目的分析肺棘球蚴病的CT表现,评价CT检查的价值。方法23例经手术病理证实为肺棘球蚴病的患者均经CT检查,分析CT表现特点,并对照手术病理结果。结果23例均为单发病灶,右肺15例,左肺8例,下肺多于上肺;CT检查大致分为2型:单纯肿块型7例,表现大小不等、外形欠规则的实性肿块,边缘毛糙,可见浅分叶,周围肺野可见少许纤维影,6例病灶内见弧形或斑点状钙化;肿块呈囊腔型16例,表现为肺内含囊腔肿块,囊腔大小不等,可呈偏心改变;病灶呈球形或不规则型,边缘毛糙,欠光整,周围肺野见棘状或片絮状改变,4例因囊膜剥离形成“水蛇征”或“飘带征”;囊肿钙化7例,表现为囊壁呈弧线形钙化,或伴有内容物的斑点状钙化。结论CT检查能准确显示肺棘球蚴病的部位和形态特征,对该病的诊断和治疗有重要意义。
Objective To analyze the CT findings of pulmonary alveolar echinococcosis and evaluate the value of CT examination. Methods Twenty - three patients with pathologically confirmed pulmonary alveolar echinococcosis were examined by CT. The CT features were analyzed and the pathological findings were compared. Results All the 23 cases were single lesion. There were 15 cases of right lung, 8 cases of left lung and more of the lower lung than the upper lung. The CT examination was roughly divided into 2 types: simple mass type in 7 cases with different size and irregular shape There were 16 cases with cystic cavity in 16 cases, which showed cystic mass in the lung and cyst in the lung cavity Ranging in size, can be eccentric change; lesions were spherical or irregular, rough edges, under the whole light, see the spine around the lung field or flake floc changes, 4 cases of peeled off due to the formation of “water snake sign” or “streamers Sign ”Cyst calcification in 7 cases, showed an arcuate wall calcification, or with the contents of the plaque calcification. Conclusion CT examination can accurately show the location and morphological features of pulmonary alveolar echinococcosis and is of great significance for the diagnosis and treatment of the disease.
