A 44-year old man presented with increased shortness of breath. A chest X-ray revealed a widening of the mediastinum (Fig. 1a). Magnetic resonance imaging demonstrated a right paratracheal tumour (Fig. 1b, c). Rotational arteriography showed that the right thyrocervical artery was supplying the mass (Fig. 1d). He underwent a right cervical incision and thoracotomy resection of the mass. Histolo...

RATIONALE A foregut duplication cyst (FDC) is an uncommon congenital disease. This report presents a case of mediastinal foregut duplication cyst that mimicked a diaphragmatic small bowel hernia. PATIENT CONCERN A 27-month-old girl was first referred for a mediastinal lesion found incidentally on a chest radiograph. At that time, our impression was cystic lung lesion such as congenital pulmon...

PURPOSE We retrospectively reviewed the CT findings in 24 cases of autosomal dominant polycystic kidney disease (ADPKD) to assess the role of CT in the diagnostic work-up of patients with complicated ADPKD. MATERIAL AND METHODS Twenty-four patients with ADPKD underwent unenhanced and contrast-enhanced CT for flank pain, haematuria, or fever. The images were retrospectively reviewed for presen...

azygos vein aneurysm is a rare cause of a posterior or paratracheal mediastinal mass. trauma or conditions causing elevated flow or pressure in the azygos system, such as cardiac failure or cirrhosis of the liver are secondary causes of aneurysm of the azygos vein. we report a case of asymptomatic saccular aneurysm of the azygos vein in a 45-year-old man with blunt minor chest trauma. the azygos...

exertional dyspnea, shortness of breath and a dry cough. Clinical examination revealed signs of a leftsided pleural effusion. Chest-wall expansion and basal air entry were reduced; percussion over the lower chest produced a dull note. A posteroanterior chest film demonstrated a left pericardial mass (Fig. 1, arrows). Computed tomography of the chest disclosed an extracardiac mass filled with fl...

BACKGROUND Malignancies located in the upper middle mediastinum usually do not have a sufficiently large acoustic window to permit a conventional ultrasound guided parasternal biopsy. This study was concerned with an alternative approach whereby ultrasound is applied through the supraclavicular paratracheal window to allow percutaneous biopsy of middle mediastinal malignancies. METHODS Fiftee...
