| Abstract: | Summary Two patients were scanned 2–5 weeks following onset of subarachnoid haemorrhage. A similar CT appearance was seen in each case. A ring enhancing mass lesion was present within the corpus callosum, suggesting an underlying tumour. However subsequent angiogrphy showed that each case was in fact due to rupture of a pericallosal artery aneurysm. The enhancing membrane of the haematoma gave the false impression of a corpus callosum tumour. |
