Erdheim-Chester disease (ECD) is a rare form of non-Langerhans cell histiocytosis characterized by a xanthogranulomatous infiltration of tissues by spumous histiocytes. Neurological involvement is frequent, but ischemic strokes have been exceptionally described. We report the case of a 68-year-old woman who presented with an acute ischemic stroke associated with a multisystemic disorder including insipidus diabetes, infiltration of the aorta and the carotid arteries, perirenal infiltration, aortitis, and lytic bone lesions. The surgical biopsy of a lumbar vertebra revealed an infiltration of spumous macrophages consistent with ECD. Many ischemic symptoms can occur in ECD. Ischemic strokes, infrequently reported, might be caused by perivascular infiltration and adventitial fibrosis of the supra-aortic trunks or intracranial arteries.

Here, the authors present the first documented case of a patient developing central nervous system (CNS) vasculitis secondary to Langerhans cell histiocytosis (LCH) ultimately leading to stroke. LCH is a rare histiocytic disorder affecting males and females equally and typically presents in pediatric patients with a median age of 30 months. Presentation of the disease can be single-site or multisystem; and, classification of treatment is further demarcated by high risk and low risk depending on the organ systems involved. Treatment of LCH typically involves vinblastine and prednisone, as well as salvage treatment as needed.
