Abstract:
Objective To study the imaging features and pathological characteristics of MCRCC in order to improve its diagnostic accuracy. Methods The multi-phase SCT and contrast-enhanced ultrasound were performed in 18 cases of MCRCC proved by the pathology before their operation.The imaging features of MCRCC in 18 patients were reviewed. Results All tumors appeared as well-defined round or oval multilocular cystic masses composed of serous fluid with regular thin cystic wall and an irregular renal shape. There were thin coarse septum(6 cases), thick septum(8 cases) and septum with nodule(4 cases) of all the tumor. Dynamic SCT presented enhancement from slight to moderate degree in thin septum cases, obviously homogeneous enhancement in septum with nodule cases and two different previously enhancement in thick septum cases, so did CEUS. The degree of enhancement correlated well positively with the dynamic SCT and CEUS in 18 cases of MCRCC(P ＜0.05). Conclusion The typical imaging features of MCRCC are multilocular cystic masses composed of serous fluid with regular thin cystic wall, thin coarse septum, thick septum and septum with nodule. There are enhancement from slight to moderate degree in septum cases by SCT and CEUS. The imaging features of SCT and CEUS are integrated in MCRCC, which may improve the accurate diagnosis of MCRCC and provide strong guidance for the clinical treatment.
