INTRODUCTION: Olfactory groove schwannomas (OGSs) are extremely rare tumours, particularly in the paediatric population. CASE REPORT: A 13-year-old girl presented with two epileptic seizures, papilloedema and incomplete binasal quadrantanopia. Computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated a large heterogeneously enhancing tumour of the anterior skull base with a prominent dorsal pseudocyst. Interestingly, the pseudocyst embraced the right ICA bifurcation and displaced the optic tracts, optic chiasm and optic nerves and the ipsilateral basal ganglia. The patient underwent surgery via the frontolateral approach, and the tumour was completely removed. The pseudocyst was opened, and its wall was partially resected. It subsequently resolved completely. Histopathological examination yielded the rare diagnosis of schwannoma of the anterior skull base. CONCLUSION: Although extremely rare, olfactory groove schwannomas can be seen in paediatric patients. Our patient is the youngest ever reported with this histopathological diagnosis along with the formation of a large pseudocyst.
