Multiple pulmonary arteriovenous malformations

Case contributed by Dr Nehal Singla

Presentation

Dyspnoea for 3 months.

Patient Data

Age: 35 years
Gender: Female

Axial CT angiography images show multiple well defined nodular opacities scattered diffusely in bilateral lung parenchyma with the feeding vessel sign. They are supplied from pulmonary arteries and can be seen draining into the pulmonary veins and further left atrium, consistent with pulmonary arteriovenous malformations. No calcification is seen.

Case Discussion

This case demonstrates idiopathic multiple pulmonary arteriovenous malformations in a young female by the use of CT pulmonary angiography.

Pulmonary arteriovenous malformations have syndromic associations with Osler-Weber-Rendu syndrome in which multiple cutaneous arteriovenous malformations are also present.  In this case, no such syndromic association was found.
