Transcript of "Thoracic imaging terms 2"

  1. 1. Terms for ThoracicImaging ..Unifying the language. Part II Dr/Ahmed Bahnassy Consultant Radiologist –RMH. MBCHB-MD-FRCR.
  2. 2. air crescent An air crescent is a collection of air in a crescentic shape that separates the wall of a cavity from an inner mass.It can represent aspergilloma on top of chronic cavity,partially ruptured hydatid cyst,or fungus ball in cavitary bronchiectasis.
  3. 3. apical capAn apical cap is a caplike lesion at the lung apex, usually causedby :intrapulmonary and pleural fibrosis(due to old TB)pulling down of extrapleural fatOr It can be due to superior sulcus tumour.
  4. 4. aortopulmonary windowThe aortopulmonary windowis the mediastinal region boundedanteriorly by the ascending aorta,Posteriorly by the descending aorta,Cranially by the aortic arch,inferiorly by the left pulmonary artery,medially by the ligamentum arteriosum,and laterally bythe pleura and left lung
  5. 5. silhouette signThe silhouette sign isthe absence of depiction of an anatomicsoft-tissue border. It is caused by consolidationand/or atelectasis of the adjacentlung
  6. 6. bronchiolectasisBronchiolectasis is defined as dilatation of bronchioles. It is caused by inflammatory airways disease (potentially reversible) .
  7. 7. beaded septum signThis sign consists of irregular and nodular thickening of interlobular septa reminiscent of a row of beads.Loaded interstitium by fluid or inflammatory ,or malignant cells should be thought (pulmonary edema,Interstitial pneumonias ,sarcoidosis,lymphangitis carcinomatosis)
  8. 8. ground-glass opacityarea of hazy increased lung opacity, usually extensive,within which margins of pulmonary vessels may be indistinct. On CT scans, it appears as hazy increased opacity of lung, with preservation of bronchial and vascular margins
  9. 9. halo signThe halo sign is a CT findingof ground-glass opacity surrounding a nodule or mass.DD: (1)invasive aspergillosis.
  10. 10. reversed halo signThe reversed halo sign is a focal rounded area of ground-glass opacity surrounded by a more or less complete ring of consolidation . A rare sign, it was initially reported to be specific for cryptogenic organizing pneumonia but was subsequently described in patients with paracoccidioidomycosis
  11. 11. honeycombingHoneycombing represents destroyed and fibrotic lung tissue containing numerous cystic airspaces with thick fibrous walls,representing the late stage of various lung diseases.The cysts range in size from a few millimeters to several centimeters in diameter,have variable wall thickness, andare lined by metaplastic bronchiolar epithelium
