Traumatic subaxial cervical facet subluxation and dislocation: epidemiology, radiographic analyses, and risk factors for spinal cord injury.

Background Context: Distractive flexion injuries (DFIs) of the subaxial cervical spine are major contributors to spinal cord injury (SCI). Prompt assessment and early intervention of DFIs associated with SCI are crucial to optimize patient outcome; however, neurologic examination of patients with subaxial cervical injury is often difficult, as patients commonly present with reduced levels of consciousness. Therefore, it is important to establish potential associations between injury epidemiology and radiographic features, and neurologic involvement.

Adult supratentorial primitive neuroectodermal tumour presenting as intracranial haemorrhage: Case report.

Primitive neuroectodermal tumours (PNET) are highly malignant tumours with an aggressive clinical behaviour. Commonly seen in children, they are uncommon in the adult population, and rare in the supratentorial location. Adult supratentorial PNETs (ST-PNET) typically present with symptoms relating to raised intracranial pressure, seizures, or focal neurological deficits.

Detecting Facet Joint and Lateral Mass Injuries of the Subaxial Cervical Spine in Major Trauma Patients.

Study Design: Radiologic imaging measurement study.

Purpose: To assess the accuracy of detecting lateral mass and facet joint injuries of the subaxial cervical spine on plain radiographs using computed tomography (CT) scan images as a reference standard; and the integrity of morphological landmarks of the lateral mass and facet joints of the subaxial cervical spine.

Overview Of Literature: Injuries of lateral mass and facet joints potentially lead to an unstable subaxial cervical spine and concomitant neurological sequelae.

Lumbosacral epidural lipomatosis causing rapid onset cauda equina syndrome.

Spinal epidural lipomatosis (SEL) is a rare cause of cauda equina syndrome (CES), which must be diagnosed with MRI in conjunction with a high level of clinical suspicion. Most reported cases are associated with obesity, steroid use or are secondary to endocrinopathies, frequently present subacutely or chronically, and have been managed with both surgical decompression and non-operative measures. We describe an obese 55-year-old man with rapid onset CES secondary to idiopathic lumbosacral SEL which was managed successfully with surgical decompression.

Clinical applications of biomarkers in pediatric traumatic brain injury.

Introduction: The diagnosis, treatment, and prediction of outcome in pediatric traumatic brain injury (TBI) present significant challenges to the treating clinician. Clinical and radiological tools for assessing injury severity and predicting outcome, in particular, lack sensitivity and specificity. In patients with mild TBI, often there is uncertainty about which patients should undergo radiological imaging and who is at risk for long term neurological sequelae.
