Excerpt

Intracerebral hemorrhage (ICH) persists as a significant cause of morbidity and mortality worldwide. Determining prognostic factors is primordial to achieve a prompt management. The spot sign was first reported in 2007 as a focal area of contrast enhancement within a hematoma in computed tomography angiography (CTA) [1]. Over time, studies have shown that it can be associated with hematoma expansion (HE) and unfavorable outcomes [2]. This finding is thought to represent active bleeding; however, it is sometimes confused with mimics of the spot sign. …
