Response by Orito and Morioka to Letter Regarding Article, "Leakage Sign for Primary Intracerebral Hemorrhage: A Novel Predictor of Hematoma Growth".
BACKGROUND AND PURPOSE Recent studies of intracerebral hemorrhage treatments have highlighted the need to identify reliable predictors of hematoma expansion. Several studies have suggested that the spot sign on computed tomographic angiography (CTA) is a sensitive radiological predictor of hematoma expansion in the acute phase. However, the spot sign has low sensitivity for hematoma expansion. ...

Background and Importance: Coronavirus 19 is caused by the SARS-COV-2 virus. The primary target of the virus is the respiratory system, but it can also affect other systems of the body, such as the cardiovascular system and the Central Nervous System )CNS). Case Presentation: In this study, we introduce an 83-year-old man who referred due to reduced level of consciousness and hemiparesis ...

Letter by Murai Regarding Article, “Leakage Sign for Primary Intracerebral Hemorrhage: A Novel Predictor of Hematoma Growth” To the Editor: We read the article by Orito et al on the predictability of contrast extravasation and hematoma expansion through the use of computed tomographic angiography (CTA) phase and delayed phase CT with great interest. Previously, we explored indicators of hematom...
متن کاملPredictive Value of CTA Spot Sign on Hematoma Expansion in Intracerebral Hemorrhage Patients
Hematoma expansion (HE) occurs in approximately one-third of patients with intracerebral hemorrhage and leads to high rates of mortality and morbidity. Currently, contrast extravasation within hematoma, termed the spot sign on computed tomography angiography (CTA), has been identified as a strong independent predictor of early hematoma expansion. Past studies indicate that the spot sign is a dy...
متن کاملSystematic characterization of the computed tomography angiography spot sign in primary intracerebral hemorrhage identifies patients at highest risk for hematoma expansion: the spot sign score.
BACKGROUND AND PURPOSE The presence of active contrast extravasation (the spot sign) on computed tomography (CT) angiography has been recognized as a predictor of hematoma expansion in patients with intracerebral hemorrhage. We aim to systematically characterize the spot sign to identify features that are most predictive of hematoma expansion and construct a spot sign scoring system. METHODS ...
