Neurosurgical treatment of Cushing disease in pediatric patients: case series and review of literature

Abstract

Aim: Pituitary adenomas are rare in childhood in contrast with adults. Adrenocorticotropic hormone (ACTH)-secreting adenomas account for Cushing’s disease (CD) which is the most common form of ACTH-dependent Cushing’s syndrome (CS). Treatment strategies are generally based on data of adult CD patients, although some difficulties and differences exist in pediatric patients. The aim of this study is to share our experience of 10 children and adolescents with CD. Patients and method: Medical records, images, and operative notes of 10 consecutive children and adolescents who underwent transsphenoidal surgery for CD between 1999 and 2014 in Cerrahpasa Faculty of Medicine were retrospectively reviewed. Mean age at operation was 14.8 ± 4.2 years (range 5–18). The mean length of symptoms was 24.2 months. The mean follow-up period was 11 years (range 4 to 19 years). Results: Mean preoperative cortisol level was 23.435 ?g/dl (range 8.81–59.8 ?g/dl). Mean preoperative ACTH level was 57.358 ?g/dl (range 28.9–139.9 ?g/dl). MR images localized microadenoma in three patients (30%), macroadenoma in four patients (40%) in our series. Transsphenoidal microsurgery and endoscopic transsphenoidal surgery were performed in 8 and 2 patients respectively. Remission was provided in 8 patients (80%). Five patients (50%) met remission criteria after initial operations. Three patients (30%) underwent additional operations to meet remission criteria. Conclusion: Transsphenoidal surgery remains the mainstay therapy for CD in pediatric patients as well as adults. It is an effective treatment option with low rate of complications. Both endoscopic and microscopic approaches provide safe access to sella and satisfactory surgical results. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature.
