title: Angiosarcoma in the chest: radiologic-pathologic correlation: Case report.
abstract: BACKGROUND
  Angiosarcomas are rare, malignant vascular tumors.
  
  
  METHODS
  They represents about 2% of all soft tissue sarcoma, which can often metastasize through the hematogenous route. The radiological features have been analyzed in 4 patients with metastatic angiosarcoma in the chest.
  
  
  METHODS
  The main radiologic findings included nodules, cysts, nodules with halo sign, and vascular tree-in-bud. Morphologic features, as observed in the histologic specimen, have been correlated with radiologic appearance.
  
  
  CONCLUSIONS
  Metastatic angiosarcomas to the lung are characterized by a wide variety of radiologic appearances that can be very characteristic. Computed tomographic findings observed include bilateral solid nodules, cystic, and bullous lesions sometimes associated with spontaneous hemopneumothoraces.
