Traumatic lesions of adrenal glands in paediatrics: about three cases.
Pediatric adrenal injuries, in blunt thoracoabdominal trauma, are rare and usually associated with traumatic liver and kidney lesions. This paper aims to present imaging findings and possible adrenal involvement in blunt abdominal traumas in childhood. We report three cases of thoracoabdominal trauma with adrenal involvement. Two patients were polytraumatised in car accidents. The third case was unusual because of the mild trauma. The adrenals lesions were right-sided in all cases. Post-traumatic adrenal contusion/haematoma may arise not only because of a direct trauma but also as a consequence of a sudden increase in the pressure in the inferior vena cava system-adrenal veins. This is why adrenal haemorrhage is not directly proportional to the trauma: compression of the inferior vena cava leads to increased pressure in the adrenal venous circulation, which supports the parenchymal lesion. The right adrenal gland is more frequently injured than the left gland: it can be easily compressed between the liver, spine and kidney, and its venous drainage flows directly into the inferior vena cava.
