en Gamma Knife Radiosurgery Research <p style="text-align: justify;"><strong>Background & Aim: </strong>We described the presentation, management and subsequent treatment outcomes of children and adolescents diagnosed with a pituitary adenoma in a joint neuroendocrine setting followed up by a single service as well as assessing long-term outcomes in terms of endocrine status and neurology symptoms.</p> <p style="text-align: justify;"><strong>Methods & Materials/Patients:</strong> A total of 21 participants with histologically verified pituitary adenoma between January 2011 and June 2014 were studied. Patients&#39; data from clinical, radiological and pathological records were analyzed using SPSS (Version 16).</p> <p style="text-align: justify;"><strong>Results: </strong>All these children and adolescents with pituitary adenomas were managed with microscopic transsphenoidal surgery. The most common symptom was Cushing (47.6%, n=10). The functional type (76.2%, n=16) was more than the non-functional. The post-operative control MRI of most of them was clear (90.5%, n=19). The lab control of most of them was normal (76.2%, n=16). Apoplexy was seen in 5 patients (33.8%). Gross-total resection (GTR; 100% tumor removal as judged by early post-operative imaging) was achieved in 19 cases. Only one of these patients showed evidence of radiologic recurrence.</p> <p style="text-align: justify;"><strong>Conclusion</strong>: In our study, all patients underwent microscopic transsphenoidal surgery due to limitation of endoscopic approach in pediatric and avoided wide anatomical deficit. Doing a comparative study between these two approaches will bring about promising results.</p> Pediatric Pituitary Adenoma, Apoplexy, Transsphenoidal Approach, Functional Pituitary Adenomas, Nonfunctional Pituitary Adenomas 11 15 http://irjns.org/browse.php?a_code=A-10-100-28&slc_lang=en&sid=1 Masoud Shirvani مسعود شیروانی 10031947532846003019 10031947532846003019 No MD, Neurosurgeon, Department of Neurosurgery, Milad Hospital, Tehran, Iran Alireza Hajimirzabeigi علیرضا حاجی میرزابیگی 10031947532846003020 10031947532846003020 No MD, Department of Neurosurgery, Milad Hospital, Tehran, Iran Rozita Jafari رزیتا جعفری 10031947532846003021 10031947532846003021 No Surgeon, Department of Otolaryngology, Head and Neck Surgery, Tracheal Research Center, Shahid Beheshti University of Medical Sciences, Masih Daneshvari, Tehran, Iran Morteza Khatami مرتضی خاتمی 10031947532846003022 10031947532846003022 No MD, Guilan Road Trauma Research Center, Guilan University of Medical Sciences, Guilan, Iran Alireza Razzaghi علیرضا رزاقی 10031947532846003023 10031947532846003023 No MSc in Epidemiology, Guilan Road Trauma Research Center, Poursina Hospital, Guilan University of Medical Sciences, Guilan, Iran Shahrokh Yousefzadeh-Chabok شاهرخ یوسف زاده چابک 10031947532846003024 10031947532846003024 Yes MD, Professor of Neurosurgery, Guilan Road Trauma Research Center, Guilan University of Medical Sciences, Rasht, Guilan, Iran
