Introduction: Although still considered quite harmless, nonpowder guns (NPG) may cause severe head injuries in children. We present the case of a depressed skull fracture with superior sagittal sinus involvement following NPG injury. Decision-making and surgical management are discussed, and the current literature concerning NPG-related pediatric head injuries is reviewed., Case Presentation: A 4-year-old boy hit by a compressed-air rifle came to our center. CT scan showed a depressed skull fracture of the occipital bone on the midline and intracranial penetration of some fragments of the pellet. CT angiography documented a compression of the superior sagittal sinus without thrombosis. Soon after hospital admission, the patient showed deterioration of the neurological status suggesting intracranial hypertension. Surgery was performed with fracture elevation, removal of metal fragments, and wound debridement. The patient had a full recovery without subsequent neurological deficits., Discussion/conclusion: Modern airguns may produce severe penetrating head injuries in children. Parents and physicians should be aware of the danger of NPG. Depressed skull fracture and dural venous sinus involvement can occur, and even a stable neurological condition may worsen. In such instances, a thorough preoperative assessment including vascular imaging is mandatory. The surgical risk is not negligible due to the possible injury of the sinus wall and subsequent intraoperative bleeding. This has to be weighted against potential complications of the penetrating injury, such as infection, sinus thrombosis, and intracranial hypertension. Our case suggests that prompt surgical treatment can be a safe and effective option., (© 2021 S. Karger AG, Basel.)

Introduction: Cavernous malformations of the ventral brainstem are a challenging disease to treat. From an anatomical perspective, the best surgical options are endoscopic endonasal approaches. The first reports of their usage for this purpose date back to 2012. In this study, we gathered data on the subject, share our experience, and outline technical notes and tips for this surgery., Case Presentation: We report a 14-year-old female with a ventral pons cavernoma, treated using an endoscopic endonasal transclival approach and followed-up for 5.9 years. This is the longest reported follow-up for this condition to date. Written informed consent was obtained from the patient for publication of this case report and the accompanying images., Discussion: An endoscopic endonasal transclival approach was used. The skull base was reconstructed using the multilayer grafting technique and a nasoseptal flap. There was no postoperative cerebrospinal fluid leakage. In a literature review, we identified 8 patients who were treated endoscopically: 1 transplanum-transtuberculum, 1 transtuberculum-transclival, and 6 transclival approaches were employed. Skull base closure was achieved using multilayer grafting and a nasoseptal flap in 4 cases, a gasket seal technique combined with nasoseptal flap in 3 cases and a periumbilical fat graft, fibrin sealant patch, and fibrin glue in 1 case. There were 2 cases of leakage, which resolved completely with revision surgery., Conclusion: Endoscopic surgery is a reliable alternative to traditional open surgery. It may be the preferred choice for intra-axial ventral brain cavernomas., (© 2022 S. Karger AG, Basel.)

Introduction: Achondroplasia is a genetic disorder characterized by defects in the development of endochondral bone resulting in skeletal abnormalities like stenosis of the foramen magnum and of the spine, shortened limb bones, and macrocephaly. Congenital spinal stenosis is frequent and due to premature fusion of the pedicles to the laminae., Case Presentation: We report a case of neurogenic bladder and fecal incontinence due to lumbar stenosis successfully treated with L1-L5 partial laminectomy and foraminotomy in a 7-year-old achondroplasic child., Discussion/conclusion: To our knowledge, this is the first case report of exclusive neurogenic bladder and fecal incontinence in an achondroplasic child. Neurogenic bladder and fecal incontinence without motor impairment may be early and exclusive clinical findings of lumbar stenosis in children with achondroplasia., (© 2021 S. Karger AG, Basel.)

Background: Secondary endoscopic third ventriculostomy (ETV) for the management of shunt failure may be efficacious, though it may be followed by more frequent complications (including endocrinological impairment, e.g., amenorrhea) compared to primary ETV. These complications are usually underreported in the literature., Aim: We report a case of secondary amenorrhea after ETV for the management of shunt failure in a young woman with hydrocephalus associated with myelomeningocele., Methods: A 25-year-old woman affected by hydrocephalus and myelomeningocele was admitted for secondary ETV for the management of shunt failure. The endoscopic procedure was preferred over shunt revision based on good results of secondary ETV, especially in patients with hydrocephalus associated with Chiari II malformation and spina bifida., Results: Despite the surgery being uneventful, the patient had early (postoperative seizure) and late (secondary amenorrhea) complications. In the early postoperative period, she received external ventricular drainage followed by VP shunt reimplantation 2 weeks later. There was no neurological morbidity, but 1 month after the ETV she reported secondary amenorrhea and weight gain. Laboratory investigations ruled out hyperprolactinemia, which had been treated with cabergoline administration with no efficacy since the patient was still without regular periods 1 year later., Conclusion: ETV may be followed by endocrinological complications like amenorrhea that are rarely reported., (© 2015 S.

Gangliogliomas with anaplastic features are classified as grade III tumors by the World Health Organization. The clinical course and optimal treatment of anaplastic gangliogliomas have not been well understood to date. We report a case of a primary pure anaplastic ganglioglioma in a 14-year-old male treated with surgery and radiotherapy, who is disease-free 6 years after the diagnosis. A review of primary pure anaplastic gangliogliomas in children (between 3 and 21 years of age) is presented. Gross total removal and focal radiotherapy with a total dose of 54 Gy are recommended. The addition of chemotherapy should be evaluated. Prospective studies are needed to identify an appropriate chemotherapy schedule and to define biological factors in order to select those patients with a poor prognosis, who are to be treated with a more aggressive therapy., (Copyright © 2012 S.
