The association of neuroblastoma and myoclonic encephalopathy: an imaging approach
Insights
Myoclonic encephalopathy in children often links to neurogenic tumors. Prompt imaging, including chest X-rays and abdominal CT scans, is crucial for early detection and diagnosis.
Area of Science:
- Pediatric Neurology
- Medical Imaging
- Oncology
Background:
- Myoclonic encephalopathy is a rare pediatric neurological disorder.
- Approximately 50% of cases are associated with neurogenic tumors of ganglion-cell origin.
Observation:
- A review of existing literature and personal cases highlights the importance of specific imaging modalities.
- Two recent infant cases underscore the diagnostic approach.
Findings:
- Recommended initial imaging includes chest radiography and abdominal computed tomography (CT).
- Further investigations like ultrasonography, neck CT, and chest CT myelography may be necessary for specific cases.
Implications:
- An expedited clinical and imaging assessment is vital for identifying neurogenic tumors in children with opsomyoclonus.
- Early detection facilitates timely intervention and improves patient outcomes.
Abstract:
Myoclonic encephalopathy is a unique clinical syndrome of infants and children that is associated with a neurogenic tumor of ganglion-cell origin in approximately half of cases. A review of the literature as well as our personal experience with two recent infants suggests an imaging approach that includes chest radiography and abdominal computed tomography (CT). Ultrasonography, neck CT, and chest CT myelography may be required in selected patients. An expedient clinical and imaging evaluation of infants and children with opsomyoclonus is important to detect those patients with neurogenic tumors.
