摘　　要：目的分析髓质海绵肾的CT表现及其临床意义。方法回顾性分析18例髓质海绵肾的CT表现。结果髓质海绵肾的CT表现为沿肾锥体排列呈放射状或簇状多发小斑点状结石或钙化影及周围有小囊状或梭形低密度影。双侧病变见于13例,单发右侧3例,左侧2例。结论CT有利于髓质海绵肾早期诊断并对发症的检出有重要的意义。Objective To analyze the CT findings of medullary＇ sponge kidney（MSK） and their clinical significance. Methods CT findings of 18 patients with MSK were analyzed retrospectively. Results On CT images, MSK lesions appeared as radiate, clustered, multiple small mottling calculi or calcified shadows those arranged along the renal pyramid. The periphery of the calcified foci was surrounded by small cystiform or shuttle-shaped shadows with hypodensity. The bilateral MSK lesions were found in 13 cases, while single right and left MSK lesions were found in 3 and 2 cases, respectively. Conclusion CT scanning plays an important role in the early diagnosis of MSK and its complications.
