Think again	2018	1	.pdf	application/pdf	568	33	48	Marked cerebral oedema may develop in patients with hypoxic encephalopathy, severe head trauma, meningitis, postradia- tion therapy, and hypervolemia.1,2 Several studies have reported that cranial CT of such patients sometimes reveals increased attenuation along the basal cisterna or corti- cal sulci, which mimics SAH.1-3 The key to differentiating true and pseu- do-SAH is identifying the presence of severe cerebral oedema in the absence of a large amount of subarachnoid blood or a substantial parenchymal haematoma on a cranial CT scan. Cranial CT of pseudo-SAH will show the marked effacement of sulci and basal cisterns, slit-like ventricles, and poor grey-white matter differentiation.1,2 Furthermore, the distribution of blood along the fissure and sulci exhibits irregular hyperdensity in true SAH, whereas it dis- plays a smoother line in pseudo-SAH.	cache/ecj-6681.pdf	txt/ecj-6681.txt
