Non-contrast computerized tomography (NCCT) and dynamic renal scintigraphy (DRS) in the patients with refractory renal colic.

Objectives: To assess the importance of combined use of non-contrast computerized tomography (NCCT) and dynamic renal scintigraphy (DRS) in evaluation of patients with refractory flank pain in the emergency department.

Methods: The study involved 64 consecutive patients with refractory renal colic. All patients were evaluated with plain abdominal films kidneys, ureters and bladder (KUB), NCCT and DRS.

Color Doppler sonography: its real role in the evaluation of children with highly suspected testicular torsion.

The goal of this study was to assess the reliability of color Doppler imaging in boys who presented with acute scrotal pain and borderline clinical findings. The second purpose of the study was to evaluate the potential change in diagnostic accuracy as a result of employing radiological staff with varying levels of experience. Thirty-eight consecutive patients with highly suspected testicular torsion were enrolled in this prospective study.

Early antibiotic treatment may prevent complete development of Lemierre's syndrome: experience from 2 cases.

Lemierre's syndrome is a rare fulminant condition caused by an acute oropharyngeal infection, with secondary septic thrombophlebitis of the internal jugular vein complicated by multiple metastatic infections. Herein we report 2 patients with internal jugular vein thrombosis secondary to oropharyngeal infection, whose clinical course was indolent, and who were asymptomatic shortly after antibiotic therapy was begun. Careful examination of the neck in patients presenting with sore throat could help identify the typical 'cord sign'.

Huge renal arteriovenous malformation mimicking a simple para-pelvic cyst.

The presenting symptoms of renal arteriovenous malformation are usually gross hematuria and hypertension. Herein we present an unusual case of a huge renal arteriovenous malformation without these signs, but with an ultrasound picture mimicking a simple para-pelvic cyst. Other imaging tests, including duplex ultrasound, computerized tomography and aortography, demonstrated the vascular lesion.
