Abstract

PurposeIn this study, echogenicity and histopathological projections of parathyroid neoplasia in grey mode ultrasonography were compared with whole side imaging (WSI). The utility of the data obtained for clinical assessment was evaluated. MethodsIn 57 patients operated for hyperparathyroidism, the parathyroid gland was sampled in the sagittal plane. The lesion slides were scanned. The WSI was rendered digital. The histopathological slide images scanned with USG images were matched. With the İmage J program, the areas of cell types and morphological changes were measured. ResultsIn parathyroid neoplasms, hypoechoic areas were found to be matched with 21% [55.3%] chief cell, 2 [5.0%] oncocytic cell and 8%[20.0%] cystic morphology. Of the 57 patients, 26 [45.61%] had a cystic area. It was seen that hyperechogenic areas match more connective tissue areas than chef cell [p < 0.05]. There was less clear cell in hyperechogenic areas than iso-hyperechogenic areas [p < 0.05]. The ratio of fat tissue echogenicity was lower in hypoechoic areas than hyperechoic [p < 0.05]. There was a positive correlation between PTH and the entire tissue area [r = 0.377, p = 0.004]. A positive directional moderate linear relationship was found between blood calcium level and parathyroid adenoma [rho = 0.530, p = 0.009] and percentage [rho = 0.416, p = 0.048]. When atypical adenomas and adenoma cases were compared, no significant difference was found between the cystic and chief cell areas [p > 0.05]. ConclusionThe hypoechogenicity seen in USG was observed to be compatible with chief cell, hyperechogenic areas in USG were compatible with connective tissue and fat tissue. As the cystic area increased, blood calcium levels were higher in adenomas. We think that the results of this study will be guiding to evaluate the reflections of the detailed morphometric studies.
