Utilidad de la tomografia multidetector en pacientes con lesiones hepáticas focales en comparación con la histopatología en SOLCA Cuenca 2010-2017.

Abstract

Background: The focal hepatic lesions represent a global confrontation, for the year 2012 in the United States, 700,000 cases of liver cancer were reported, of which 600,000 died. Nowadays, there is greater accessibility to imaging studies and an early and efficient diagnosis can be made in this problematic. Objective: To establish the utility of three-phase multislice computed tomography for the evaluation of hepatic lesions in comparison with the histopathological reports in the hospital of SOLCA Cuenca 2010-2017. Methodology: A diagnostic test validation study was carried out on all patients who attended the SOLCA Cuenca hospital in the period 2010 to 2017, evaluated by tomography and histopathology (Gold standard) in people with focal hepatic lesions, prior authorization by consent informed and the information was processed in software SPSS version 20.0 Results: 61.76% of patients represented the female sex with an average age of 63.5 years + - 16.26, the main characteristics of the liver lesions were; multiple; with homogeneous density, regular contours, solid consistency; and in the three-phase TCMD evaluation, in the simple phase they consisted of hypointense, in the arterial stage they were hyperdense or heterogeneous lesions, in the venous phase they presented peripheral enhancement and in the late stage they are hypodense in relation to the liver. 4.4% represented diagnosis of UFH (focal nodular hyperplasia) and lipoma, 27.9% hepatocarcinoma and metastasis 58.8%. In comparison with the histological one, a sensitivity and specificity of 100% was obtained with a correlation index between sperman diagnoses of 0.97%. Conclusions: the three-phase MDCT is very useful in characterizing a lesion as malignant or benign.
