Transcript

  • 1. G  Ferretti     University  hospital  of  Grenoble,  France    
  • 2. ¡  Dyspnea  is  generally  defined  as  a  subjective   experience  of  breathing  discomfort   ¡  Equivalent:  breathlessness  or  shortness  of  breath   or  unpleasant  urge  to  breathe   ¡  Acute  vs.  chronic  if  >  1  month  in  duration   ¡  Dyspnea  is  one  of  the  most  frequent  symptoms  of   presentation  of  thoracic  diseases  in  the  ED  
  • 3. Dyspnea  may  be  of  neurogenic,  respiratory,  or  cardiac   origin,  and  may  be  associated  with  conditions  such  as   anemia,  deconditioning,  or  anxiety.   85%  of  all  cases  of  shortness  of  breath  are  caused  by:   ¡  congestive  heart  failure  and  myocardial  ischemia     ¡  asthma,  COPD,  interstitial  lung  disease,  pneumonia,   ¡  psychogenic  disorders     ▪  SARKAR  S  EVALUATION  OF  THE  DYSPNEIC  PATIENT  IN  THE  OFFICE.  PRIM  CARE.   2006;33(3):643–657   >  30%  of  cases  are  related  multifactorial  etiology     ▪  AMERICAN  COLLEGE  OF  RADIOLOGY.  ACR  APPROPRIATENESS  CRITERIA.  CHRONIC   DYSPNEA—SUSPECTED  PULMONARY  ORIGIN.  2012.

  • 6. Acute infectious pneumonia Left atelectasis
  • 7. ¡  The  cases  in  which  CXR  shows  evident  etiology   of  dyspnea  will  not  be  discussed  here     ¡  But  more  difficult  cases  will  be  presented  with   emphasize  on  the  role  of  CT   §  Chronic  presentation   §  Acute  presentation  
  • 8. §  FEV1  /  FVC    <  70%    post-­‐bronchodilator   §  Role  of  CT   §  Phenotyping  COPD   §  Search  for  complications   §  Selection  of  patient  before  treatment

  • 13. Sub acute Hypersensitivity Pneumonitis
  • 14. Tracheobronchomalacia (TBM) ●  characterized by increased compliance and excessive collapsibility of trachea and / or bronchi (acquired / congenital) ●  an important cause of chronic nonspecific pulmonary symptoms ●  identified in 1–10% of bronchoscopies (Nuutinen Ann Clin Res 1977) ●  but is an under diagnosed condition as it escapes detection on inspiratory CT
  • 15. 56 yo man, COPD Recent worsening of chronic dyspnea End inspiratory CT: sabersheath trachea End expiratory VCT: airway collapse < 50% Dynamic expiratory VCT shows expiratory airway collapse > 70% VCT shows bowing of posterior membranous TBM confirmed by bronchoscopy Inspiration End expi During expi
  • 16. High grade mucoepidermoid
  • 17. ¡  25  yo  female     ¡  Chronic  obstructive  disease   ¡  FEV1:  2.36L;  64%   ¡  FEV1  /  VC:  72%   ¡  Treatment  for  asthma  failed   ¡  Proposed  diagnostic:  complicated  asthma

  • 20. ¡  Dynamic  stenosis  of  the  LMB  due  to  the   compression  between  the  aorta  and  the   thoracic  spine    
  • 21. ¡  HRCT  is  the  most  sensitive  modality  for  diagnosing   early  emphysema  in  smokers  with  dyspnea.     ¡  HRCT  is  more  sensitive  than  pulmonary  function   tests  for  diagnosing  emphysema.   ¡  HRCT  phenotypes  BPCO   §  Emphysema   §  Diseases  of  the  airways   ¡    HRCT  helps  choosing  appropriate  treatment

  • 25. Possible NSIP in a patient with systemic sclerosis
  • 26. 83 yo man Dyspnea at exercise Worked as a dentist Silicosis complicated with emphysema
  • 27. ¡  HRCT  the  best  non  invasive  tool   ¡  particularly  appropriate  when  the  results  of  clinical,   radiographic,  and  laboratory  studies  are  either   nonrevealing  or  nondiagnostic.     ¡  Many  diseases  have  features  characteristic  enough   to  enable  experienced  radiologists  to  make  a   confident,  probable,  or  limited  differential  diagnosis   in  most  cases.   ¡  Thanks  to  HRCT,  biopsy  and  additional  diagnostic   testing  are  often  unnecessary.    
  • 28. ¡  Rarely  needed   ¡  Useful  in  diagnosing     §  Chronic  Thromboembolism  of  PA     §  fibrosing  mediastinitis   ¡  Is  recommended  in  case  of  mosaic  pattern   with  unremarkable  PFT.
