Multiple pulmonary arteriovenous malformations with the largest located in the left lower lobe. Previous wedge resection demonstrated at the superior segment of the left lower lobe.
Mildly enlarged spleen with several hypoattenuating areas which vary from rounded appearances reflecting vascular malformation and linear or wedge-shaped appearances favouring previous infarction. Both splenic arteries and veins are enlarged and there is an inferiorly projecting saccular aneurysm of the mid splenic artery.
Liver, pancreas, kidneys, gallbladder and adrenals are of normal appearance. No abdominal or pelvic lymphadenopathy. Absence of intraperitoneal fluid or gas. No abdominal or pelvic collection. No osseous lesion.
Conclusion: The presence of multiple pulmonary arteriovenous malformations and vascular abnormalities in the right upper abdomen are suggestive of an underlying diagnosis of hereditary haemorrhagic telangiectasia.
