title: Semi-invasive pulmonary aspergillosis in an immunosuppressed patient: a case report.
abstract: BACKGROUND
  The authors present the high-resolution computed tomography findings of an immunosuppressed patient with semi-invasive pulmonary aspergillosis.
  
  
  METHODS
  The main finding consisted of irregular, thick-walled cavity in the right upper lobe and a mass with soft-tissue attenuation within it and thickening of adjacent pleura. Additional findings were bronchial wall thickening associated with a 'tree-in-bud' pattern. Following the clinical, laboratorial and imaging criteria, the diagnosis of semi-invasive pulmonary aspergillosis was defined and antifungical treatment was introduced.
  
  
  CONCLUSIONS
  The patient responded well to the treatment with improvement in his systemic symptoms and regression of the pulmonary lesions.
