Pilocytic astrocytoma mimicking craniopharyngioma: a case series
Although they are one of the most common brain tumours in childhood, piiocytic astrocytomas are rare in adulthood. We report a series of three piiocytic astrocytomas presenting as an intra/suprasellar mass in the fourth to sixth decades of life. All three radiologically mimicked the appearance of a craniopharyngioma, thus representing a potential radiological and diagnostic pitfall. In this series all three patients underwent successful operative management and have remained well throughout follow-up. The majority of information concerning piiocytic astrocytomas is derived from paediatric populations and so only limited and often conflicting data exist for piiocytic astrocytomas developing in adulthood. Decisions regarding treatment of piiocytic astrocytomas in adults must be made on a multidisciplinary, case-by-case basis.
