Transalar encephalocele associated with Wegener granulomatosis and meningeal enhancement: case report.
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.
