Pediatric colloid cysts: a multinational, multicenter study. An IFNE-ISPN-ESPN collaboration

OBJECTIVE Colloid cysts (CCs) are rare at all ages, and particularly among children. The current literature on pediatric CC is limited, and often included in mixed adult/pediatric series. The goal of this multinational, multicenter study was to combine forces among centers and investigate the clinical course of pediatric CCs. METHODS A multinational, multicenter retrospective study was performed to attain a large sample size, focusing on CC diagnosis in patients younger than 18 years of age. Collected data included clinical presentation, radiological characteristics, treatment, and outcome. RESULTS One hundred thirty-four children with CCs were included. Patient age at diagnosis ranged from 2.4 to 18 years (mean 12.8 ± 3.4 years, median 13.2 years, interquartile range 10.3–15.4 years; 22% were \u3c 10 years of age). Twenty-two cases (16%) were diagnosed incidentally, including 48% of those younger than 10 years of age. Most of the other patients had symptoms related to increased intracranial pressure and hydrocephalus. The average follow-up duration for the entire group was 49.5 ± 45.8 months. Fifty-nine patients were initially followed, of whom 28 were eventually operated on at a mean of 19 ± 32 months later due to cyst growth, increasing hydrocephalus, and/or new symptoms. There was a clear correlation between larger cysts and symptomatology, acuteness of symptoms, hydrocephalus, and need for surgery. Older age was also associated with the need for surgery. One hundred three children (77%) underwent cyst resection, 60% using a purely endoscopic approach. There was 1 death related to acute hydrocephalus at presentation. Ten percent of operated patients had some form of complication, and 7.7% of operated cases required a shunt at some point during follow-up. Functional outcome was good; however, the need for immediate surgery was associated with educational limitations. Twenty operated cases (20%) experienced a recurrence of their CC at a mean of 38 ± 46 months after the primary surgery. The CC recurrence rate was 24% following endoscopic resection and 15% following open resections (p = 0.28). CONCLUSIONS CCs may present in all pediatric age groups, although most that are symptomatic present after the age of 10 years. Incidentally discovered cysts should be closely followed, as many may grow, leading to hydrocephalus and other new symptoms. Presentation of CC may be acute and may cause life-threatening conditions related to hydrocephalus, necessitating urgent treatment. The outcome of treated children with CCs is favorable

Cerebrospinal fluid leak after combat penetrating gunshot wound to the head

Introduction: Cerebrospinal fluid leak is a common complication after head gunshot wounds, which commonly leads to infectious complications. This complication may prolong hospital staying and prevents soldiers from return to operation theatre as soon as possible.  The purpose of this article is to determine the impact of the quality of primary surgical debridement and other factors that influenced the presence of cerebrospinal fluid leak in the military stuff with gunshot wounds to the head.  Materials and methods: This is a retrospective study of 20 military cases with cerebrospinal fluid leak, which were admitted during the combat actions in Eastern Ukraine in the period from March 2014 to the end of December 2017. Information was collected on demographics, evacuation assistance, type of injury and infectious complications. R commander version 4.2.0 (http://www.r-project.org) was used for statistical analysis. Statistical significance was defined as p<0.05. Results: Cerebrospinal fluid fistulas were detected in 20 cases (25,31%). Factors affecting the rate of leaks are number of re-operations (p<0.001), multiple sites of injury (p=0.002), ventricular injury (p<0.005). CSF leakage significantly lengthens hospitalization time. Conclusions: CSF fistula influenced significantly rate of infection complication. Reoperation should follow initial surgery in cases of CSF leak development. To avoid development of cerebrospinal fluid fistulas, the operation should be performed by neurosurgeons in specialized department.&nbsp
