Case ReportsThe thoracic spine sign in bedside ultrasound. Three cases report.
The "thoracic spine sign" is visualized when anechoic or hypoechoic fluid is present in the pleural space. Fluid serves as a medium through which the thoracic vertebral bodies are visualized above the diaphragm. ⋯ These patients were subsequently diagnosed with pleural fluid accumulations on chest radiograph. Our findings suggest that the identification of the sonographic spine sign may aid the physician in the evaluation and diagnosis of emergency department patients with thoracic complaints.

Review Comparative StudySurgical hepatic resection vs. ultrasonographic guided radiofrequency ablation in colorectal liver metastases: what should we choose?
Clinical evolution of the colorectal carcinoma occurs in up to 60% with colorectal liver metastases (CRLM). Although hepatic resection is considered to be the golden standard in CRLM, novel less invasive techniques have emerged, of which radiofrequency ablation has received a high credibility. ⋯ While open surgery guarantees a more precise tumor excision, the effectiveness of ablation must be evaluated either by contrast-enhanced computer tomography, magnetic resonance, or ultrasound. This paper aim to review the current standings in radiofrequency ablation for CRLM and to compare the technique with surgical resection in order to find which one is the best treatment option.
