title: Benign localized fibrous tumour of the pleura: CT features with histopathological correlations.
abstract: OBJECTIVE
  To assess the CT features of benign localized fibrous tumour of the pleura, with histopathological correlations.
  
  
  METHODS
  CT and histopathological findings of 18 patients with surgically resected benign localized fibrous tumour of the pleura were retrospectively assessed.
  
  
  RESULTS
  Tumours were pleura or fissure based, semilunar, lentiform or oval in shape, classified according to their homogeneous, slightly heterogeneous or heterogeneous enhancement pattern. Of the 18 tumours, 5 (28%) demonstrated > or = 55 HU increment or higher attenuation than muscles on contrast-enhanced CT, and histopathologically showed a haemangiopericytoma-like pattern with rich vascularity.
  
  
  CONCLUSIONS
  CT analysis of the shape of a mass and the enhancement pattern can be helpful in the diagnosis of benign localized fibrous tumour of the pleura.
