OBJECTIVE: The objective was to describe a rare case of a trigeminal schwannoma in a child and the surgical procedure performed for therapy.
PATIENT AND METHODS: A 6-year-old girl presented with tiredness, dysarthric speech and cerebellar symptoms. Imaging studies revealed a unilateral dumbbell-shaped tumour, extending into both the middle and posterior fossa, centred over Meckel's cave. One-stage surgery was performed by pterional craniotomy. The tumour was first debulked in the middle fossa, then peeled from the wall of the cavernous sinus, followed by extirpation of the tumour from the posterior fossa. The tumour extended to the caudal cranial nerves and was completely removed. Trigeminal fascicles were distributed throughout the tumour. Histopathological examination revealed a schwannoma.
CONCLUSION: Trigeminal schwannoma is a tumour that occurs rarely in childhood. Although several, often multistaged surgical strategies have been reported in the literature, this tumour was eradicated by a one-stage pterional approach.
