This entity typically presents as a cutaneous head or neck nodule but can manifest with more systemic involvement including in the central nervous system. However, currently there is limited information regarding specific imaging features differentiating JXG from other neuropathological entities, with diagnosis typically made only after tissue sampling. The authors reviewed the initial images of a young patient with shunt-treated hydrocephalus and enlarging, chronic, extraaxial processes presumed to reflect subdural collections from overshunting, and they examine the operative discovery of a mass lesion that was pathologically proven to be JXG. Their results incorporate the important associated histological and advanced imaging features, including previously unreported metabolic activity on FDG PET. Ultimately, the case underscores the need to consider JXG in differential diagnoses of pediatric intracranial masses and highlights the potential role of PET in the initial diagnosis and response to treatment.<\/jats:p>","DOI":"10.3171\/2020.4.peds19624","type":"journal-article","created":{"date-parts":[[2020,7,17]],"date-time":"2020-07-17T07:07:55Z","timestamp":1594969675000},"page":"449-453","source":"Crossref","is-referenced-by-count":0,"title":["Juvenile xanthogranuloma of the subdural spaces mimicking chronic hematoma with positive FDG uptake on PET: case report"],"prefix":"10.3171","volume":"26","author":[{"given":"Jacob A.","family":"Kahn","sequence":"first","affiliation":[{"name":"Departments of Radiology,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey T.","family":"Waltz","sequence":"additional","affiliation":[{"name":"Departments of Radiology,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ramin M.","family":"Eskandari","sequence":"additional","affiliation":[{"name":"Neurosurgery, and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cynthia T.","family":"Welsh","sequence":"additional","affiliation":[{"name":"Pathology, Medical University of South Carolina, Charleston, South Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael U.","family":"Antonucci","sequence":"additional","affiliation":[{"name":"Departments of Radiology,"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"issue":"2","key":"b1","series-title":"J Pediatr","doi-asserted-by":"publisher","first-page":"227","DOI":"10.1016\/S0022-3476(96)70247-0","article-title":"Juvenile xanthogranuloma: forms of systemic disease and their clinical implications","volume":"129","author":"Freyer DR","year":"1996","unstructured":"Freyer DR, Kennedy R, Bostrom BC,  Juvenile xanthogranuloma: forms of systemic disease and their clinical implications.
