Intraosseous cranial arteriovenous malformations are extremely unusual and difficult to detect. The 12-year-old boy was born with a right scalp lesion that has accelerated growth for the past few months. Multiple intricate arterial feeders were discovered in a large, right parietoeccipital intraosseous AVM with multiple complex arterial feeders, according to digital subtraction angiography. The authors explore what is believed to be the second case of an AVM originating in the cranial bones and the first case with successful multidisciplinary leadership.

The authors explore the case of a patient with the classic clinical appearance and radiographic signs of a nasal dermal sinus with an associated intracranial cyst; however, histopathology revealed that the intracranial cyst was neurenteric rather than the typical epidermoid or dermoid cyst.

OBJECTIVE Hydrocephalus with subdural hygromas is a rare complication after decompression of Chiari malformation type I. The authors present a collection of 5 pediatric patients who underwent CM-I decompression after the placement of a dural graft complicated by posterior fossa hygromas and hydrocephalus that were successfully controlled nonoperatively. paraphrasedoutput:METHODS is a nonprofit organization that provides a retrospective review of patients with hydrocephalus and subdural hygromas following foramen magnum decompression with the insertion of a dural graft for CM-I. Five pediatric patients with a delayed postoperative complication involving hydrocephalus and subdural hygromas were identified in five cases, including subdural hygromas and delayed postoperative complication. This presentation shows that these complications following posterior fossa decompression with duraplasty can be managed with nonoperative medical care, thus eliminating the need for CSF diversion or reoperation.

The choroid plexus' villous hyperplasia is a rare symptom of communicating hydrocephalus. DVHCP can be diagnosed both radiographically and through histological analysis. Patients with DVHCP often fail to handle shunting alone, and may require adjuvant interventions. The authors explore the case of a child with partial trisomy 9p and delayed diagnosis of hydrocephalus with radiographic evidence of DVHCP's success with ventriculoperitoneal shunt placement, adjuvant bilateral endoscopic plexus coagulation, and the first use of anterior choroidal artery embolization. A 14-month-old girl with partial trisomy 9p was presented with macrocephaly and radiographic evidence of interacting hydrocephalus and DVHCP. Ventriculoperitoneal shunting resulted in distal failure due to inadequate CSF absorption, but ventriculopulmonary shunt placement was not possible due to several cardiac anomalies. Production was reduced by endoscopic third ventriculostomy and bilateral CPC, followed by distal choroidal embolization, which enabled VPS re-internalization. In the literature, thirteen pediatric, three adult, and two postmortem have been identified. DVHCP is a rare occurrence of communicating hydrocephalus that can be attributed to genetic abnormalities. The present case demonstrates that angiographic evidence of prominent choroidal arteries can aid in the diagnosis DVHCP. In addition, embolization of the distal choroidal arteries may be considered as a potential adjuvant therapy in patients for whom traditional medical procedures have failed or are not appropriate.

Pedicle aplasia is unusual congenital anomaly, most commonly involving the absence of a single pedicle at a single vertebral level. Though single-level pedicle aplasia is usually asymptomatic and found in the wrong context, multiple levels of pedicle aplasia can cause serious spinal deformities and neurological abnormalities.

The authors conducted a retrospective review of our pediatric CBT patients and screening for CBT patients with evidence of a CBT over the past ten years at a single tertiary referral pediatric hospital in the United Kingdom. They conducted a systematic analysis of all reported cases of pediatric CBTs to determine the characteristics, treatment paradigms, and complications, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Palpable neck mass, cranial nerve palsies, cough or dysphagia, and neck pain were the most common presenting signs. Only 10% of patients were diagnosed with elevated catecholamines and a strong emotional involvement. CONCLUSIONS OBSUMENTS CONCLUSIONS CBT surgical management of CBTs necessitates extensive preoperative investigation, anesthesia, and multimodal surgical care. balloon test occlusion with embolization in select patients prior to resection may be required due to a potentially high rate of surgical morbidity and vascularity.

Although spinal epidural arteriovenous malformations, fistulas, and shunts have been well documented, the presence of a venous malformation in the spinal epidural space is a rare occurrence. Herein, the authors discuss the clinical presentation, imaging results, pathological characteristics, and the results of surgical and percutaneous interventional therapy of a mediastinal and spinal epidural venous malformation in a young woman who presented clinically with neurogenic claudication in the onset of a syrinx.
