Thick section reformatted images of CT are superior in demonstration of intrapulmonary shunts and dilated vascular structures compared with thin section axial source images; so we recommend that thorax CT of cirrhotic patients must be evaluated with thick section reformatted images for the determination of intrapulmonary shunts and dilated vascular structures.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Respiratory complications, which range from mild hypoxemia to hepatopulmonary syndrome, can occur due to some mediators within the circulation in end-stage liver disease.
📊
Key Findings & Data:We reported a 37-year-old woman with previously known liver cirrhosis, presented with new onset exertional dyspnea.
💡
Conclusion & Impact:Thick section reformatted images of CT are superior in demonstration of intrapulmonary shunts and dilated vascular structures compared with thin section axial source images; so we recommend that thorax CT of cirrhotic patients must be evaluated with thick section reformatted images for the determination of intrapulmonary shunts and dilated vascular structures.

Abstract

Respiratory complications, which range from mild hypoxemia to hepatopulmonary syndrome, can occur due to some mediators within the circulation in end-stage liver disease. Intrapulmonary vascular dilatations and shunts are the reasons of these complications. Thoracic imaging modalities such as radiography and computed tomography (CT) can be performed to evaluate these vascular pathologies. We reported a 37-year-old woman with previously known liver cirrhosis, presented with new onset exertional dyspnea. There were intrapulmonary shunts and dilated vascular structures on her thorax CT. She was diagnosed with hepatopulmonary syndrome by clinical symptoms, laboratory and imaging findings. Thick section reformatted images of CT are superior in demonstration of intrapulmonary shunts and dilated vascular structures compared with thin section axial source images; so we recommend that thorax CT of cirrhotic patients must be evaluated with thick section reformatted images for the determination of intrapulmonary shunts and dilated vascular structures.

Özet

Son dönem karaciğer hastalığında dolaşımdaki bazı mediatörlere bağlı olarak hafif hipoksemiden hepatopulmoner sendroma kadar uzanan spektrumda solunum komplikasyonları görülebilmektedir. İntrapulmoner vasküler dilatasyonlar ve şantlar bu komplikasyonlardan sorumludur. Radyografi ve bilgisayarlı tomografi (BT) gibi toraks görüntüleme modaliteleri bu vasküler patolojilerin değerlendirilmesinde kullanılabilir. Bu olgu sunumunda bilinen karaciğer sirozu olan ve yeni başlayan egzersiz dispnesi ile başvuran 37 yaşında kadın hastanın direkt grafi ve BT bulgularından bahsettik. Hastanın toraks BT’sinde intrapulmoner şantlar ve dilate vasküler yapılar mevcuttu. Hastamız, klinik, laboratuvar ve radyolojik bulguları sonucunda hepatopulmoner sendrom tanısını aldı. Kalın kesit reformatlı BT görüntüleri intrapulmoner şantlar ve dilate vasküler yapıları kaynak görüntü olarak kullanılan ince kesit BT’den daha iyi bir şekilde göstermiştir. Bu nedenle siroz hastalarında, intrapulmoner şantlar ve vasküler dilatasyonların belirlenmesinde toraks BT’lerinin reformatlı kalın kesitlerle de değerlendirilmesini önermekteyiz.
