Vascular and Nonvascular Mimics of the CT Agniography "Spot Sign" in Patients With Secondary Intracerebral Hemorrhage Stroke 39:1177-1183, Gazzola,S.,et al, 2008 See this aricle in Pubmed Article Abstract This study describes mimics of the CTA Spot Sign and classifies them as vascular (microAVM, aneurysm, Moya Moya) or nonvascular (tumor and choroids plexus calcification). Evaluation of the noncontrast CT together with the CTA source images is an essential part of the evaluation for the Spot Sign. Vessels entering the hematoma from the periphery are indicative of an underlying vascular lesion. Our findings suggest that the Spot Sign may be rate in secondary ICH and most specific for PTCH.
