Tethered spinal cord

Clinical History: 
This 6-year-old girl was referred to physical therapy for baseline evaluation in the spina bifida clinic and for assessment of neurogenic bowel and bladder dysfunction. At birth, this patient was diagnosed with sacral dysgenesis along with tethered cord and a lipoma within the sacral spinal canal.

Diagnosis:
Metastatic cervical carcinoma to the pituitary.

MR technique: 
Scans were acquired on a 1.5T Siemens MR unit. (A) Sagittal pre-contrast spin echo T1-weighted (TR/TE 665/7.9 ms, scantime 3:35 min:sec) and (B, C) sagittal turbo spin echo T2-weighted (TR/TE 3130/98ms, scantime 3:32 min:sec) were obtained. The slice thickness was 4 mm in each instance.

Imaging Findings:
The spinal cord extends to the L5-S1 level and merges with a fatty mass within the sacral spinal canal. The sacral spinal cord itself appears enlarged. This heterogeneous mass is bright on T1-weighted images, suggesting a high fat content. Its inferior aspect merges with fat in the spinal canal deep to a dysraphic defect. No concomitant diastematomyelia or syringomyelia is identified.
