Spot sign and live-imaged dramatic intracerebral hematoma expansion

摘要: # {#article-title-2} To the Editor: Garcia Bermejo et al.1 report a patient with deep intracerebral hemorrhage (ICH) and positive spot sign that dramatically expanded from less than 1 mL/min on average in first hour (45 mL/60 min) to an of 4 over 10 minutes between noncontrast CT angiogram scans. We speculate this abrupt expansion resulted pressure gradient caused by sudden decompression hematoma into ventricular space. The did not further expand subsequent hours, suggesting rate rapidly slowed when ventricles filled blood …
