[Arteriography of intraspinal ependymomas]

Area of Science:

• Neuroradiology
• Diagnostic Imaging

Background:

• Spinal ependymomas are tumors arising from ependymal cells within the spinal cord.
• Angiography is an imaging technique used to visualize blood vessels.

Observation:

• Eleven cases of spinal ependymomas were evaluated using spinal angiography.
• A tumoral blush, indicative of tumor vascularity, was observed in four cases.
• Indirect signs suggestive of spinal tumors were noted in five cases.

Findings:

• Direct opacification of caudal ependymomas can be valuable.
• Spinal angiography is particularly useful for differentiating ependymomas from arteriovenous malformations.
• It aids diagnosis when spinal subarachnoid hemorrhage (S.A.H.) or abnormal myelographic vascular markings are present.

Implications:

• Spinal angiography offers critical diagnostic information for spinal ependymomas.
• This technique is essential for differential diagnosis in complex spinal vascular cases.
• Enhanced visualization aids in surgical planning and patient management.
