Background: Reversible bilateral striatal necrosis associated with Mycoplasma pneumoniae (M. pneumoniae) infection is a rare neurological disease. The exact pathogenic mechanism remains unknown. Patient: We report reversible bilateral striatal lesions with a favorable outcome secondary to M. pneumoniae infection in an 8-year-old Chinese girl. Cranial MRI showed abnormal signals in bilateral striatum, which disappeared 8months later. To better understand the pathogenesis of this encephalopathy, we examined cytokines levels in serum and cerebrospinal fluid from this patient. The results revealed the concentrations of interleukin-6 and interleukin-8 increased significantly in serum (26pg/mL and 66pg/mL, respectively) and cerebrospinal fluid (122pg/mL and 325pg/mL, respectively), and were reduced markedly after the therapy. Intrathecal production of interleukin-6 and interleukin-8 is probably related to the pathogenesis of striatal lesions caused by M. pneumoniae. These cytokines may cause local vascular injury, and finally leading to local vascular occlusion. Conclusion: Our results suggest that interleukin-6 and interleukin-8 may play important roles in the pathogenesis of this disease. This is the first report to describe the role of cytokines in this condition and relevant literature is reviewed. Our findings may lead to better understanding of the pathogenesis of M. pneumoniae-associated striatal lesions. |
