Purpose Congenital spinal lipomatous malformations are a diverse group of lesions. The complexity of these lesions has led to considerable variability in the nomenclature used to describe and classify them. As a result there sometimes is disconnect between the radiology report and what the pediatric neurosurgeon wants and needs to know. The goals of this electronic educational exhibit are as follows: 1. To provide a image-rich, illustrative review of the nomenclature and classification scheme of the various congenital lipomatous malformations. Emphasis will be on describing a simplistic, widely accepted classification scheme based on the whether or not there is a open or closed spinal dysraphism and based on the presence or absence of a dural defect. 2. To describe a structured approach for interpreting and desciribing the imaging findings of these lesions. Key reporting attributes that should be part of every structured report are discussed. Emphasis will be on using terminology and pertinent positive and negatives that are critical for the referring pediatric neurorsurgeon to know based on the preferences at our institution. 3. To describe the standard imaging protocol for these lesions. Particular empasis will be on discussion of use of CISS/FIESTA sequences that are commonly used at our institution to image these lesions. These sequences are especially useful for visualization of sinus tracts. Materials & Methods N/A Results N/A Conclusion This image rich educational exhibit will provide a review of the nomenclature and classification scheme used to describe congenital spinal lipomatous malformations. The reader will be led through an overview of a structured approach to interpreting and reporting these lesions. Key reporting attributes that the surgeon needs to know will be discussed. The reader will also become familiar with commonly used sequences for imaging these lesions as well as the use of specific sequences such as CISS/FIESTA that are particulary useful in imaging sinus tracts based on the experience at our institution.
