An intramedullary cervical cord lesion in a 12-year-old girl

摘要

A 12-year-old girl visited our hospital with chief complaints of numbness and weakness in her right extremities. The symptoms tended to get worse progressively for 2 weeks. Other system examinations were normal, including lymphatic examination. Routine blood tests and blood biochemical measurements were within reference ranges. MRI showed a homogeneous isointense mass lesion on Tl-weighted and subtle hyperintensity on T2-weighted images at the levels of C1-T6 (Fig. 1A,B), with marked homogeneous enhancement on enhanced Tl-weighted MRI at the levels of C4-C5 (Fig. 2A-C). Based on the MRI results, the mass was at the C4-C5 level and the T2-weighted image showed a secondary edema from Cl to T6. An occipital para-midline approach was done and the lesion was completely removed. The lesion was intramed-ullary, well-defined, grayish red with solid consistency (1 cm x 1 cm x 1.5 cm). Initially diagnosis was "inflammation" on frozen section.
