of 10 mm (Figures 1c, 1d). Consequently, the patient underwent a life-saving craniotomy for hematoma evacuation and external ventricular drain insertion (Figure 2).

case_images: Histopathology of cavernous malformation. Compact vessels of variable caliber and degree of wall collagenization with no significant intervening brain parenchyma and blood suggestive of cavernoma; (a) Masson's trichrome stain x20; (b) H&E stain x20
