ABSTRACT
The spleen is considered a "forgotten organ" by most radiologists and paediatricians despite being affected in many clinical paediatric situations. While it is the organ most often affected in paediatric abdominal trauma, non-traumatic spleen disorders are less well known. The spleen is well visualised by any imaging technique: ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI); the former is used most often in children. Using imaging techniques to determine the features of splenic anomalies, both congenital and acquired, enables a correct diagnostic approach, avoids unnecessary surgical procedures or biopsies, and helps the clinician to prescribe appropriate treatment. Our aim was to show the behaviour of the spleen in children using the different imaging techniques: its normal anatomy, the principal anatomical variants and the most common spleen disorder correlating with clinical symptoms, serology and histology.
