Abstract
The magnetic resonance images of 16 patients with intradural-extramedullary spinal
tumors, consisting of 11 neurinomas and five meningiomas were reviewed The neurinomas
appeared hypointense compared to the spinal cord on unenhanced T1-weighted images
(T1WI) in nine of 11 patients, and hyperintense on T2-weighted images (T2WI) in nine
of 11 patients. Neural foraminal extension was present in two cases. All 10 neurinomas
were markedly enhanced; six of them exhibited ring-like enhancement on Gadolinium-DTPA
(Gd-DTPA)-enhanced T1WI. The meningiomas appeared isointense on unenhanced T1WI in
four of five patients and on T2WI in three of four patients. Three meningiomas showed
moderate homogeneous contrast enhancement after the intravenous administration of
Gd-DTPA. It is concluded that careful scrutiny of magnetic resonance images facilitates
the differential diagnosis of spinal neurinomas and meningiomas.
