“…The time duration between the lumbar puncture and the onset of the symptoms related to the epidermoid tumor ranges from 2 to 23 years. 9) In the present case, serial MR imaging of the lumbar region clearly demonstrated that epidermoid tumor can form and grow to symptomatic size within 14 years in an adult. Although the incidence is not high, we should be aware of the potential adverse complications of de novo epidermoid tumors in patients with persistent low back pain treated by repeated lumbar injection procedures.…”

“…9) In our case, T 1 -weighted MR imaging showed the mass as isointense, and T 2 -weighted imaging as slightly hyperintense. Although epidermoids are typically hypointense on T 1 -weighted imaging and hyperintense on T 2 -weighted imaging, the appearance varies from hypo-to isointense on both T 1 -and T 2 -weighted imaging.…”

“…2,3,5,8,10) Iatrogenic epidermoid tumor has also been associated with lumbar puncture as the cause of skin tissue coring. [2][3][4][5]9,10) However, these cases only included circumstantial evidence such as a history of multiple lumbar punctures at the same location as the tumor.…”

A 61-year-old female complained of low back pain, and had been treated by spinal anesthetic injection more than 70 times over 14 years. Magnetic resonance (MR) imaging, performed at the age of 47 years, revealed no abnormal lesion. However, she developed irritable hypesthetic pain in the left leg at 61 years of age. MR imaging revealed a round mass appearing isointense on the T 1 -weighted and slightly hyperintense on the T 2 -weighted images. Laminectomy revealed an epidermoid cyst, which was removed. This case clearly demonstrates that adults can acquire epidermoid tumor which very probably has an iatrogenic origin. The incidence of epidermoid tumor is low, but we should be aware of the potential adverse complications such as formation of epidermoid tumors after lumbar puncture.

“…Iatrogenic epidermoid tumors are rare, but intraspinal examples have been associated with the transfer of cutaneous epithelium fragments to the subarachnoid space during diagnostic procedures such as lumbar puncture. 3,4,8,[10][11][12] Epidermoid tumors are slow growing, so the symptoms may only develop 3-12 years after lumbar puncture. 4,8,10,12) Only one case of iatrogenic intracranial epidermoid tumor has occurred after multiple percutaneous subdural aspirations.…”

A 66-year-old man presented with complaints of numbness for the past 5 years and progressive motor weakness of the right leg for the previous 2 months. Magnetic resonance imaging revealed large intraand extracranial tumors in the frontoparietal region. Physical examination suggested the extracranial lesion was a subcutaneous lipoma, which had been partially resected 60 years before, connected to the intracranial lesion via a defect of the skull. Gross total removal of the tumors was performed. Histological examination showed the intracranial lesion was epidermoid tumor, and connected to the extracranial lipoma by a lipoma bridge. The symptoms improved remarkably following surgery. This case of intracranial epidermoid tumor associated with intra-extracranial lipoma indicates that implantation of skin tissue in childhood carries the risk of epidermoid tumor even after several decades. Neuroimaging screening is recommended to detect the development of any intracranial components.
