Fig. 1B—8-year-old boy with chronic constipation. Pelvic radiograph
shows sacral abnormalities (arrow) with distal sacral dysplasia
taking the shape of a scimitar.
Fig. 1C—8-year-old boy with chronic constipation. Unenhanced axial T1
MRI image shows sacral hypoplasia with associated presacral bilobulated T1
hypointense mass lesion (arrow), whose signal is identical to
intrathecal CSF signal.
Fig. 1D—8-year-old boy with chronic constipation. Axial T2 MR image
also shows bilobular, well-defined, hyperintense presacral mass lesion
(arrow). Markedly distended rectosigmoid colon is obvious on this
sequence.
Fig. 1E—8-year-old boy with chronic constipation. Unenhanced sagittal
T1 and sagittal T2 images give lateral view of lesion (arrow), which
appears homogenous with low T1 and high T2 signal.
Fig. 1F—8-year-old boy with chronic constipation. Unenhanced sagittal
T1 and sagittal T2 images give lateral view of lesion (arrow), which
appears homogenous with low T1 and high T2 signal.
Fig. 1G—8-year-old boy with chronic constipation. Contrast-enhanced
T1 axial and sagittal images show peripheral enhancement with central fine
enhancing septation (arrow).
Fig. 1H—8-year-old boy with chronic constipation. Contrast-enhanced
T1 axial and sagittal images show peripheral enhancement with central fine
enhancing septation (arrow).
