The image performance of mucinous breast carcinoma on automated breast volume scanner and its pathologic features / 中华超声影像学杂志

ABSTRACT

Objective To explore the image performance of mucinous breast carcinoma( MBC) on automated breast volume scanner ( ABVS ) and its pathologic features ,for the purpose of improving the recognition of this disease on ABVS ,as well as diagnostic ability . Methods Retrospectively analyzed the sonogram and pathological data of 17 patients with 18 MBC lesions that included 9 PMBC ( pure mucinous breast carcinoma) and 9 MMBC( mixed mucinous breast carcinoma) ,all patients were examined by ABVS before operation and confirmed by pathology . Results Luminal A was the main molecular subtype of MBC ,as well as rarely lymph node metastases;The image of the MBC on ABVS mainly showed a round like or irregular mass ,isoechoic or slightly lower with posterior acoustic enhancement ,and clearly edge with microlobulated or angular ;While on the coronal plane ,it might presented unsmoothed contour ,retraction phenomenon and expansive growth pattern like a spherical nodular;The image characteristics of the PMBC and MMBC lesions on ABVS had no statistical difference( P > 0 .05) ,but the PMBC often performed isoechoic mass with clearly marge ,in contrast , the MMBC usually performed hypoechoic mass with indistinct and angular edge ,and the malignant image features on the coronal plane . Conclusions The three vertical sections of ABVS are beneficial to observe the morphological features of MBC completely ,which can help to identify it from the benign lesions ,reduce misdiagnosis ,and provide some guidance for MBC surgical treatment in the early stage .
