Abstract

Neurofibromatosis type 1 (NF-1) has a variety of localized or systemic manifestations. Among them, Cerebrovascular dysplasia can be very rare finding of neurofibromatosis which can be very rarely seen. Here we report a case of 17-year-old boy representing bilateral giant fusiform aneurysms of extracranial internal carotid arteries and intracranial aneurysms of left middle cerebral artery. He showed no related symptoms at all, but screening for vascular lesions and close monitoring is warranted in NF-1 patients considering that it can be symptomatic unexpectedly.

  Fig. 1 A. T2-weighted image of the patient's brain MRI shows porencephalic change of left cerebral hemisphere shows some cavitation suspiciously communicating with left lateral ventricle.B. Angiography of the right ICA reveals large fusiform aneurysm arising from proximal ICA. The continuous draining artery shows marked tortuous dilation. The aneurysmal filling is not complete enough for the precise deliniation of whole contour of aneurysm.C. Angiography of the left ICA reveals another giant fusiform aneurysm arising from the similar location to right side.D. Intracranial view of left ICA angiography shows two more intracranial fusiform aneurysms (arrows) arising from proximal M1 segment and MCA bifurcation.
