In the article, “Pedunculated intraventricular subependymoma: Review of the literature and illustration of classical presentation through a clinical case”, which appeared in the article number 117, Issue 1, Vol 5 of Surgical Neurology International[1], the acknowledgement section is missing. The acknowledgement section will be as follows:“The authors would like to thank Dr. Fernando Alvarado-Calderón, MD, pathologist at the Hospital Calderón Guardia, for his invaluable help in providing the definite histologic diagnosis and the corresponding images for this case.”This has now been corrected and reposted online.
