Significantly Elevated FDG Activity in Neurothekeoma.

Neurothekeoma is a very rare cutaneous lesion affecting mainly young patients. The lesion is generally benign. We report here that intense FDG activity on PET/CT was noted at the site of primary neurothekeoma of the right shoulder in a 16-year-old boy. Abnormal FDG activity was also seen in the metastatic neurothekeoma in the lung in the same patient 2 years later.
