Intradural spinal mass lesions (an approach) | Radiology …
2024年7月26日 · MRI is the modality of choice for the assessment of lesions within the spinal canal as it has exquisite anatomical contrast and structural resolution, is able to image all compartments, and affords assessment for the presence …
Masses in and Around the Spine - SpringerLink
2024年2月11日 · To understand the anatomy of the paraspinal space, the intercostal space, the epidural space, and the vertebrae together with the interconnecting pathways. To understand imaging features of common masses in and around the spine. It is the role of the radiologist to detect each mass imaged in and around the spine.
Spinal Epidural Hemangiomas: Various Types of MR Imaging …
In summary, a spinal epidural hemangioma could be suspected if there is either a solid hypervascular mass that involves multiple levels of the spine or a cystlike mass with T1 hyperintensity. Our cases of the type D lesions showed diffuse areas of organized hematoma.
Primary extradural tumors of the spinal column: A comprehensive ...
This comprehensive overview summarizes clinical knowledge as well as imaging findings of all primary, extradural spinal tumors described in the literature. We describe our treatment algorithms, which is individualized for each tumor entity and loosely based on Enneking's classification system, and modified by contemporary imaging protocols.
Magnetic resonance imaging of spinal epidural lesions
Magnetic resonance imaging is the modality of choice for evaluating osseous and extraosseous extent of the lesion and involvement of the nerve roots and spinal cord. On T1-weighted sequences, vertebral metastasis and epidural soft tissue commonly demonstrate low signal relative to muscle.
Primary spinal epidural lymphomas - PMC - National Center for ...
MRI and myelogram have been the most preferred imaging modalities for spinal epidural tumors. Although contrast MRI is the preferred imaging modality by most surgeons, Monnard et al used MRI for localizing the tumor in only 65% of their patients.
Thoracic Spine Epidural Mass | Eurorad
2007年7月26日 · MR (1.5 Tesla) imaging of the thoracic spine identified an intraspinal posterior epidural mass, tubular, with well-defined limits, upper and lower tapering, extending from the lower plane of T5 to the upper plane of T8 (two vertebral bodies in length).
MRI Features of Spinal Epidural Angiolipomas - PMC
The mass, with the spindle shape, was located in the posterior epidural space and extended parallel to the long axis of the spine. All lesions contained a fat and vascular element. The vascular content, correlating with the presence of hypointense regions on T1-weighted imaging (T1WI) and hyperintense signals on T2-weighted imaging, had marked ...
Spinal Tumors - Radiology Key
2019年8月20日 · MRI is essential in identifying epidural mass and spinal cord or nerve root compression. Unfortunately, conventional MRI often cannot differentiate changes due to treatment, fracture, and tumor. Spinal marrow signal that is hypointense to muscle or disks on T1-weighted images should be considered abnormal (see Figs. 30-16B and 30-17B ).
