Lateral-type posterior fossa ependymomas in pediatric patients: a national collaborative study.

Purpose: To review a multicentric series of lateral-type posterior fossa ependymomas operated in the last ten years and to analyze the factors related to clinical evolution and tumor survival.

Methods: Descriptive, retrospective study. Active members of the Spanish Society of Pediatric Neurosurgery were invited to participate in this multicentric study.

Multicentric and collaborative study of Spanish neurosurgical management of pediatric craniopharyngiomas: S-PedCPG.co.

Purpose: To present a descriptive analysis of pediatric craniopharyngiomas (PedCPG) treated in various Spanish hospitals, defining factors related to recurrence and performing a critical analysis of the results.

Methods: We undertook a multicenter retrospective review of PedCPG treated between 2000 and 2017. Data collected included epidemiological variables, clinical and radiological characteristics, goal of first surgery, rate of recurrence and its approach, adjuvant treatment, complications and permanent morbidity.

Pleural effusion in a child with a correctly placed ventricle-peritoneal shunt.

Pleural effusions in children (PE) due to ventricle-peritoneal shunt (VPS) is very rare, with few cases reported. We present a new case of an infant with VPS who had a massive hydrothorax not associated with misplacement or migration of the distal catheter or with ascites. After the evacuation of the PE we managed the patient by adjusting the pressure of the adjustable valve (AV).

[Fluorescence-guided resection with 5-aminolevulinic acid of an intramedullary tumor].

Fluorescence-guided resection with 5-aminolevulinic acid (5-ALA) has demonstrated its usefulness in the resection of malignant cerebral gliomas. It also seems useful for the treatment of other types of cerebral and intramedullary neoplasms. We present the case of a patient with an intramedullary tumor in who fluorescence- guided resection was useful for intraoperative localization, definition of small tumor nodules and in order to achieve a complete resection of the tumor.
