摘要：

Purpose: Cerebral venous thrombosis (CVT) has various clinical presentations and has a median onset delay of 7 days. So it is important to find more identifiable early imaging manifestations for CVT. Method: This was a retrospective study. Patients with CVT (CVT group, n = 26) diagnosed by conventional imaging techniques (magnetic resonance imaging and/or digital subtraction angiogram) and patients with symptomatic intracranial atherosclerosis (control group, n = 30) were included. Magnetic resonance black-blood thrombus imaging (MRBTI) technique had been performed in both groups. The CVT group was divided into 3 groups based on the duration of clinical onset: ≤7 days (group 1), between 7 and 30 days (group 2), and >30 days (group 3). Pathological pachymeningeal enhancement and its characteristics were analyzed between the CVT group and the control group. Results: Pathological pachymeningeal enhancement was found in 14 CVT patients (54 %) and none in control group (P value = 0.000). The bilateral pathological pachymeningeal enhancement was involved in 10 CVT patients, 6 patients were asymmetric, and 4 patients had ipsilateral enhancement. Asymmetric pathological pachymeningeal enhancement was 71 % and predominantly located on the thrombosed sinus side. Strong enhancement was found in the venous sinus wall beside the thrombus. Pathological pachymeningeal enhancement percentages of three subgroups were 75 % in group 1, 55 % in group 2, and 29 % in group 3 and had no statistical differences (p value = 0.198). Conclusions: Current findings suggest asymmetrical pathological pachymeningeal enhancement was associated was CVT and may be a new imaging feature for CVT. © 2021
