Audit of Prior Screening Mammograms of Screen-Detected Cancers: Implications for the Delay in Breast Cancer Detection.

When cancer is detected in a screening mammogram, on occasion retrospective review of prior screening (pre-index) mammograms indicates a likely presence of cancer. These missed cancers during pre-index screens constitute a delay in detection and diagnosis. This study was undertaken to quantify the missed cancer rate by auditing pre-index screens to improve the quality of mammography screening practice.

Shedding Light on T2 Bright Masses on Breast MRI: Benign and Malignant Causes.

While T2 hyperintense masses on breast MRI are often benign, there are several malignant etiologies that can also be T2 hyperintense. Delineation between benign and malignant entities is important for the accurate interpretation of breast MRI. Common benign T2 hyperintense masses include cysts, fibroadenomas, and lymph nodes.

Mass Forming Eosinophilic Cystitis in Pediatric Patients.

Eosinophilic cystitis (EC) is an uncommon inflammatory disorder of uncertain etiology that has been described in adult and pediatric populations. We describe 3 recent cases of EC that presented as a mass lesion in pediatric patients from the New England region of the United States. All patients were initially suspected to have a malignancy, and biopsy was performed, which ultimately led to the diagnosis of EC.
