Pseudoaneurysm in the Axillary Tail of the Breast After A Core Needle Biopsy.

We present the case of a forty-year-old asymptomatic female with no personal or family history of breast cancer, who underwent a core needle biopsy (CNB) following the identification of a focal asymmetry in the right breast on screening mammography. Eight months later, a prominent adjacent vascular structure with a round outpouching was detected on breast ultrasound, confirmed as a post-biopsy pseudoaneurysm. Breast pseudoaneurysms, although exceedingly rare, result from inadvertent vessel puncture during core needle biopsies, particularly when larger gauge needles are used.

Surgically important bowel and/or mesenteric injury in blunt trauma: accuracy of multidetector CT for evaluation.

Purpose: To determine the accuracy of multidetector computed tomography (CT) in the detection of surgically important blunt bowel and/or mesenteric injury, to identify and describe the most reliable CT features of bowel and/or mesenteric injury, and to evaluate the performance of readers with different levels of expertise.

Materials And Methods: Institutional review board approval was obtained for this retrospective case-control study of 96 subjects with laparotomy-confirmed findings: 54 consecutive patients with bowel and/or mesenteric injury (surgically important and unimportant) (32 male patients, 22 female patients; mean age, 40.4 years +/- 17.

The prevalence of incidental simple ovarian cysts >or= 3 cm detected by transvaginal sonography in early pregnancy.

Objective: To determine the prevalence of simple ovarian cysts of >or= 3 cm diameter detected by transvaginal sonography (TVS) in a population of asymptomatic women in early pregnancy.

Methods: We conducted a retrospective review of 10,830 consecutive women presenting prior to 14 weeks' gestational age (GA) for early dating TVS. The records of all women with simple cysts >or= 3 cm in diameter were included.

Visualization of the ovaries in early pregnancy by transvaginal sonography.

Objective: To determine the frequency of visualization of the ovaries by transvaginal sonography (TVS) in a group of women in early pregnancy and to determine the onset of a decrease in sonographic visualization of the ovaries during this time.

Methods: The study population included all patients with an intrauterine pregnancy confirmed by the presence of a yolk sac,embryo, or fetus. The biometric data included crown-rump length and/or gestational sac mean diameter corresponding to < - 14 weeks' gestational age (GA).

Evaluation of bowel and mesenteric blunt trauma with multidetector CT.

Bowel and mesenteric injuries are detected in 5% of blunt abdominal trauma patients at laparotomy. Computed tomography (CT) has been shown to be accurate for the diagnosis of bowel and mesenteric injuries and is the diagnostic test of choice in the evaluation of blunt abdominal trauma in hemodynamically stable patients. Specific CT findings of bowel and mesenteric injuries include bowel wall defect, intraperitoneal and mesenteric air, intraperitoneal extraluminal contrast material, extravasation of contrast material from mesenteric vessels, and evidence of bowel infarct.
