XXXX : radiological findings.

@entity1 @entity10516 @entity75 @entity5 @entity733
PURPOSE: To evaluate the radiological, ultrasonographic, and magnetic resonance imaging (MRI) findings of idiopathic @entity10516 . MATERIAL AND METHODS: Between April 2002 and June 2005, the mammography, ultrasound, color Doppler ultrasound, nonenhanced MR, and dynamic MR findings of nine @entity1 with the preliminary clinical diagnosis of @entity5 and the final diagnosis of @entity10516 were evaluated. RESULTS: On mammography, asymmetrical focal densities with no distinct margins, ill-defined masses with spiculated contours, and bilateral multiple ill-defined nodules were seen. On ultrasound, in four @entity1 a discrete, heterogenous hypoechoic mass, in two @entity1 multiple abscesses, in one @entity1 bilateral multiple central hypo peripheral @entity75 , in two @entity1 heterogeneous hypo- and hyperechoic areas together with parenchymal distortion, and in one @entity1 irregular hypoechoic masses with tubular extensions and @entity733 were seen. Five of the lesions were vascular on color Doppler ultrasound. On MR mammography, the most frequent finding was focal or diffuse asymmetrical signal intensity changes that were hypointense on T1W images and hyperintense on T2W images, without significant mass effect. Nodular lesions were also seen. On dynamic contrast-enhanced mammography, mass-like enhancement, ring-like enhancement, and nodular enhancement were seen. The time-intensity curves differed from @entity1 to @entity1 and from lesion to lesion. CONCLUSION: The imaging findings of idiopathic @entity10516 have a wide spectrum, and they are inconclusive for differentiating @entity5 .
