Polysplenia syndrome associates multiple spleens to other malformations, most frequently cardiac, vascular, visceral, and biliary malformations. Polysplenia has been described mainly in childhood owing to critical anatomic malformations related to cardiac defects or biliary atresia. We present a case of polysplenia syndrome found in a 58-year-old man. Only those with mild anatomical abnormalities reach adulthood without a diagnosis. Radiological examinations are helpful to the diagnosis by ascertaining the location and number of spleens, location of other organs in the chest and abdomen, and identification of other associated anomalies.

Like any organ in children, the ear has particular anatomical features that are well shown in imaging. The petrous bone computed tomography (CT) is a valuable tool for diagnosing ear pathologies and evaluating surgical possibilities. In children, the ear has the peculiarity of having the morphology and size of adults, and the only difference resides in the components of the middle and inner ear related to the growth of the temporal bone and the state of ossification which are progressive with age. Some aspects of growth can simulate pathology and must be known. The pneumatisation of the temporal bone occurs gradually after birth and in several outbreaks until adulthood. The external auditory canal, the internal auditory meatus and the petromastoid canal progressively reach the adult aspect because of the growth of the petrous bone. This work aims to highlight the particularities of the petrous bone CT in pediatrics, since it has become widely used in the exploration of malformations, trauma, infectious complications of the ear and in the assessment of deafness.

Pseudo papillary and solid pancreatic tumor (PPSPT) is a rare tumor that occurs almost exclusively in adolescents and young women. Radiological exploration is mainly based on ultrasound and CT, which can often guide the diagnosis. We report the case of a 12-year-old girl, who was referred for suspicion of a hydatid cyst of the liver. Abdominal ultrasound showed a large solid-cystic mass, in contact with the hepatic hilum. Abdominal CT allowed a better study of the localization and the anatomical relationships of the mass. It was pancreatic head tumor encasing the portal vein and compressing the common biliary duct. The CT features suggest more a PPSPT or a pancreatoblastoma. The pathological study after surgery confirmed the diagnosis of PPSPT.
