Comparative Study
MR imaging of uterine cervical carcinoma: comparison between fast spin-echo MRI and GRASE.
The aim of our study was to compare the image quality of T2-weighted gradient-echo-and-spin-echo (GRASE) MRI and fast spin-echo (FSE) MRI for imaging of cervical carcinoma. In 40 patients FSE8 (TR/TE = 3400/90 ms) MRI with echo train length (ETL) of 8, GRASE (3400/90) MRI with ETL of 18, turbo factor of 6 and 3 gradient reversals, and FSE18 (2500/120) MRI with ETL of 18 were performed. Tissue contrast, subjectively rated image quality, and accuracy of tumor delineation were compared. ⋯ The accuracy of FSE and GRASE MRI for the delineation of cervical carcinoma is similar. Based on measurement of image quality and CNRs, however, high turbo factor FSE provides better image quality in MRI of cervical carcinoma. Whether the superior characteristics may result in better staging has to be explored in larger clinical trials.

We report on two patients with biliary tract injury and associated biloma following blunt abdominal trauma. Both patients underwent emergency surgery because of hemodynamic instability and bloody peritoneal aspiration. ⋯ Bile duct injury was well demonstrated on endoscopic retrograde cholangiography (ERCP) and treated by endobiliary stent placement. This report advocates the use of ERCP and endobiliary stenting in the management of biliary injury resulting from liver trauma.

Paget's disease is a common entity but osteosarcoma arising in Paget's disease is an infrequent complication. Primary osteosarcomas are typically long bone tumours and the skull is rarely affected. ⋯ Computed tomography scans of the tumour area show interesting results. Main features are: an intensive sclerotic reaction of the host bone, an inner and outer spiculation of the calvarium, radial ossifications in the soft extracranial mass, and spotty calcifications and ossifications of the osteosarcomatous portion infiltrating the brain.

A 69-year-old diabetic male with salmonella bacteremia developed hypovolemic shock and swelling of the neck. A CT examination revealed massive mediastinal hemorrhage extending into the neck soft tissues caused by false aneurysm rupture of the descending thoracic aorta. ⋯ Although surgical intervention was immediately performed, the patient died 3 weeks later from multiple-organ failure. In this report, CT and angiographic findings of mycotic aneurysm rupture are presented and a review is given.

Primary pulmonary amyloidosis is a rare disorder that appears in three forms: tracheobronchial, nodular parenchymal, and diffuse parenchymal. We report the case of a 46-year-old women with extensive tracheobronchial amyloidosis which presented with a 2-year history of dyspnea and with signs of severe fixed obstruction in pulmonary function tests. ⋯ Transbronchial specimen showed typical birefringence under polarizing microscope after staining with Congo Red. We did not find hints for systemic amyloidosis.
