肾钙乳的CT诊断

目的：探讨肾钙乳的CT表现及诊断价值。方法：对14例肾钙乳患者行常规CT检查并对图像进行分析。结果：14例CT图像均清晰显示钙乳囊肿全貌及“半月征”,其中4例转动体位后显示钙乳形成的半月形高密度影始终位于病灶最低处。病变均为单侧,平均直径2．4cm。其中囊肿型13例,积水型1例。结论：CT检查能清晰显示肾钙乳的特征性影像学改变,能准确地与其它疾病相鉴别,并能明确区分肾钙乳类型,为临床治疗提供可靠的病理、解剖资料。

CT diagnosis of renal milk of calcium

Objective To assess the CT manifestation an d its diagnostic value for renal milk of calcium (RMC). Methods Conventional CT examination was made for 14 patients of RMC and the imag es obtained were analyzed. Results CT clearly displayed the whole view of milky calcium cyst and its "half-moon sign". In 4 cases,th e half-moon high density formed by milk of calcium always located in the lowest part of the lesion with change of the body's position. All the lesions are unil ateral and their average diameter is 2.4 cm. Out of 14 patients, 13 are renal cy st type and 1 hydronephrosis type. Conclusions CT can di splay characteristic changes of RMC more clearly and distinguish it with other d iseases more reliably. CT can definitely discriminate types of RMC and provide more reliable pathologic and anatomic data.
