RT Journal Article SR Electronic T1 Unilateral Transpedicular Course of an Ascending Lumbar Vein through a Pedicular Foramen Mimicking a Lytic Lesion: An Anatomic Variant JF American Journal of Neuroradiology JO Am.

Recognition of this anatomic variation is important to avoid diagnostic misinterpretations and transpedicular interventions such as percutaneous vertebroplasty or surgical instrumentation that may result in excessive hemorrhage and inadvertent leak of cement when it is present.
