BACKGROUND: The aim of this study was to settle signs of benign pleural disease using computed tomography (CT) with medium of contrast and to value correlation of these signs with video-assisted thoracoscopic surgery (VATS) diagnosis, in order to limit this invasive procedure.
METHODS: Retrospective study of a single diagnostic center (San Luigi Gonzaga Hospital, Orbassano, Turin, Italy). We selected 39 patients from 2014 to 2017 who underwent a VATS procedure with diagnosis of benign pleural disease. Subsequently we related bioptic data with CT imaging.
RESULTS: Regarding to CT exam, 49% of patients did not have pleural thickening; 38% had evidence of pleural thickening <10 mm; 13% >10 mm. Concerning to location of thickening, it was in 39% of patients parietal, in 36% diaphragmatic, in 21% mediastinal. Appearance of thickening was, in majority of patients, smooth (39%); nodular in 28%. We observed a correlation with pleural effusion (95%), more often bilateral or right (both 41%). 21% of patients showed subpleural fat tissue enhancement after administration of contrast. Regarding to VATS examination, only 26% of patients showed pleural thickenings. These finds were in most cases smooth (64%) and parietal (74%). Only 26% and 10% were respectively diaphragmatic and mediastinal.
CONCLUSIONS: Scientific literature has today put particular attention only to malignant CT signs of pleural pathology. Even though our limited number of patients, we can conclude that, in benign pleural disease, some signs appear more often: absence of thickenings or presence of thin pleural thickenings, smooth aspect and parietal location of disease.
