Extraparenchymal Lesions in Pediatric Patients
Extraparenchymal lesions of childhood include neoplastic and nonneoplastic entities. Lesions affecting children are different from the most common entities affecting adults. Although there are imaging features that are highly suggestive of extraparenchymal origin, it can be difficult to distinguish extraparenchymal from intraparenchymal lesions. MR imaging is the examination of choice for the evaluation of extraparenchymal lesions given greater sensitivity and anatomic detail. Syndromic associations should be considered, especially for unusual lesions in the pediatric age group such as meningioma and schwannoma.
