182.A Case Review Series : Case2 AVM(动静脉畸形)

Case2

Arteriovenous Malformation

Clinical

About half present with headache secondary to hemorrhage

More than half have an associated aneurysm

~1/4 have associated seizures

Patients may have progressive neurologic dysfunction secondary to related hypoperfusion or microhemorrhage

病例回顾2---动静脉畸形AVM】 临床表现：半数患者在大量出血后继发头痛。超过半数患者伴有动脉瘤。约1/4患者有癫痫发作。由于低灌注和微出血，患者可能会产生进行性的神经功能障碍。

Imaging

“Bag of worms,” tangle of vessels

MRI: “Honeycomb” of flow voids, may have blooming on GRE if hemorrhage, nidus enhances, enlarged feeding artery/-ies and early draining vein(s)

影像表现：“一带蠕虫”征：扭曲的血管团。MRI：“蜂窝状”血管流空影，若有出血，在GRE上表现为开花正。病灶有强化，供血动脉和早期引流静脉扩张。

DDx: Other vascular malformation such as dural AV fistula or cavernoma, vascular neoplasm/metastasis, meningioma

鉴别诊断：其他血管畸形比如硬脑膜动静脉瘘、海绵状血管畸形、血管肿瘤、血管转移瘤、脑膜瘤。

Tx:

Embolization

Stereotactic radiation therapy

Surgical resection

治疗：栓塞、立体定位放疗、手术切除。
