Bullous emphysema, a subtype of emphysema, is characterized by the irreversible enlargement of air-filled airways greater than 1cm in size. Often time, practitioners focus on smoking duration in pack years, and smoking frequency, rather than smoking onset, when assessing risk for development of bullous emphysema. Distinct radiographic findings on CT imaging can differentiate bullae from other lung pathologies, including lung cysts. Here, we present a young female with diffuse, bullous emphysema without an extensive smoking history. We aim to highlight the importance of smoking onset when determining risk for development bullous emphysema, as well as the role of CT imaging in the diagnosis of lung pathologies.
大疱性肺气肿是肺气肿的一种亚型，其特征是直径大于1厘米的含气气道不可逆扩大。通常，医生在评估大疱性肺气肿的发病风险时，关注的是吸烟包年数和吸烟频率，而非吸烟起始时间。CT成像上独特的影像学表现可将肺大疱与其他肺部病变（包括肺囊肿）区分开来。在此，我们报告一名年轻女性，患有弥漫性大疱性肺气肿，但无广泛吸烟史。我们旨在强调吸烟起始时间在确定大疱性肺气肿发病风险中的重要性，以及CT成像在肺部病变诊断中的作用。
