    Author: Ferguson SD, Waguespack SG, Langford LA, Ater JL, McCutcheon IE.
    Journal: Childs Nerv Syst; 2015 May; 31(5):777-84. PubMed ID: 25503249.
    Abstract:
    INTRODUCTION: Juvenile xanthogranuloma (JXG) is a histiocytic condition in the spectrum of non-Langerhans histiocytosis that preferentially affects children. Rarely this condition can involve the central nervous system (CNS) with devastating consequences. METHODS: The authors report the unique case of an 11-year-old child who initially presented with a sellar lesion without evidence of the cutaneous stigmata typical of JXG. She was later discovered to have JXG following initial diagnosis of granulomatous hypophysitis, with development of widespread intracranial disease and subsequent neurological deterioration. She underwent subtotal resection of her sellar lesion followed by whole brain radiation and systemic chemotherapy; however, she succumbed to her disseminated disease within 1 month of the JXG diagnosis. CONCLUSIONS: This is a rare case of fatal disseminated intracranial JXG without cutaneous manifestations. Additionally, the initial presentation as a sellar lesion is particularly unusual and seldom described in the literature.
