Spinal intradural arachnoid cysts are rare with only a few patients reported so far. Idiopathic, traumatic, posthemorrhagic, and postinflammatory causes have been reported in the literature. Especially, idiopathic lesions, in which other possible etiological factors have been ruled out, seem to be rare. ⋯ Idiopathic spinal intradural arachnoid cysts can present with neurological deficits in children. Pathologies are predominantly located in the cervical spine anteriorly and in thoracic and thoracolumbar segments posteriorly to the spinal cord. In symptomatic cases, microsurgical excision and cyst wall fenestration via laminotomy are recommended. Our radiological, intraoperative, and pathological findings support the cerebrospinal fluid obstruction and vent mechanism theory of arachnoid cysts.

Current Brain Trauma Foundation guidelines recommend avoiding hypoxemia after severe pediatric traumatic brain injury (TBI). Yet, recent studies on optimum admission oxygenation and ventilation parameters associated with discharge survival in pediatric TBI are lacking. ⋯ Discharge survival after severe pediatric TBI was associated with admission PaO2 301-500 mmHg and PaCO2 = 36-45 mmHg. Admission hypocarbia and hypercarbia were each associated with increased discharge mortality.

Aplasia cutis is a rare developmental anomaly usually involving the calvarium, associated with a variable extent of defective formation of the scalp. Adams-Oliver syndrome is a condition mainly characterized by the congenital absence of skin, known as "aplasia cutis" which is usually limited to the vertex scalp and transverse limb defects. ⋯ Aplasia cutis is a rare developmental anomaly usually involving the calvarium, associated with defective formation of the scalp to a varying extent and severity, requiring various timely strategies.
