Clear cell meningiomas (CCMs) account for only approximately 0.2% of all meningiomas and are classified as grade II tumours by the World Health Organisation. Most of the previously described intracranial CCMs are single tumour entities. Multiple intracranial CCMs are extremely rare, and due to their low incidence, information on multiple CCM remains limited; hence, researchers and practitioners also have a limited understanding of its aetiology, clinical manifestations, and treatment options. Herein, we report a case of sporadic multiple intracranial CCM in a child that presented with a 3-month history of gait instability and mild dysphagia. Brain magnetic resonance imaging showed one lesion in the right frontoparietal lobe and another giant lesion on the ventral side of the brainstem, extending to the middle fossa. The lesions were completely resected in two stages. Postoperative histopathological examination confirmed CCM. The patient was followed up for 2 years without recurrence. To the best of our knowledge this is the first reported case of paediatric sporadic multiple intracranial CCM. In addition, we reviewed the relevant literature to discuss the pathogenesis, imaging findings, and treatment methods of this rare disease.
