Normal Axillary Lymph Node Variability Between White and Black Women on Breast MRI.

Rationale And Objectives: This study aimed to determine if there were differences in the imaging features of normal lymph nodes between white and black women using magnetic resonance imaging.

Materials And Methods: Following institutional review board approval, we identified white and black women who underwent breast magnetic resonance imaging from November 1, 2008 to December 31, 2013 at our institution. To identify normal lymph nodes for measurement, patients with any benign or malignant causes for lymph node enlargement and patients with any subsequent breast cancer in the following 2 years were excluded.

Acute Appendicitis: Use of Clinical and CT Findings for Modeling Hospital Resource Utilization.

Objective: The purpose of this study was to retrospectively investigate associations between baseline CT findings in suspected acute appendicitis and subsequent hospital resource utilization.

Materials And Methods: One hundred thirty-eight patients (76 male and 62 female patients; mean [± SD] age, 40 ± 21 years) who were admitted for suspected acute appendicitis and underwent baseline CT were included. A single radiologist reviewed CT examinations for appendiceal-related findings.

RADIOLOGY OF THE MONTH: Pulmonary Langerhans Cell Histiocytosis (PLCH).

Purpose: Obtaining a tissue sample diagnostic of pulmonary Langerhans cell histiocytosis (PLCH) by transbronchial biopsy is notoriously difficult. The condition's appearance on computed tomography is well described and singularly characteristic, perhaps adequate for definitive diagnosis. We propose an approach to diagnosis of these patients.

Anterior Cruciate Ligament Injury, Return to Play, and Reinjury in the Elite Collegiate Athlete: Analysis of an NCAA Division I Cohort.

Background: Graft survivorship, reinjury rates, and career length are poorly understood after anterior cruciate ligament (ACL) reconstruction in the elite collegiate athlete. The purpose of this study was to examine the outcomes of ACL reconstruction in a National Collegiate Athletic Association (NCAA) Division I athlete cohort.

Study Design: Case series; Level of evidence, 4.

Relationship between width of greater trochanters and width of iliac wings in tronchanteric bursitis.

Trochanteric bursitis is a common disorder that is characterized by inflammation of the bursa, superficial to the greater trochanter of the femur, leading to pain in the lateral hip, and often occurs because of acute trauma or repetitive friction involving the iliotibial band, the greater trochanter, and the bursa. In the study reported here, we hypothesized that the increased incidence of bursitis may be the result of the increased prominence of the trochanter in relation to the wings of the iliac crest. Distances between the outermost edges of trochanters and iliac wings were measured in 202 patients from the University of North Carolina Health Care System-101 without a known diagnosis and 101 with a clinical diagnosis of trochanteric bursitis.

Surprising evidence of pelvic growth (widening) after skeletal maturity.

Following an increase in length and width during childhood and adolescence, skeletal growth is generally assumed to stop. This study investigates the influence of aging on the dimensions of the pelvis and the L4 lumbar vertebra during adulthood. The dimensions of the pelvis, L4 vertebra, and femoral heads were calculated for 246 patients who had received pelvic and abdominal Computed Tomography scans from the UNC Health Care System.
