Initial magnetic resonance imaging in 2003 showing a large syringomyelic cavity extending from the C1 level to the conus (a and b). Head computed tomography and MR angiography reveal hydrocephalus and multiple aneurysms (c and d)

She had CM1 with cerebral hydrocephalus and a large syringomyelia extending from C1 level to the conus [Figure 1].
MR images (a) T1-weighted image, (c- f) T2-weighted images) show a heterogeneous mass on the caudal end of the syringomyelic cavity suggesting hematomyelia. Partial gadolinium enhancement is revealed at the centre of the hematomyelia (b, arrowed)

Both T1- and T2-weighted images showed a heterogeneous mass on the caudal end of the syringomyelic cavity, suggesting hematomyelia [Figure 2].
Postoperative MR images of the lumbosacral lesion (a) T2-weighted sagittal image (b) T2-weighted axial image at the T12 vertebral level (c) T2-weighted axial image at the L1 vertebral level and (d) at the L2 vertebral level revealing shrinkage of the hematoma cavity with peripheral hemosiderin deposition

Repeated MR imaging performed up to 3 years after the operation showed marked reduction of spinal cord diameter and shrinkage of the syringeal cavity [Figure 3].
