深部脳静脈血栓症の3症例

Abstract

Cerebral venous thrombosis is a rare and uncommon type of stroke, and the deep venous system is affected in approximately 10% of cases of cerebral venous thrombosis. The clinical presentation of deep cerebral venous thrombosis is variable and nonspecific, and hence, it is difficult to diagnose this condition. In this report, we describe three cases of deep cerebral venous thrombosis. All the cases presented with mild decreased consciousness, and two cases also experienced quadriparesis. Magnetic resonance (MR) images demonstrated vasogenic edema in the thalamus/thalami, and T2* -weighted MR images indicated a thrombus in the deep venous system in all the cases. Hence, T2* -weighted MR images and magnetic resonance venography is useful for the early diagnosis of deep cerebral venous thrombosis, which can be followed by prompt treatment.
