If You See a Round Density on Chest X-ray in a Cyanotic Child, Suspect Pulmonary Arteriovenous Malformation
We reported a 15-month-old infant who presented with dyspnoea and cyanosis. She was hospitalised with the diagnosis of bronchopneumonia but the patient showed no clinical improvement with antibiotic treatment. There was persistent cyanosis and there was progressive radiological change on anterior-posterior chest X-ray (CXR) during follow-up. A round density was noted on the CXR, tests were performed to exclude pulmonary arteriovenous malformations (PAVM) and the diagnosis was made. Transcatheter embolisation of the pulmonary arteriovenous malformation was performed with an Amplatzer Vascular Plug. In patients with suspected pneumonia resistant to treatment, presence of round or oval density on CXR should raise the suspicion of PAVM.
