A rare anomaly of the anterior communicating artery complex hidden by a large broad-neck aneurysm and disclosed by three-dimensional rotational angiography.

abstract：BACKGROUND:Schwannomas occur sporadically or in association with neurofibromatosis 2 (NF2), an autosomal dominant disorder, which predisposes to multiple schwannomas, meningiomas and spinal ependymomas, with bilateral vestibular schwannomas as the classic hallmark. As NF2 and sporadic schwannomas differ in some respect...
