The aim of the study was to reveal the features of the morphological structure and ultrasonic signs of Baker's cyst in patients of different ages. Material and methods. The study is based on a sonographic study of 213 patients (mean age 57.2±9.9 years) and 10 children aged 6 to 10 years with a detected Baker cyst. The size of the cyst was studied, its position, relationship with surrounding tissues was examined on sonographic equipment. In addition, parameters were measured, including the thickness of the synovium, the presence of septa and echo-inclusions, the degree of echogenicity of the contents of the cyst. All patients underwent open extirpation of the cyst followed by its morphological analysis. All manipulations were carried out after signing the informed consent of the patient or his legal representatives according to the recommendations "About legal, legislative and ethical norms and requirements in the performance of scientific morphological studies". Preparation of the histological material obtained after the removal of Baker's cyst was carried out according to standard procedures, followed by staining with hemothoxylin-eosin and Van Guzon. The obtained preparations were examined under a light microscope with the possibility of displaying an image on a computer monitor Results. In all adults with an identified Baker cyst, gonarthrosis of varying severity was detected, in contrast to children who had no such joint pathology. Morphological differences in the transformation of the tissues of education in different age groups were also significant. The difference was noted in the form of unexpressed dystrophy of the synovial membrane and the absence of necrotic and degenerative changes in the wall of the cyst in children. Conclusions. This work demonstrated several significant ultrasound and morphological differences in the popliteal cyst in children and adults. |
