Although the association of spinal lumbosacral dysraphism and congenital spinal dermoid tumors is well known, the association of craniocervical spinal anomalies and posterior fossa dermoids has only been recognized recently. Advances in imaging technology and awareness of the association likely contribute to an increase in recently reported cases.

Key highlights: Tabular columns organized by anatomical abnormality include imaging findings and a summary of key clinical data that correlates to the images Congenital/developmental abnormalities, spinal deformities, and acquired pathologies in both children and adults Lesions organized by region including dural, intradural extramedullary, extra-dural, and sacrum More than 600 figures illustra...

Energy metabolism measurements in spinal cord tumors, as well as in osseous spinal tumors/metastasis in vivo, are rarely performed only with molecular imaging (MI) by positron emission tomography (PET). This imaging modality developed from a small number of basic clinical science investigations followed by subsequent work that influenced and enhanced the research of others. Apart from precise a...

BACKGROUND AND PURPOSE Hemangioblastomas (HBs) are rare lesions accounting for 1-5% of all spinal cord tumors. Seventy-five percent of spinal HBs are intramedullary. Lesions of the conus medullaris and the cauda equina are uncommon, and the filum terminale location is very rare. HBs of the lower spinal region are highly vascular tumors requiring surgery that is potentially complicated by excess...

Background and Importance: Disk sequestration can be defined as a herniated disk with perforation of the fibrous ring (or outermost annulus fibrosus) and posterior longitudinal ligament with migration of the disk fragment to the epidural space. Even after the introduction of high-resolution magnetic resonance imaging (MRI), it is still frequently misinterpreted as neoplastic masses. U...

Chordomas are rare tumors from primitive notochord. They are usually located at sacrococcygeal region when it affects the spine. We present a case of giant chordoma in the thoracolumbar spine in Peru. A 43-year-old woman came to the hospital in Huanuco due to back pain and sensorymotor alterations in the lower limbs. Imaging confirmed an unresectable tumor involving the spine. Two years later, ...
