Discrepancies between postmortem non-neuropathological findings and clinical diagnoses, and discrepancies between postmortem neuropathological findings and the last premortem CT scan

Discrepancy	Postmortem non-neuropathological findings Number (N)=534
Class I discrepancy	8 (1.5%) malignancies 68 cases of (12.7%) thromboembolic events: in vivo non-diagnosed thrombosis in the femoral vein or in the periprostatic and periuterine venous plexus, embolus in the lung—without any antithrombotic therapy 36 cases of (6.7%) in vivo non-diagnosed pneumonia, without any antibiotic therapy
Class II discrepancy	12 cases of (2.3%) thromboembolic events: in vivo non-diagnosed thrombosis in the femoral vein or in the periprostatic and periuterine venous plexus, embolus in the lung—with prophylactic antithrombotic therapy 37 cases of (6.9%) in vivo non-diagnosed pneumonia, but prophylactic antibiotic therapy
Class III discrepancy	169 (31.6%) benign findings (cysts, myoma, etc)
	Postmortem neuropathological findings in patients with ischaemia Number (N)=189
Class I discrepancy	66 (34.9%) ischaemic lesions on the premortem CT scan, but haemorrhagic transformation of an infarct on brain autopsy
