Introduction: Pilocytic astrocytoma is a common tumour in paediatric patients. A low-grade glioma, it is most commonly treated by surgery, with various post-surgical side effects. New methods of treatment and follow-up are constantly evolving to offer alternative options to paediatric patients whose nerve structures are developing.
Case presentation: A 9-year-old patient diagnosed with a pilocytic astrocytoma by MRI and histopathological examination underwent a biopsy and evacuation procedure of the cystic component after which the patient’s condition improved significantly. The ‘wait-and-see’ approach using MRI instead of total surgical excision of the tumour was preferred, and the patient had favourable results on control imaging.
Conclusions: Paediatric patients suffering from pilocytic astrocytoma with favourable imaging and histopathological features may consider MRI follow-up instead of surgical excision until the character of the tumour changes or until the brain has reached full development.
