Radiation diagnosis of single lung hemangioendothelioma in combination with atypical carcinoid – literature review and clinical observation

Abstract

A clinical case of epithelioid hemangioendothelioma (EHEL) in combination with atypical lung carcinoid (AC) is presented. According to computed tomography (CT), magnetic resonance imaging (MRI) in the lower lobe of the right, a solid-fluid formation was easily identified, associated with the lower lobe artery, slightly accumulating 18F-FDG. CT and PET monitoring for 6 years did not reveal any negative dynamics of the lesion. After suffering from Covid-19 associated pneumonia, the patient developed episodes of hemoptysis and shortness of breath. CT and PET scans revealed an increase in the size of a focal formation in C6 of the right lung, a significant increase in metabolic activity, and accumulation of radionuclide in the mediastinal lymph nodes and the spinous process of the ThII vertebral body. Lower bilobectomy revealed EHEL and a previously unrecognized atypical carcinoid with metastases to the bifurcation lymph nodes.
