Morphological and functional study of a case of superficial siderosis of the central nervous system

We here describe a case of superficial siderosis (SS) of the central nervous system (CNS), occurring in a patient with a previous lesion of the brachial plexus. Of the only 96 cases that have been described in the literature so far, there are now five with a positive history of a lesion due to the evulsion of the roots of the brachial plexus. This is the first time that, in addition to CT and MRI morphological investigations, an SS patient has also been studied metabolically by means of PET in an attempt to find new clues that may help to clarify the pathogenesis of the disease.
