Sagittal (A and B) and axial (C) T2-W spinal MR images shows 2 focal hyperintensity with hypointense edge with surrounding spinal cord edema, this appearance described as << Popcorn >>.

Spine MR imaging revealed 2 intramedullary lesions widening the spinal cord at T6-T7 and T11-T12 with a popcorn appearance and heterogeneous signal in T1 and T2 weighted images, surrounded by a hypointense rim on all sequences (Figure 1) representing hemosiderin.
Susceptibility-weighted imaging gradient echo (GE) shows hypointense lesions "blooming."

Susceptibility-weighted imaging shows hypointense lesions "blooming" (Figure 2), with adjacent intramedullary hemorrhage, without enhancement (Figure 3).
Sagittal T1-W spinal MR images before (A) and after injection of Gadolinium (B) shows 2 focal hyperintensity with no enhancement (pink arrows), with linear hyperintensity reflect adjacent intramedullary bleeding (yellow arrow).
