Bilateral double contour on the cardiac borders and a review of the literature

Abstract

There is not a systematic review about double contour in thoracic radiography in the literature. We present a 64-year-old male patient with bilateral double density sign in chest X-ray. The case was admitted with complaints of syncope to the emergency department. Arterial blood gas analysis was consistent with respiratory failure. A mucoid impac-tion in the right lower lobe was aspirated during bronchos-copy. Chest computerized tomography demonstrated a huge diaphragmatic hernia and intrathoracic stomach in the posterior mediastinum. The patient was treated with intra-venous diazepam for delirium tremens. All related papers were reviewed with Google and Pubmed search using keywords “double contour sign” or “double density sign”. In conclusion, pulmonary, cardiac, and retrocardiac medi-astinal diseases can cause double density sign.

Kalp sınırlarında iki taraflı çift kontur ve literatürün incelenmesi

Abstract

Literatürde toraks radyografisinde çift konturdan bahseden sistematik bir derleme yoktur. Akciğer grafisinde bilateral çift dansite olan 64 yaşındaki erkek olguyu sunuyoruz. Olgu acil servise bayılma yakınması ile başvurmuştu. Arter kan gazı analizi solunum yetmezliği ile uyumluydu. Sağ alt lobdaki mukus tıkacı bronkoskopi ile aspire edildi. Göğüs bilgisayarlı tomografisi dev bir diyafragma hernisini ve arka mediyastende intratorasik midenin varlığını gösterdi. Hasta deliryum tremens nedeniyle intravenöz diazepam ile tedavi edildi. Google ve Pubmed “çift kontur bulgusu” veya “çift dansite bulgusu” anahtar kelimeleri ile taranıp tüm ilişkili yazılar incelendi. Sonuç olarak pulmoner, kardiyak veya arka mediyastinal hastalıklar çift dansite bulgusuna neden olabilir.
