The Correlation between Morpho-Dynamic Contrast-Enhanced Mammography (CEM) Features and Prognostic Factors in Breast Cancer: A Single-Center Retrospective Analysis.

Breast cancer, a major contributor to female mortality globally, presents challenges in detection, prompting exploration beyond digital mammography. Contrast-Enhanced Mammography (CEM), integrating morphological and functional information, emerges as a promising alternative, offering advantages in cost-effectiveness and reduced anxiety compared to MRI. This study investigates CEM's correlation with breast cancer prognostic factors, encompassing histology, grade, and molecular markers. In a retrospective analysis involving 114 women, CEM revealed diverse lesion characteristics. Statistical analyses identified correlations between specific CEM features, such as spiculated margins and irregular shape, and prognostic factors like tumor grade and molecular markers. Notably, spiculated margins predicted lower grade and HER2 status, while irregular shape correlated with PgR and Ki-67 status. The study emphasizes CEM's potential in predicting breast cancer prognosis, shedding light on tumor behavior. Despite the limitations, including sample size and single-observer analysis, the findings advocate for CEM's role in stratifying breast cancers based on biological characteristics. CEM features, particularly spiculated margins, irregular shape, and enhancement dynamics, may serve as valuable indicators for personalized treatment decisions. Further research is crucial to validate these correlations and enhance CEM's clinical utility in breast cancer assessment.

Isolated rupture of renal pelvis after blunt chest trauma: First description of a case.

Isolated post-traumatic rupture of renal pelvis (IPTRRP) is an extremely rare condition and only a few cases following blunt abdominal trauma have been reported in the literature. To our knowledge, no cases of IPTRRP following blunt chest trauma have been reported. We present the case of an 84-year-old woman who was admitted to our Emergency Department due to persistent left flank pain that started after she had fallen to the ground 4 days before, with blunt trauma on her chest. CT showed a rupture of the left renal pelvis with contrast extravasation, associated with multiple rib fractures. No renal and other parenchymal injuries were detected. The patient was managed conservatively with the implantation of a ureteral stent and discharged in good clinical conditions. Our case shows the first description that IPTRRP might be an uncommon but possible complication of blunt chest trauma and must be included in the differential diagnosis.
