Masslike nodular enhancement form in spinal cord schistosomiasis. MR imaging of dorso-lumbar spine of case 6.
A, Sagittal T1-weighted SE (TR/TE: 530/20 ms) image showing mild expansion of the distal cord and conus medullaris by a poorly defined iso- to hypointense lesion (arrow).
B, Sagittal T2-weighted SE (TR/TE 5800/95 ms) image showing a hypointense lesion (arrow) surrounded by extensive perilesional hyperintense edema (arrowheads).
C, Postcontrast sagittal T1-weighted SE MR images (TR/TE: 520/20 ms). The lesion shows a solitary enhancing nodule (arrow).
D, Postcontrast axial image (TR/TE: 520/20 ms) documenting the intramedullary location of the enhancing spinal lesion (arrow).
