Incidental thyroid lesions identified by ultrasound in patients with non-thyroidal head and neck cancer.

Background: Thyroid cancer is one of the common head and neck malignancies and may be found incidentally with other head and neck cancers.

Purpose: To evaluate the prevalence and risk of malignancy in incidental thyroid lesions identified by ultrasound (US) in patients with head and neck cancer.

Material And Methods: We retrospectively reviewed medical records of all patients with head and neck cancer other than of thyroid origin between January 2004 and December 2011.

Diagnostic accuracy of hepatic venous pressure gradient measurement in the prediction of stage 1 compensated liver cirrhosis in patients with chronic hepatitis B.

Objective: Hepatic venous pressure gradient (HVPG) of 6-10 mmHg has been accepted as a hemodynamic parameter of stage 1 compensated liver cirrhosis (LC). The diagnostic accuracy of HVPG in the prediction of stage 1 compensated LC has been investigated in patients with chronic hepatitis B (CHB).

Methods: A total of 219 patients with CHB who underwent HVPG and liver biopsy were enrolled.

Superparamagnetic iron oxide (SPIO)-enhanced liver MRI with ferucarbotran: efficacy for characterization of focal liver lesions.

Purpose: To evaluate the efficacy of ferucarbotran in T2-weighted (T2W) fast spin-echo (FSE) and T2*W gradient-echo (GRE) sequences for characterizing focal liver lesions.

Materials And Methods: In 68 patients, 46 malignant and 22 benign focal liver lesions were evaluated. Precontrast (NCE) T2W FSE images and contrast-enhanced (CE) T2W FSE and T2*W GRE images were obtained on a 1.

Low-dose and standard-dose unenhanced helical computed tomography for the assessment of acute renal colic: prospective comparative study.

Purpose: To compare the efficacy of low-dose and standard-dose computed tomography (CT) for the diagnosis of ureteral stones.

Material And Methods: Unenhanced helical CT was performed with both a standard dose (260 mAs, pitch 1.5) and a low dose (50 mAs, pitch 1.

Perforated ileal duplication cyst with haemorrhagic pseudocyst formation.

Duplication cysts of the gastrointestinal tract are rare congenital abnormalities. Ectopic gastric mucosa, which can be found in duplications, may cause peptic ulceration, gastrointestinal bleeding or perforation. We report a 1-year-old boy with a perforated ileal duplication cyst with haemorrhagic pseudocyst formation caused by peptic ulceration of the duplication cyst.
