The intraventricular-spot sign: prevalence, significance, and relation to hematoma expansion and outcomes.

We studied the prediction of spot sign on hematoma expansion and clinical outcomes in the different subtypes of ICH. Our study showed that spot sign is a good predictor in IPH but not IVH. Despite the rarity of IVH; the prevalence of spot sign was higher in IVH than IPH. This might be due to anatomical and physiological variations.
