title: The right amygdalar tumor presenting with symptoms of separation anxiety disorder (SAD): a case report.
abstract: A patient with an astrocytoma of the right-sided amygdala developed symptoms of separation anxiety disorders (SADs). These symptoms significantly subsided after tumor resection. The temporal relationship suggested that the amygdalar tumor could result in the specific symptoms. To our knowledge, this is the first report of SAD as one manifestation of the amygdalar tumor. The tumorigenesis of amygdala resulted in impaired regulation and abnormal activity associated with anticipating anxiety and conditioning. It deserves clinical attention to early detection and intervention.
