Case report: late aggressive meningioma following prophylactic cranial irradiation for acute lymphoblastic leukaemia

The clinical, radiological and pathological findings in a 28-year-old female patient who developed aggressive meningioma 20 years after prophylatic cranial irradiation (PCI) for acute lymphoblastic leukaemia (ALL) are described here. Only four cases of late atypical/aggressive meningioma following PCI were detected in a thorough search of the literature. The high cure rate in childhood ALL, attributable to aggressive chemotherapy and PCI, is capable of inducing secondary brain tumour, including aggressive meningioma.
