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.

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.

Case Reports
MRI, CT, US and ERCP in the evaluation of bile duct hamartomas (von Meyenburg complex): a case report.
A case of multiple bile duct hamartomas (von Meyenburg complex) of the liver accompanied by exudative and in part necrotizing pancreatitis is presented. Magnetic resonance imaging (fat suppressed, T2-weighted images with prolonged echo time) could exclude diffuse tumor infiltration of the liver, which had not been possible with CT, sonography, or ERCP. To our knowledge, no comparable case has been reported.

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.

A right subclavian artery pseudoaneurysm caused by blunt trauma is described. CT and digital subtraction angiography helped us to establish a correct diagnosis. Radiologic features of subclavian artery aneurysms and relevant literature are briefly discussed.
