To retrospectively analyze clinical presentations, pulmonary function parameters and radiological appearance in patients with combined pulmonary fibrosis and emphysema (CPFE) syndrome. ⋯ The co-existence of lower lung fibrosis and upper lung emphysema was found in some smokers. Patients with CPFE syndrome can present with a normal or nearly normal lung volume but a remarkable impairment in gas exchange. A high prevalence of pulmonary hypertension is seen in CPFE syndrome. Further studies to elucidate the pathogenesis and to explore the treatment and prognosis are warranted.
