ABSTRACT
AIM:
To characterise and evaluate magnetic resonance imaging (MRI) images for their clinical value in diagnosing and assessing intraspinal mature teratoma. MATERIALS ANDMETHODS:
MRI images obtained from eight patients with a histopathologically verified intraspinal mature teratoma were analysed retrospectively regarding tumour location, size, and margins. Additionally, the signal intensity and enhancement pattern on MRI and other associated malformations were also assessed.RESULTS:
Three cases that contained fatty tissue showed markedly heterogeneous hyperintense signalling on T1-weighted images, and mixed hyperintense and hypointense signalling on T2-weighted images and fat-suppression sequences. All three of those cases showed an irregular peripheral fatty tissue signal, and one case showed additional patches of an interspersed calcification signal. The remaining five cases without fatty tissue displayed heterogeneous hyperintense signalling on T1-weighted images and T2-weighted images, and also on fat-suppression sequences. Four of the five cases showed additional patches of interspersed nodular calcification signals. Contrast-enhanced MRI images showed only slight enhancement (n=3).CONCLUSIONS:
MRI is regarded as the reference standard diagnostic technique to reveal the location of teratomas and the degree of spinal cord involvement. In most cases, MRI provides accurate anatomical and histological information, which is necessary for patients with suspected intraspinal mature teratoma.
