Radiological Assessment of Paediatric Fungal Infections: A Pictorial Review With Focus on PET/MRI.

ABSTRACT

Paediatric invasive fungal infections have significantly increased over the past few decades, in particular among the immunocompromised population. Candida and Aspergillus spp. are still the most commonly isolated organisms. Image-based assessment of fungal infections can indeed be challenging especially in oncological patients where the differential diagnosis relative to other infections and neoplastic lesions cannot be often obvious. Therefore, the knowledge of the main radiological features associated with fungal infections is crucial to achieve an early correct diagnosis and address the most appropriate therapeutic approach. Thus, our aim was to review the main radiological features of paediatric fungal infections with particular focus on positron emission tomography/magnetic resonance imaging (PET/MRI), referring to the experience of our tertiary level hospital.
