Case contributed by:
Dr Andrew Dixon
Presentation:
Recurrent nose bleeds.
Patient Data:
Age: 12 years
Gender: Male
Multiple pulmonary nodules are seen on the chest radiograph, the largest in the right mid-zone. There is a prominent vessel leading to this nodule.
Intravenous contrast enhanced CT demonstrates multiple pulmonary arteriovenous malformations ranging in size from small to moderately large.
Case Discussion:
The multiplicity of AVMs and history of epistaxis suggests hereditary haemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu syndrome.
