Contrast-Enhanced Digital Mammography Screening for Intermediate-Risk Women With a History of Lobular Neoplasia

A 30-year-old man presented with colicky abdominal pain for 2 months, associated with occasional episodes of bilious vomiting. He had a history of similar complaints at the age of 16 and 26 years. Contrast-enhanced computed tomography abdomen was consistent with a diagnosis of left paraduodenal hernia. On laparoscopy a 3 × 3 cm hernial defect was identified in the left paraduodenal fossa (fossa of Landzert). Contents were jejunal, and proximal ileal loops which were dilated and edematous. Anterior border of the sac was formed by the inferior mesenteric vein and left branch of the left colic artery. Initial reduction of contents was easy. However, complete reduction proved to be difficult due to adhesions with the sac opening, the hernial sac instead laid open by dividing the Inferior Mesentric Vein (IMV) (anterior border of defect) using a vascular stapler. The patient was discharged on postoperative day 3 in a stable condition. On follow-up the patient is doing well.

2D Images

Abstract Objective Low-energy (LE) images of contrast-enhanced mammography (CEM) have been shown to be noninferior to digital mammography. However, our experience is that LE images are superior to 2D mammography. Our purpose was to compare cancer appearance on LE to 2D images. Methods In this IRB-approved retrospective study, seven breast radiologists evaluated 40 biopsy-proven cancer cases on craniocaudal (CC) and mediolateral oblique (MLO) LE images and recent 2D images for cancer visibility, confidence in margins, and conspicuity of findings using a Likert scale. Objective measurements were performed using contrast-to-noise ratio (CNR) estimated from regions of interest placed on tumor and background parenchyma. Reader agreement was evaluated using Fleiss kappa. Per-reader comparisons were performed using Wilcoxon test and overall comparisons used three-way analysis of variance. Results Low-energy images showed improved performance for visibility (CC LE 4.0 vs 2D 3.5, P < 0.001 and MLO LE 3.7 vs 2D 3.5, P = 0.01), confidence in margins (CC LE 3.2 vs 2D 2.8, P < 0.001 and MLO LE 3.1 vs 2D 2.9, P < 0.008), and conspicuity compared to tissue density compared to 2D mammography (CC LE 3.6 vs 2D 3.2, P < 0.001 and MLO LE 3.5 vs 2D 3.2, P < 0.001). The average CNR was significantly higher for LE than for digital mammography (CC 2.1 vs 3.2, P < 0.001 and MLO 2.1 vs 3.4, P < 0.001). Conclusion Our results suggest that cancers may be better visualized on the LE CEM images compared with the 2D digital mammogram.

A 36-year-old non-smoker, chronic alcoholic female presented with recurrent episodes of epigastric pain and vomiting in the last 10 days. H/o similar episodes of pain 3 times, with last episode was noted 2 months back. She also had history of vomiting (3 episodes). Jaundice/melena/steatorrheas was not observed. Subsequently, contrast-enhanced computed tomography (CECT) of the patient was done and it showed well defined multiple cystic lesions with peripheral wall enhancement involving head and body of pancreas, largest measuring 24 X 22 X 22 mm in the head of the pancreas, the lesion was seen abutting antro-pyloric region anteriorly. Main pancreatic is mildly dilated measuring 4 mm in diameter. A well-defined heterogeneously hypodense (necrotic) para duodenal lesion, was noted inferior to uncinate process, m/s 22 X 20 X 20 mm, which is indicative of lymph nodal deposit. On magnetic resonance cholangiopancreatography (MRCP): few cystic lesions were seen scattered in the pancreatic parenchyma, with one of the cysts showing communication with main pancreatic duct (MPD) ab.

Purpose: to study the possibilities of contrast enhanced dual-energy spectral mammography (CESM) in the diagnostics of malignant tumors in the breast.Material and methods. Forty-seven patients with suspicious for breast cancer (BC) lesions underwent CESM. Digital mammography (MMG) and post-contrast images were correlated with the results of path morphological studies after surgery or puncture biopsy was performed.Results. Sensitivity, specificity and overall accuracy in the diagnostics of breast cancer were 83.3%, 85.7%, 85.1% for digital mammography and 91.6%, 91.4%, 91.4% for CESM, respectively. The positive predictive value was 66.6% for digital MMG and 78.5% for CESM. The negative predictive value (NPV) was 96.9% for the CESM and exceeded NPV of the digital MMG, which was 93.7%.Conclusion. Thus, these findings suggest that CESM is an effective method for the diagnostics of malignant tumors in the breast.
