Sagittal MRI T1-weighted (A), T2-weighted (B), STIR
(C) and T1-weighted sequences with fat saturation following
intravenous contrast injection (D) demonstrating an elongated, expansile
well-delimited lesion with regular contour, located in the epidural space of the
posterior region of the dorsal spine, extending from D5 to D7. The lesion presents
intermediate signal on T1-, marked hypersignal on T2-weighted and STIR sequences,
with intense and homogeneous contrast enhancement, suggestive of hemangioma. Such a
tumor causes remarkable narrowing of the rachidian canal, determining high signal
intensity in the spinal cord (better visualized on STIR sequences) due to compressive
myelopathy.

Such a lesion determined a significant narrowing of the rachidian canal and medullary compression on the corresponding segments, with consequential medullary hypersignal on T2-weighted and STIR sequences compatible with compressive myelopathy (Figure 1).
