[Abstract]:The female was 5 years old. After 4 weeks of treatment, there was no obvious cause for dysuria, no fever, nausea, vomiting, and no obvious improvement in the hospital, so the patient was transferred to our hospital. Ultrasound examination: bilateral kidney, ureter and bladder were not abnormal, the indwelling catheter was given, the urethral catheter was clamped intermittently, the symptom was not improved. Mr examination showed that the spinal cord was thickened in the spinal canal of T9L1, and the mixed T 1, slightly longer T 2 signal intensity could be seen (fig. 1 A 1 B, irregular shape). Long T 1, longer T 2 signal intensity and longer T 4 signal intensity can be seen in T 4 9 spinal cord. Contrast-enhanced T9~L1 showed significantly uneven enhancement of the spinal canal (Fig. 1C). Mr diagnosis: ependymoma. After resection of tumor, the spinal cord of T9 ~ (12) was spindle-shaped.
