title: Ectopic recurrence of craniopharyngioma along the surgical route: case report and literature review.
abstract: We present a 22-year-old woman with an ectopic recurrence of a craniopharyngioma. The patient presented first with a visual field deficit, and a craniopharyngioma was removed via an interhemispheric transcallosal approach. Magnetic resonance imaging (MRI) performed at 1 month, and then at 1 year after surgery showed complete removal of the lesion. However, at 4 years, MRI showed the presence of a small tumor in the right medial frontal lobe attached to the falx and along the previous surgical route. We present possible explanations for the ectopic recurrence and literature review.
