Lumbar safety triangle: comparative study of coronal and coronal oblique planes in 3.0-T magnetic resonance imaging.

Objective: To compare the measurements of the lumbar safety triangle (Kambin's triangle) and the invasion of the dorsal root ganglion in the triangle in coronal and coronal oblique planes.

Materials And Methods: A cross-sectional study, in which 210 3.0-T magnetic resonance images of L2-L5 were analyzed in coronal and coronal oblique planes.

Aggressive Diffuse Intraosseous Hemangioma: Case Report.

Vertebral hemangioma is a benign vascular tumor that is usually asymptomatic and is discovered incidentally on imaging. When symptomatic, the most frequent presentation occurs in the form of vague back pain of insidious onset and, in rare cases, may be associated with root or spinal compression, causing sensory and motor deficits. The authors report the case of a 33-year-old man, previously healthy, with a diagnosis of thoracic spine hemangioma at multiple levels, in the sternum, in the scapula and in the costal arches; all lesions were symptomatic, and surgical intervention was required; one of the lesions at the thoracic spine level evolved with spinal compression and acute neurological deficit, requiring urgent surgical intervention.

Elevated cell-free plasma DNA level as an independent predictor of mortality in patients with severe traumatic brain injury.

Trauma is the leading cause of death in individuals less than 45 years old worldwide, and up to 50% of trauma fatalities are because of brain injury. Prediction of outcome is one of the major problems associated with severe traumatic brain injury (TBI), and research efforts have focused on the investigation of biomarkers with prognostic value after TBI. Therefore, our aim was to investigate whether cell-free DNA concentrations correlated to short-term primary outcome (survival or death) and Glasgow Coma Scale (GCS) scores after severe TBI.
