Identificación de patrones tomográficos en el derrame pleural y su relación con el análisis citoquímico/citomorfológico de pacientes del Hospital General Monte Sinaí en el periodo 2022 - 2023.

Abstract

The main objective of the study was to determine the tomographic patterns in pleural effusion and their relationship with the results of the cytochemical/cytomorphological analysis in patients at the Monte Sinaí General Hospital during the period 2022-2023. Regarding the methodology, a retrospective analysis of a quantitative and observational nature was carried out, using a cross-sectional design. Data were collected on the observed tomographic patterns, such as the amount and distribution of fluid, the presence of pleural septation or thickening, and the involvement of adjacent structures. These data were compared with the results of cytochemical and cytomorphological analysis of the pleural fluid, which included measurements of proteins, LDH, glucose, albumin and other markers, as well as the identification of cells and their morphology. The results of the study revealed various correlations between tomographic findings and parameters of cytochemical and cytomorphological analysis. Four main tomographic patterns of pleural effusion were identified: loculated, free, encapsulated, and interlobar. The loculated and free patterns were significantly associated with pleural exudate, while the encapsulated and interlobar patterns were significantly associated with pleural transudate. The sensitivity and specificity of tomographic patterns for diagnosing the type of pleural effusion were moderate. Generalizing the conclusion, the study provided valuable information on the relationship between tomographic findings and the results of cytochemical and cytomorphological analysis in patients with pleural effusion. These findings may help improve the understanding and management of this medical condition, as well as guide more accurate and effective clinical and therapeutic decisions.
