Chiasmatic-Hypothalamic Masses in Adults: A Case Series and Review of the Literature

ABSTRACT Chiasmatic‐hypothalamic masses are commonly seen in children with neurofibromatosis type 1 and often demonstrate a benign clinical course. These masses are, however, rare in adults and require tissue sampling for diagnosis. Here, we present four cases of chiasmatic‐hypothalamic masses in adults with pathologically proven diagnoses. We also provide a review of the literature and propose a limited differential in this age group.
