Imaging after conivaptan administration. Comparative images at the level of thalamus pre (A) and post (B) conivaptan administration shows significant reduction in vasogenic edema (red arrows) with normal density appearing tissue seen in the ventral aspect of right thalamus following conivaptan administration (thick blue arrow). Moreover, comparative images at the level of mid brain pre (C) and post (D) conivaptan administration clearly demonstrate significantly reduced hypodensity (red arrows), especially adjacent to the quadrigeminal cistern. The normal density appearing tissue emerges following conivaptan administration (blue arrow heads).
