SPOT” AND “SATELLITE” SIGNS IN PATIENTS WITH PRIMARY INTRACEREBRAL HEMORRHAGE: IMAGING CHARACTERISTICS AND ASSOCIATION WITH HEMATOMA EXPANSION
Main Article Content
Abstract
Objective: To describe the characteristics of the “spot sign” and “satellite sign” in patients with primary intracerebral hemorrhage (ICH) treated at the Stroke Department of Military Hospital 103. Subjects and methods: A cross-sectional descriptive study was conducted on 116 patients with primary ICH who underwent CTA within 6 hours of symptom onset. The presence of the “spot sign”, “satellite sign”, and Spot Sign Score (SSS) features were evaluated and compared between HE and Non-HE groups. Results: The spot sign was observed in 39.66% of cases, with significantly higher frequency in the HE group (68.75%) compared to the Non-HE group (28.57%), p < 0.001. The satellite sign appeared in 18.10% of patients, also more frequent in the HE group (34.38% vs. 11.90%; p = 0.005). Co-occurrence of both signs was three times higher in the HE group (25.00% vs. 8.33%; p = 0.017). Regarding the SSS, two significant factors were identified: Maximum axial dimension of the spot ≥ 5 mm (86.36% in HE vs. 33.33%; p < 0.001) and SSS ≥ 2 (86.36% vs. 45.83%; p = 0.015). Conclusion: The “spot sign”, “satellite sign”, and higher SSS are strong imaging predictors of hematoma expansion in primary ICH. Their combination enhances predictive accuracy and supports clinical decision-making.
