We report a case of congenital left temporal lobe arteriovenous malformation (AVM) detected by cranial ultrasound in utero and confirmed immediately after birth by cranial Doppler ultrasound and cranial MRI. The AVM disappeared on follow-up cranial MRI 4 months later. A small left frontal subdural collection was present on these follow-up MR images, which subsequently resolved by the 7 month MRI study. The cause of the spontaneous thrombosis of the AVM is uncertain. The frontal subdural collection may be secondary to volume loss. This case documents the perinatal presence of AVM. The baby was neurologically intact before, during and after the thrombosis of the AVM.
我们报告一例先天性左颞叶动静脉畸形（AVM），该病例在子宫内通过头颅超声检测到，并在出生后立即通过头颅多普勒超声和头颅MRI得到证实。4个月后的随访头颅MRI显示该AVM消失。这些随访MR图像上出现了一个小的左侧额部硬膜下积液，随后在7个月的MRI检查时积液消失。AVM自发血栓形成的原因尚不确定。额部硬膜下积液可能继发于容积减少。该病例记录了AVM在围产期的存在情况。在AVM血栓形成之前、期间和之后，婴儿的神经功能均正常。
