Medical management does not reverse the effects of the disease, nor does it prevent its progression. Pulmonary thromboendarterectomy is the preferred treatment. We present the case of a patient in whom CTEPH was mistaken for an interstitial lung disease with mediastinal lymph node enlargement. The mediastinal lymph node enlargement was due to vascular transformation of the lymph node sinuses (VTS). This is an unusual case of chronic thromboembolic pulmonary hypertension with vascular transformation of the lymph node sinuses.
