F-DOPA PET/CT scan has an important prognostic value in predicting disease progression and mortality rate.

A 52-year-old man underwent Ga DOTATOC PET/CT scan for postsurgical staging of a neuroendocrine tumor of the lung. The PET images showed a single focus of increased activity in a soft tissue nodule located posteriorly to a cervical vertebra. Surgical removal of the lesion led to the histological diagnosis of retiform hemangioendothelioma.
