A 38-year-old female presented with a 4-day history of acute onset of headache, fever of 40°C, and generalized fatigue at a peripheral hospital. The patient presented no neurological deficits, especially no signs of meningism, and the remaining examination was normal. The CRP was increased (192 mg/l, normal <5 mg/l). Creatinine (1.03 mg/dl) and blood urea nitrogen (38.0 mg/dl) were normal. The cranial CT scanning excluded subarachnoid hemorrhage. A cranial MRI excluded cerebral venous sinus thrombosis, but showed a hyperintense lesion in the splenium of the corpus callosum (Fig. 1a–c). The patient was transferred to the university hospital. A lumbar puncture could not be performed at that time, due to thrombocytopenia and abnormal coagulation (platelets 51 × 10 3/μl and the partial thromboplastin (PTT) time was prolonged to 44.1 s). The general condition of health was reduced, accompanied by tachycardia and dyspnea, but vigilance was not affected and neurological examination...
