The current study concluded that:• Ultrasound had high sensitivity and moderate diagnostic accuracy in evaluating abdominal wall masses. • Ultrasound may limit the patient's exposure to invasive biopsies and to the hazardous exposure to ionizing radiation and contrast media administration like that in the CT examination.

Local injection of steroids is efficient in the treatment of carpal tunnel syndrome with proved superiority of the ultrasoundguided approach.We enrolled 30 patients with mild or moderate carpal tunnel syndrome. 15 patients were injection blindly and 15 patients were injected under ultrasound guidance. We used a combination of triamcinolone and lidocaine. Non-guided injection was performed with identification of the tendon of the palmaris longus muscle, then insertion of the needle just ulnar to it. Guided injection was conducted with sonographic recognition of the carpal tunnel contents; flexor retinaculum, median nerve and flexor tendons. This is followed by introduction of the needle at the medial side of the ultrasound probe, then injecting the steroid in the carpal tunnel. Evaluation was accomplished by clinical and sonographic analysis. Initial assessment was performed before the procedure and follow-up was carried out four weeks later. The acquired values were compared to each other and tabulated.
