Non-contrast Computed Tomography Imaging Findings and Diagnosis Of Cerebral Venous Sinus Thrombosis

Abstract

Objective: To ascertain the frequency of abnormal imaging in patients with symptomatic cerebral venous
sinus thrombosis.
Method: This was a prospective, Cross-Sectional study done in the Department of Neurology, Mayo
hospital, Lahore. The study was conducted after approval from the ethical review board. The study duration
was 5 years. Patients with clinically suspected CVST from june 2016 to June 2021 were enrolled. A total of
177 patients with symptoms and signs suggestive of CVST on the initial evaluation, irrespective of age and
gender, were involved in the study. Diagnosis of CVST was made clinically and on CT brain plain and was
later confirmed with MRI Brain plain & contrast and MRV.
Results: Of the study sample of 177 patients, 36 (20.34%) patients were male and 141 (79.66%) were
females. The mean duration of symptoms was 2.53±1.27 weeks. Cord sign was observed in 14(7.9%)
patients, hemorrhagic infarct in 35(19.8%), and infarct with edema reported in 37(20.90%) patients.
Conclusion: CT brain plain is non-invasive and is the most sensitive and best modality in detecting cerebral
venous sinus thrombosis. In our study infarct with edema (20.90%) was the most observed abnormality
followed by hemorrhagic infarct (19.8%). We delineate in this study that non-enhanced CT brain (NECT) can
be used as a first-line investigation in suspected cases of CVST.
