Figure 1: (a) Plain computed tomography (CT) head of the patient who was noticed to have upper limb monoplegia in the postoperative period, showing the development of a nonhemorrhagic venous infarct. The differentiation between peritumoral edema (a) and infarction may be difficult on CT scans and presence of neurological deficits strongly favors the latter diagnosis (b) plain CT head (same patient) done on postoperative day 4, showing hemorrhagic transformation of the venous infarct
