摘要： 对3 例以丘脑病变为影像学特征的脑静脉窦血栓形成患者的临床资料和发病特点进行回顾分析，均存在脑静脉窦血栓形成危险因素（急性脱水、产褥期）；临床主要表现为头痛、恶心呕吐、记忆力减退、偏瘫、昏迷等。MRI检查可见单侧（1 例）或双侧（2 例）丘脑病变，脑血管造影（MRV 和DSA）显示病变部位累及直窦（3 例）、下矢状窦（2 例）、上矢状窦（1 例）和横窦（1 例）。对于呈急性发病的单侧或双侧丘脑病变，尤其是存在脑静脉窦血栓形成危险因素的患者，应首先考虑脑静脉窦血栓形成之可能。

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.
