Radiographic, CT, and High-Resolution CT Findings of Pulmonary Lymphangiectasis: A Case Report

肺部淋巴血管擴張症是一罕見異常，其特性為淋巴血管擴張。這類疾病大部分發生於新生兒或嬰兒，有極少發生於青少年或成人。本文報告一十六歲的女性病人，主訴為運動性呼吸困難及乾咳。胸部X光素片顯示雙側肋膜積水及肺門旁間質浸潤。電腦斷層攝影影像顯示雙側肋膜積水，心包膜積水及雙側下肺葉堅實變化。高解析度電腦斷層影像顯示肺間質變化及多處斑樣毛玻璃狀陰影。雖然淋巴血管擴張症在高解析度電腦斷層攝影並沒有示病徵象，但組織間隙的病變可在高解析度電腦斷層攝影顯現，這可提供有用的資料，再合併臨床所見，便可做出正確診斷。

Pulmonary lymphangiectasia (PL) is a rare malformation characterized by dilatation of pulmonary lymphatics. This condition occurs mainly in neonatal and newborn patients. A few cases of PL occur in the young children and adult have been reported. We report another case of a 16-year-old female patient presenting with exertional dyspnea and nonproductive cough. Chest radiography shows bilateral chylous pleural effusions and perihilar interstitial infiltration. Contrast enhanced computed tomography (CT) shows bilateral pleural effusions, pericardial effusion, and lower lobes consolidation. High-resolution CT reveals interstitial changes and patchy areas of ground-glass opacity. Although no pathognomonic findings on HRCT, the interstitial process depicted this imaging tool provides the information to suggest clinical diagnosis when combined with appropriate clinical findings.
