PURPOSE: To determine the sensitivity and specificity of a real-time elasticity imaging (EI) ultrasound (US) system in the characterization of breast lesions as benign or malignant. METHODS: A total of 208 patients with 251 lesions were scheduled to…

The incidence of metastases to the breast from nonbreast carcinoma is less than 1% of all breast cancers; of these, adenocarcinoma of the lung to breast is a small proportion (\textless0.1% of breast carcinomas). The imaging findings of a case of…

Diagnosis of a slow-growing mass of the cranium can be challenging. We present a rare clinical report of a 19-year-old woman with a unilateral mass of the frontal bone. Pathological diagnosis was hyperostosis, which is extremely rare in this age…

BACKGROUND: Diagnostic errors appear to be the most common, costly, and dangerous of all medical mistakes. There has been a notable increase on the focus of error prevention as part of a growing patient safety movement. However, diagnostic errors…

Cutaneous metastases from colorectal carcinomas occur infrequently, usually in the setting of disseminated disease. They most commonly appear on the abdominal wall or perineal area; metastases to other locations of the skin are rare. We describe a…

As the arboreal ape, Pongo, has an unusual ground ambulation adaptation, it was of interest to assess the impact of Pongo gait on patterns of arthritis. While osteoarthritis was not identified in Pongo, 11% of individual skeletons were afflicted with…

OBJECTIVE: To assess diagnostic implications of abnormalities of the pedal digital tufts and to identify features to facilitate distinguishing of spondyloarthropathy and leprosy. BACKGROUND: Better criteria for distinguishing between these disorders…

Trigeminal neuralgia is an uncommon disorder characterized by recurrent attacks of lancinating pain in the trigeminal nerve distribution. Typically, brief attacks are triggered by talking, chewing, teeth brushing, shaving, a light touch, or even a…

A 25-year-old black man presented with left-sided chest pain and cough for 3 days. His pain was pressure-like and nonradiating and was aggravated with movement and relieved when the patient lay at a 45 degrees angle. The patient denied fevers,…

We previously analyzed human prostate tissue containing stroma near to tumor and from cancer-negative tissues of volunteers. Over 100 candidate gene expression differences were identified and used to develop a classifier that could detect nearby…

BACKGROUND: Sarcoidosis is a systemic disease that may present as tattoo granulomas. OBJECTIVE: A patient with systemic sarcoidosis who developed a granulomatous reaction within a tattoo is presented to stimulate interest in this unusual phenomenon.…

Diffuse malignant mesothelioma is the most common primary tumor involving the pleura. Unfortunately, it also poses the most difficulty for physicians to diagnose and treat. Latency from the time of initial asbestos exposure, clinical features of…

OBJECTIVE: To determine whether magnetic resonance imaging (MRI) in pregnancy would help define a benign pelvic mass, thereby avoiding laparotomy. METHODS: During a 2-3-year period, five pregnant women with adnexal masses suspected to be leiomyomas…

Locked-in syndrome is a unique clinical condition associated with ventral pontine lesions. The locked-in state is characterized by tetraplegia and mutism with maintenance of alertness as well as vertical eye movements and eye blinking, by which…

The streptococcal toxic shocklike syndrome is a recently recognized, multisystem disorder that shares many of the features of staphylococcal toxic shock syndrome, but is caused by toxins elaborated by group A beta-hemolytic Streptococcus. We describe…

Anorexia nervosa and bulimia nervosa are eating disorders with distinct clinical presentations. Reduced caloric intake, a hallmark of both disorders, is manifested by self-induced starvation in anorexia and by binge eating and gastrointestinal…

Osteitis fibrosa cystica (brown tumors) can be a skeletal manifestation of advanced hyperparathyroidism, including parathyroid cancer. Severe osteitis fibrosa cystica can mimic metastatic bone diseases especially in patients with a history of cancer.…

Historically, appendicitis in the elderly is associated with higher morbidity and mortality. Ninety-six patients over 60 years of age with appendicitis treated over a 10-year period were reviewed. Only 20% presented classically with anorexia, fever,…
