Abstract
AIM: To assess the CT features of benign localized fibrous tumour of the pleura, with histopathological correlations. MATERIALS AND 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. CONCLUSION: 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.
