Predictive Value of CTA Spot Sign on Hematoma Expansion in Intracerebral Hemorrhage Patients

Figure 3

This graphic represents 8 other causes for spot sign on CTA, vascular mimickers (fibrin globules, micro-arteriovenous malformation (micro-AVM), aneurysm, microvascular aneurysm, Moyamoya, and pial arteriovenous fistula) and nonvascular mimickers (tumor and choroid plexus calcification). This suggests that not all positive spot signs represent ongoing bleeding and clinical judgment and other diagnostic tools should be utilized.
