Abstract:
We herein report the first case of dyspnea with hemidiaphragm elevation in a 68-year-old woman with active giant cell arteritis (GCA), including successful treatment. Contrast-enhanced computed tomography showed a reduced density of the left ophthalmic artery and the left superficial temporal artery with increased soft tissue compared to the other side, indicating that the GCA had flared up and suggesting that the hemidiaphragm elevation might be caused by vasculitis-associated ischemia of the right phrenic nerve. Hemidiaphragm paralysis due to vasculitis-associated ischemia in patients with GCA needs to be distinguished from local infection, tumors, and hepatomegaly, which are the major causes of hemidiaphragm elevation.

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
Primary Symptoms of COPD:
Hyperpnea and Hyperventilation
