Pediatric Neuroradiology (2022)-S2-CPD01-2022

Video Transcription

Video Summary

The video discusses pediatric neuroradiology, focusing on hyperdense and hypodense findings on head CT scans. It begins by detailing hyperdense findings such as hemorrhages and thrombosis, highlighting key CT characteristics of epidural, subdural, and intraparenchymal hemorrhages. It stresses the importance of examining coronal reconstructions in identifying subtle signs of trauma and hemorrhage.<br /><br />The presenter transitions to hypodense findings, discussing conditions like Posterior Reversible Encephalopathy Syndrome (PRESS) and stroke. They outline the significance of clinical history and MRI for differentiating between normal and abnormal findings, especially in cases like birth-related subdural hemorrhages.<br /><br />Additional mimickers such as pseudohyperdense and hypodense conditions like metabolic disorders are addressed. Emphasis is placed on juxtaposing clinical history with imaging for accurate diagnosis.<br /><br />Finally, the presenter touches on the importance of recognizing demyelinating diseases in children, such as multiple sclerosis, MOG-associated disorders, and neuromyelitis optica spectrum disorders. These conditions require early diagnosis, often relying heavily on MR imaging to distinguish among them due to overlap in symptoms and limited biomarkers. Key radiologic features aiding in diagnosis and understanding disease progression are highlighted.
