Granulomatous angiitis leading to a pulmonary veno-occlusive disease-like picture

Pulmonary veno-occlusive disease (PVOD) is a rare cause of pulmonary hypertension characterised by extensive fibrotic occlusion of pulmonary veins. PVOD has a similar insidious presentation to idiopathic pulmonary arterial hypertension but responds poorly to conventional therapies and has a worse prognosis. The current study reports the case of a Caucasian female with a long history of progressive dyspnoea ultimately diagnosed as focal granulomatous venulitis leading to a pulmonary veno-occlusive disease-like pathology. The present study highlights the challenges in diagnosing and treating this condition.
