Aim. Our paper aims to discuss the radiological and clinical findings of chronic pulmonary embolism (CPTE) and chronic thromboembolic pulmonary hypertension (CTEPH) over the patient's findings. Material and Methods. We present the case of a 49-year-old female patient with CPTE and CTEPH. Results and Discussion. CPTE is a long-term consequence of unresolved pulmonary embolism. Since pulmonary embolism's frequency dramatically increased during the COVID-19 pandemic, CPTE once again has become one of the current topics of scientific conversations. Radiology is a gold standard for diagnosis. CPTE is a complex pathology and multisystemic evaluation is essential. Conclusions. Computed tomography (CT) findings can be classified into four groups: vascular, parenchymal, and systemic findings due to pulmonary hypertension and collateral formations. Changes in the ratio of right and left ventricle, size of the pulmonary artery, bowing sign and presence of mosaic attenuation should be directed us to the diagnosis of CTEPH in the patient with CPTE.
