Metastatic Merkel carcinoma complicated by transverse myelitis during immuno-oncological therapy; [Метастатическая карцинома Меркеля, осложненная на фоне иммуноонкологической терапии поперечным миелитом]

Objective. To present a unique clinical case of metastatic lesions of the perirenal space, ureter and bladder in Merkel's carcinoma with the development of transverse myelitis against the background of immuno-oncological therapy. Matherial and methods. The modern states of issue in diagnose and treatment of metastatic Merkel's carcinoma within multidisciplinary approach based on the medical documentation and radiological examinations (CT, MRI) was analysed in this article. Results. The unique clinical case of metastatic Merkel's carcinoma complicated by transverse myelitis during immuno-oncological therapy according to MSCT and MRI examinations report was demonstrated. Conclusion. Radiological examinations such as MSCT, MRI, ultrasound and PET/CT needed for detection, assess the incidence of tumor (metastasis and staging) and treatment efficiency control because of the rare occurrence and insufficient knowledge of Merkel's carcinoma. © 2022 Infectious Diseases: News, Opinions, Training.
