Objectives
to report a surgical site infection from Aspergillus after a lumbar discectomy. Aspergillus is ubiquitous fungus. People with normal immunity are usually not infected by it, however, surgical site infection from it often developed even in normal population.
Materials and Methods
The diagnostic and therapeutic experience of 55-year-old male patient who underwent L45 discectomy who had surgical site infection from Aspergillus was reviewed.
Results
He had 4 times surgical treatment and empirical antibiotic therapy due to progressive extension of infection without microbiologic confirmation. Aspergillus flavus was identified at 5th operation and he was cured by adding an anti-fungal agent.
Conclusions
An Aspergillus infection after an operation can be developed even in normal immunity population. If a surgical site infection patient without fever and draining sinus does not improve by conventional treatment, Aspergillus infection should be considered.

Spinal cord injury is a devastating condition that leaves permeant disability. Surgical decompression and stabilization with various pharmacological treatments have been tried to prevent secondary injury, however, their results have been disappointing. Therefore, novel therapeutic options are required enthusiastically. Cell transplantation that has the potential of neuroregenerative and neuroprotective ability is regarded as a promising remedy. We would like to describe about the micro-anatomy and the mechanism of injury of spinal cord injury. We also delineate transplanted cells; embryonic stem cell, induced pluripotent stem cell, mesenchymal stem cell as stem cells and Schwan cell, olfactory ensheathing cell as supporting cells with brief reviews of their experimental results.
