ABSTRACT
OBJECTIVE:
Intracerebral hemorrhages (ICHs) are common in patients with cerebral venous thrombosis (CVT). We examined whether small juxtacortical hemorrhages (JCHs) are characteristic for CVT and studied their radiological and pathological properties.METHODS:
We identified all patients with CVT and an ICH at baseline admitted between 2000 and 2011 (prospectively from July 2006). JCH was defined as a hemorrhage (diameter < 20mm) located in the white matter just below the cortex. To determine the specificity of JCHs for CVT, we examined the frequency of JCHs in a control group of patients of similar age with an ICH not related to CVT.RESULTS:
Of 114 patients with CVT, 53 had an ICH. JCHs were present in 14 of the 53 (26%). The remaining 39 had other kinds of hemorrhages. Papilledema was more common among patients with a JCH compared to patients with other types of ICHs (44% vs 9%, p = 0.01). All patients with a JCH except 1 had thrombosis of the superior sagittal sinus, compared to 49% of patients with CVT and other kinds of hemorrhages (p = 0.004). Reanalysis of all imaging data and histopathologic analysis in 1 patient showed that JCHs are located near the U-fibers and that they follow the curvature of the cortex. Among 196 control patients (spontaneous ICH, not caused by CVT), only 3 patients had a JCH. One of these 3 appeared on re-examination of all imaging results to have had CVT.INTERPRETATION:
Small nontraumatic JCHs are a characteristic feature of CVT and are rarely encountered in other conditions.
