Clinical characteristics of cerebral venous sinus thrombosis with thalamic lesions in imaging examination

Abstract

A retrospective study was performed on 3 patients with cerebral venous sinus thrombosis (CVST) who were characterized with thalamic lesions in MRI examination. Among 3 CVST cases, one were male, and 2 was female, aged from 17 to 68. All cases had risk factors of CVST such as acute dehydration and puerperium. The main clinical symptoms included headache, nausea and vomiting, hypomnesis, hemiplegia and coma. MRI examination showed one case with unilateral thalamic lesions and 2 cases with bilateral thalamic lesions. Magnetic resonance venography (MRV) and DSA revealed straight sinus lesions in 3 cases, inferior sagittal sinus lesions in 2 cases, superior sagittal sinus lesion in one case, and transverse sinus lesion in one case, respectively. The patients with unilateral or bilateral thalamic lesions, especially those who had risk factors of CVST, should be diagnosed correctly and timely. doi: 10.3969/j.issn.1672-6731.2014.08.014
