Iatrogenic lumbar tumors are usually occur in childhood, through implantation of epidermal cells to the intraspinal space during repetitive lumbar puncture. Cells iatrogenically implanted into the spinal canal during lumbar puncture can slowly grow until symptomatic. Diagnosis can be difficult and is often delayed. MRI appears to offer some advantages in diagnosis provided that gadolinium is used. They are rarely seen in adults. We present successful surgical treatment of two lumbar epidermoid tumor cases one 64, and the other 34 year old whom had repetitive LP application in their medical history.
