Choroid plexus papilloma is a low-frequency entity in both the adult and pediatric populations. Its clinical presentation is very variable as it depends on its location and length. We must always do the differential diagnosis between papilloma and other intraventricular pathologies. This article is about a case report of a pediatric patient with a Choroid plexus papilloma located in the fourth ventricle, a location that is atypical for the pediatric population.

Background: Spinal fractures are becoming more frequent and should be handled as a severe and endemic pathology that requires timely diagnosis and adequate treatment. The classification of the AOSpine is currently the classification used for this type of fractures, not only for its approach, but to predict surgical management.Methods: These patients had spinal fracture reduction procedures done through percutaneous way with expander endovertebral implants, and intraosseous fixation using SpineJack ® intravertebral implants plus Cohesion ® cement. Within the follow-up scheme, subsequent measurements were taken after a week, a month after surgery, 3 months after the procedure and after 6 months of follow-up. STATA ® (Statistical Analysis System, version 12.1, SAS Institute Inc., Cary, NC, USA) was used for all analyzes. The Wilcoxon or Student's t-test was used for comparisons in pairs depending on the normality of the distribution.Results: A clinical follow-up is performed to 20 consecutive patients experiencing spinal compression fractures (SCF) who received percutaneous treatment involving SpineJack ® and Cohesion ® cement, resulting in a statistically significant decrease of both pain and pain-related disability. No complications arose from the procedure.Conclusions: According to the observations, which reflect what is found in the world literature, this is an effective and safe way of handling SCF.

The dermal sinus tract of the spine is associated with other occult spinal dysraphisms, such as the split cord malformation (diastematomyelia) in a 40% of the cases and embryologically is not clearly defined if the dermal sinus and split cord malformation have origin in gastrulation or late primary neurulation, but the most accepted theory of the dermal sinus tract consists in early incomplete disjunction, which explains the relation with other spinal dysraphisms. Here, we present two cases, with a dermal sinus tract of the spine associated with Type I and Type II split cord malformation.
