Clinical Characteristics of Benign Pediatric Cranial Vault Tumors: Surgical Considerations Based on 100 Cases
Conclusions: Cranial vault tumors are characterized by constant growth and may penetrate the cranial cavity. Delayed surgery increases the risk of intracranial complications. Surgical problems include inappropriate planning, higher risk of intraoperative bleeding, and the need for subsequent cranioplasty.Pediatr Neurosurg (Source: Pediatric Neurosurgery)

Spontaneous Resolution of Spinal Epidural Hematoma Resulting from Domestic Child Abuse: Case Report
Nonaccidental head injury, as seen in domestic child abuse cases, is often associated with spinal injury, and spinal subdural hematoma is the most frequent diagnosis. While spinal epidural hematomas are a rare occurrence, the incidence of spontaneous epidural hematomas occurring in nonaccidental head injury patients is even lower. Epidural hematomas often result in acute focal neurological deficits necessitating emergent neurosurgical intervention. In patients without focal neurological deficits, conservative management may allow for spontaneous resolution of the epidural hematoma. The authors present the case of a 2-year-...

Eosinophilic Granuloma of Skull with Fluid Level and Epidural Hematoma: A Case Report and Review of the Literature
We report a 15-year-old boy who presented with a spontaneous epidural hematoma which was the result of a temporal eosinophilic granuloma. Multiple explanations for epidural hematoma in such cases have been discussed. Intratumoral hemorrhage followed by cyst formation and rupture may explain the pathophysiology of epidural hemorrhage formation.Pediatr Neurosurg (Source: Pediatric Neurosurgery)

Giant Interfrontal Encephalocele in an Infant: A Rare Entity
Interfrontal encephalocele is one of the rare varieties of anterior encephalocele, and a giant interfrontal encephalocele is extremely rare. The authors could find only one case report of giant interfrontal encephalocele in the literature. Anterior encephaloceles are more prevalent in South-East Asia and some northern parts of India. Giant encephalocele poses a great challenge to neurosurgeons and neuroanesthetists during surgery, as these infants usually have a low birth weight and a large sac, thus making the infant prone to hypothermia and blood loss among other risks. We encountered a patient with a giant interfrontal ...

Magnetically Controlled Growing Rod in Early-Onset Scoliosis: A Minimum of 2-Year Follow-Up
Conclusions: The magnetically controlled growing rod is beneficial in early-onset scoliosis, since it enables spinal growth and decreases additional surgeries, complications, and costs.

Foot drop is an inability to dorsiflex the ankle and toe. Primary causes of foot drop are compression or lesion of the 5th lumbar nerve and entrapment of the peroneal nerve at the head of the fibula. Rarely, some central nervous system lesions lead to foot drop. A 16-year-old boy was admitted with blunt head trauma that had happened in an assault.

We calculated the sensitivity, specificity, negative predictive value (NPV) and positive predictive value of the CDRs-PECARN in 2 age groups. Sensitivity was very high in both groups, and the NPV was very useful for predicting which subjects, of those who presented without CDRs- PECARN, would have a negative cranial CT. We also evaluated the correlations between the GOS-E Peds and Glasgow Coma Scale and between the GOS-E Peds and cranial CT scan. Our study confirms the validati...

Retroclival Pneumocephalus Associated with Bilateral Abducens Palsy in a Child
Traumatic brain injury (TBI) is less common in children than in adults. Posterior fossa lesions are even more uncommon, but, when present, are usually epidural hematomas. These lesions, even when small, may have a bad outcome because of the possibility of compression of the important structures that the infratentorial compartment contains, such as the brainstem and cranial nerves, and the constriction of the fourth ventricle, causing acute hydrocephalus. Although unusual, posterior fossa lesions are increasingly being diagnosed because of the better quality of and easier access to cranial tomography. In this paper, we repo...
