[Spontaneous intravascular rupture of a giant neuroepithelial cyst]

We report the case of a woman presenting with a gait disorder. Magnetic resonance the brain showed a large parieto-neuroepithelial cyst. Surgery was ruled out and a new image taken nearly two years later showed the cyst cavity had collapsed spontaneously. The benign course of this type of lesion and the possibility of spontaneous recurrence suggest that a wait-and-see attitude can be chosen over surgery in patients with few clinical manifestations.
