A case of juxta-articular myxoma of the knee.

This 9-year-old girl presented with a painful mass in the posterolateral aspect of her right knee. Excisional biopsy of the mass revealed a juxta-articular myxoma. The differential diagnosis for such an intra- or periarticular mass should include meniscal cyst, parameniscal cyst, ganglion cyst, juxta-articular myxoma, focal nodular PVNS, and desmoid tumor.

Mammography of the male breast.

Mammography of the male breast accounts for less than 1% of mammographic examinations done in breast imaging centers [1]. The purpose of this pictorial essay is to familiarize readers with diseases of the male breast and their mammographic manifestations that were observed during a 40-month period at the VA Medical Center, West Los Angeles. The most common presenting signs and symptoms that lead to a request for a mammograph in these men included an enlarging breast, a palpable lump, and breast tenderness.

Women's attitudes about receiving mammographic results directly from radiologists.

Purpose: To learn what women think about the communication of mammographic results directly to them by radiologists.

Materials And Methods: Three hundred seven women completed a survey at the time of mammographic examination. The women were asked to indicate the strength of their agreement with seven statements about the communication of mammographic results directly to them by the radiologist.

Mammography quality assurance from A to Z.

Quality assurance (QA) refers to all planned, systematic activities that instill confidence that quality mammography is being performed. Quality control (QC) refers only to the technical aspects of the examination. Standardized labeling of mammograms and the format for mammographic reports are important parts of a QA program; recommendations for both have been published by the American College of Radiology.

Case report 828: Plexiform neurofibroma of the tibial nerve invading the medial and lateral gastrocnemius muscles and plantaris muscle.

A 5-year-old boy presented with a several-year history of swelling of his calf and muscular weakness. MRI demonstrated abnormal signal and diffuse enlargement of the gastrocnemius muscle. Pathological examination revealed plexiform neurofibroma, and the diagnosis of neurofibromatosis was subsequently made.

Magnetic resonance imaging of glenohumeral instability.

Glenohumeral instability refers to subluxation or dislocation of the glenohumeral joint. This painful disorder is particularly common in the athletic population, and the individual with instability may present with a variety of clinical complaints. This paper addresses current theories regarding the pathophysiology of glenohumeral instability and illustrates magnetic resonance findings that can assist in diagnosis and treatment planning.

Diagnostic imaging of osteosarcoma.

The diagnosis, treatment planning, and follow-up evaluation of osteosarcoma rely heavily on a variety of imaging techniques. Plain roentgenography, radionuclide bone scanning, computed tomography, and magnetic resonance imaging play important roles in defining local tumor extent, detecting metastatic disease, and monitoring for recurrent tumor. Invasive studies such as angiography are now rarely necessary.
