ABSTRACT

PURPOSE: Intracerebral hemorrhage (ICH) accounts for up to 20% of all strokes, and there is a high rate of associated morbidity and mortality. Computed tomography (CT) findings, such as a spot sign have been shown to be an independent predictor of poor outcome. We have recently encountered a succession of ICH patients who presented with a peculiar imaging finding, which we term the spot on a string sign. This is a rare imaging finding, and interestingly, all these patients presented to our institution over the last few weeks. METHODS: This was a single high-volume center series of patients who presented to our institution between 1 April and 21 May 2020. All patients underwent initial non-contrast CT brain and subsequent CT angiography (CTA). We also present laboratory and clinical data. Our primary measure was the presence of the spot on a string sign on the CTA. We also report the clinical course of these patients. RESULTS: In this study seven large-volume ICH patients with this imaging sign were identified, with a median age of 48 years (range 30-68 years). All had tested negative for coronavirus disease 19 (COVID-19). CONCLUSION: We have described an unusual imaging finding in a cohort of younger patients with large-volume ICH, all of whom presented in a 2-month period to a high-volume neurovascular unit. The cause of these ICH presentations and associated imaging findings are unclear, but we encourage other clinicians to be aware of and vigilant for this rare phenomenon, especially in younger patients with such a bleeding pattern.
