Transalar encephaloceles are rare lesions that do not fit the standard classification of basal encephaloceles. Typically, these lesions present in adulthood, with nonspecific symptoms. We report here a case of a patient with Wegener disease in whom a large transalar encephalocele posterior to the sinus was noted when he was preoperative for left maxillary sinus surgery. The encephalocele demonstrated irregular peripheral enhancement along the margin--a very uncommon finding--as well as contrast enhancement of the basal meninges, which can be seen occasionally with Wegener granulomatosis.
经翼脑膨出是一种罕见的病变，不符合基底脑膨出的标准分类。通常，这些病变在成年期出现，症状不具特异性。我们在此报告一例韦格纳病患者，该患者在接受左上颌窦手术术前检查时，发现鼻窦后方有一个巨大的经翼脑膨出。脑膨出沿边缘显示不规则的周边强化，这是一个非常罕见的发现，同时基底脑膜也有强化，这在韦格纳肉芽肿病中偶尔可见。
