(
A
) Maximum intensity projection of coronal computed tomographic myelogram demonstrating diastematomyelia of the lower thoracic spinal cord as well as expansile intradural multiloculated cyst, likely intramedullary in origin arising from the right hemicord and does not fill with contrast. (
B
) Intraoperative picture of intramedullary cyst. (
C
) Axial T2 magnetic resonance imaging (MRI) demonstrating compression of the two spinal cords, with right (gray arrows) more compressed than left (white arrows). (
D
) Sagittal T2 MRI of the spine showing compression of the left hemicord by the cyst and causing syrinx.

The lesion now spanned T6-11 and measured 2.1 x 3.0 cm in its maximum anteroposterior and transverse dimensions with compression at T9-11, with no abnormal enhancement seen on postcontrast imaging ( Fig. 1 ).
