Indeed, there is some evidence to suggest that PCH and pulmonary veno-occlusive disease are different forms of a similar disease process.[4] EpidemiologyThe prevalance of this disease is estimated to be < 1/million.[5] The usual age at presentation is between 20 and 40 but it has been reported in the newborn.[6] GeneticsAt least some cases appear to be due to mutations in the eukaryotic translation initiation factor 2-alpha kinase 4 (EIF2AK4) gene.[7] Clinical featuresThese are non specific. Typical symptoms include dyspnea, cough, chest pain and fatigue.[8] InvestigationsChest X ray may show enlargement of the heart and ill defined patchy lesions in the lung fields. CT chest typically shows wide spread ill defined centrilobular nodules of ground glass opacity. This is a nonspecific finding and may be seen in a number of pulmonary diseases. CT pulmonary angiography usually shows enlargement of the main pulmonary artery. When measured by echocardiography or pulmonary angiography, the pulmonary arterial pressure is typically elevated. DiagnosisLung biopsy is essential to make this diagnosis. This can be difficult if the pulmonary pressure is high. Differential diagnosis
AssociationsThis condition has been reported in patients with Ehlers Danlos syndrome,[9] CREST syndrome[10] and scimitar syndrome[11] TreatmentThe only definitive treatment for this condition currently is lung transplantation. Median survival without treatment is 3 years.[12] Imatinib may be of use.[13]Epoprostenol does not appear to be of use.[14]HistoryThis condition was first described in 1978.[15] NotesThis condition has been reported in cats.[16] and dogs.[17] References1. ^Ortiz-Bautista C, Hernández-González I, EscribanoSubías P.
