Imaging 'the lost tribe': a review of adolescent cancer imaging. Part 1

Although a small proportion of all cancer registrations, malignancy in adolescence and young adulthood remains the most common natural cause of death in this age group. Advances in the management and outcomes of childhood cancer have not been matched within the adolescent population, with increasing incidence and poorer survival seen amongst teenagers with cancer compared with other populations. There have been increasing moves towards specific adolescent oncology centres, with the aim of centralizing expertise, however, 'adolescent imaging' does not exist as a specialty in the same way that paediatric imaging does, with responsibility for imaging adolescent patients sometimes falling to paediatric radiologists and sometimes to 'adult' radiologists, usually with a specific interest in a tumour type or body system. In this article, imaging of the more common malignancies, encountered in adolescent patients is reviewed. Complications of treatment are reviewed in another article to give an overview of adolescent oncology imaging practice.
