Introduction: Pilocytic astrocytoma, represents 5-6% of glial tumours, classified as grade I by the World Health Organisation. It tends to grow slowly and often contains cysts. Case report: We report the case of a young girl aged 6 years and 5 months, presenting a huge heterogeneous intra and supra sellar mass (87*65*44 mm) suggesting a craniopharyngioma. Anatomopathological and immunohistochemical examination revealed a tumoral proliferation compatible with a grade 1 pilocytic astrocytoma. Adjuvant chemotherapy and radiotherapy were indicated. Discussion & Conclusion: The diagnosis of pilocytic astrocytoma is suggested after magnetic resonance imaging which specifies the topography, size, infiltrative or expansive nature of the lesions. Howerver the sellar/suprasellar location of the pilocytic astrocytoma contribute significantly to the diagnostic difficulty. The histological examination allows the diagnosis to be confirmed after biopsy or resection of the tumour and to consider the strategy for further treatment. Management of sellar and suprasellar pilocytic astrocytoma remains challenging and requires a multidisciplinary approach.
