May-Thurner syndrome is a complex disease diagnosed. Most often it occurs in young men with unrealized fatherhood. From September 2015 to December 2016 164 men are examined with suspected varicocele. The diagnosis of May-Thurner syndrome is confirmed in 6 patients (2.7 %). The average age of patients with May-Thurner syndrome was 26.4 ± 4.4g (17-38 years old). If you suspect a May-Thurner syndrome, diagnostic algorithm appropriate to start with a search of the asymmetry of blood flow in the iliac veins according to Doppler ultrasound. The optimum therapeutic tactics in these patients will be left intravascular stenting iliac veins in identifying positive pressure gradient in it more than 10 mm Hg compared with the inferior vena cava.
The article presents a clinical case of seminal vesicle lymphoma in a 73-year-old man who was sent for examination at the N.N. Blokhin National Medical Research Center of Oncology with suspected prostate tumor.
Background. The parasternal lymphatic collector is an important pathway of the lymph drainage from the breast in breast cancer patients. Evaluation of parasternal lymph nodes is not available during physical examination. To date, no algorithm for diagnostic imaging of the parasternal lymphatic pathway has been developed. The presence of metastases in parasternal lymph nodes upstages the breast cancer patient to a minimum of clinical stage III disease.Case description. We present the case of breast cancer progression in a 40-year-old woman. The patient received treatment for triple-negative stage IIA breast cancer (Т2N0M0) in 2018. In August, 2019, 18-FDG PET /CT images revealed a solitary metastasis in the parasternal lymph node. Ultrasound images also showed the same lymph node assessed by PET -CT and the additional parasternal lymph node metastasis. A fine-needle aspiration biopsy of both lymph nodes confirmed the specific involvement of the parasternal lymph nodes.Conclusion. Ultrasound scans are used to assess the axillary, subclavian and supraclavicular lymphatic collectors, but there is little evidence in the literature on the use of ultrasound in the assessment of parasternal lymph nodes. Our clinical case shows the feasibility of using ultrasound in assessing the status of the parasternal of lymph nodes, as well as the feasibility of performing fine-needle aspiration biopsy by ultrasound navigation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
