Abstract
Background: We describe a rarte case of an extracranially located schwannoma of the hypoglossal nerve (CN XII). Case report with review of literature with emphasis on a possible iatrogenic lesion of the hypoglossal nerve.
Initial intervention consisted of a biopsy of the tumour in a neurosurgical department, which resulted in a iatrogenic transsection of the still-functional CN XII. The tumour was completely excised at subsequent surgery.
Conslusion: In cases of unclear bulges of the neck, an MRI should be performed before scheduling surgical intervention, in order to prevent possible iatrogenic injury.
