摘要: We report a case of multiple small, presumably iatrogenic, cortical infarctions detected incidentally on magnetic resonance imaging (MRI) 5 days after preoperative cerebral angiography but not apparent 12 the noncontrast MRI including fast fluid-attenuated inversion recovery (FLAIR) sequence. However, lesions showed marked contrast enhancement with gadolinium postcontrast T1-weighted images. Cortical laminar necrosis was observed 35 initial angiographic study. This shows that fogging effect may prevent detection small in subacute stage even FLAIR sequences. Postcontrast images should be studied to reduce diagnostic errors associated this effect.
