Methods

We performed a retrospective case series review by querying our institutional pathological database for GCTs, PCTs, and SCOs. Surgical interventions occurred between 1997-2017 on all patients. We received approval from our local Institutional Review Board for this study. Out of 16 patients found, 11 patients (4 GCTs, 4 PCTs, and 3 SCOs) had clinical records sufficient to conduct a retrospective review. Clinic notes from surgical and consulting specialties were used to assess demographics, presenting symptoms, endocrine status, and post-operative complications and health status. Operative reports were reviewed for surgical characteristics. Magnetic resonance imaging (MRI) files, in addition to radiologic reports, were used to assess tumor size, location, and recurrence. Immunohistochemical studies were performed by our institutional neuropathologists using standard techniques. On initiation of this study, all tumor samples were evaluated for TTF-1 staining. Categorical variables were analyzed with a two-tailed Fisher exact tests. Continuous variables were analys
