Objective And Importance:
Fibrous hamartoma of infancy (FHI) in the spinal cord is very rare. It is characterized histopathologically by three elements: fibrous, adipose, and myxoid mesenchymal tissues.
Clinical Presentation:
A 10-month-old boy presented with paraparesis. Magnetic resonance imaging showed a large intradural mass that occupied the space between the T10 and L4 levels.
Intervention:
We performed partial removal of the mass. Histopathological examination of the lesion revealed that it was composed of collagen bundles and fibrous tissue interspersed with adipose tissue, mesenchymal tissue, and glial tissue, and it was diagnosed as FHI.
Conclusion:
FHI in the central nervous system, especially in the spine, is very rare, and the presence of glial tissue admixed with particular components of FHI is quite exceptional.
