Publication types: Journal ArticlePublication Status: ppublish. pdf type: review
Background: Astrocytomas are the most common brain tumours, accounting for 28 - 50% of all primary CNS tumours. Diagnosis of CNS tumours remains difficult because the varied and nonspecific presentations of CNS tumours in childhood. Objectives/method: The clinical presentations of CNS astrocytomas vary with their sites of location; therefore, a period of uncertainty often precedes diagnosis, and approximately 42% of patients with an intracranial process make several visits to various physicians between the onset and diagnosis. However, on clinical suspicion of a brain tumour, a wide range of neuroimaging techniques may be used to assess the diagnosis of paediatric brain lesions. In this review the authors, for ease of presentation, describe the clinical presentations of supratentorial, infratentorial and spinal cord astrocytomas as well as their radiological and pathological features, and discuss their differential diagnoses. Results/conclusions: Understanding and mastering the numerous imaging features of several subtypes of primary brain tumours affecting children, in addition to radiological features of non-tumoural disorders, remains a significant challenge and demands increased awareness of the paediatric brain diseases.
