1例14岁男孩，患有牵牛花盘异常(MGDA)，视觉和神经功能正常，在磁共振血管成像(MRA)上显示明显的颈动脉狭窄，6个月后的随访MRA上这种狭窄消失。光学相干断层扫描和激光偏振扫描显示MGDA患者眼内有正常的视网膜神经纤维层。据报道，MGDA与导致Moya Moya病的不可逆颈动脉狭窄有关。本病例提示轻度MGDA可能与血管痉挛引起的可逆性颈动脉狭窄有关。
A 14-year-old boy with morning glory disc anomaly (MGDA) and normal visual and neurologic function displayed marked carotid artery narrowing on magnetic resonance angiography (MRA), This narrowing disappeared on a follow-up MRA six months later. Optic coherence tomography and scanning laser polarimetry disclosed a normal retinal nerve fiber layer in the eye with MGDA. MGDA has been reported in association with irreversible carotid artery stenosis leading to moya moya disease. This case suggests that mild cases of MGDA may be associated with reversible carotid artery narrowing owing to vasospasm.
