Littoral cell angioma (LCA) is an extremely rare primary splenic tumor. There are few MRI and scintigraphic characteristics described. These characteristics may be most helpful in differentiating LCA from other primary vascular tumors. We present a…

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…

Background: Spondylolysis defects detected by nuclear scintigraphy but not by plain radiographs represent early lesions. Functional outcome and eventual bony union of these defects are unknown. Hypothesis: Defects with greater degree of healing…

Renal cell carcinoma is known as one of the "great mimics encountered in clinical medicine," along with syphilis and tuberculosis (1), It can present clinically as a wide range of symptoms, with a classic triad described as hematuria, pain, and a…

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…

Hypomagnesemia may be caused by renal losses (often related to drugs or diabetes), inadequate intake or inadequate intestinal absorption. Manifestations may include arrhythmias, particularly during myocardial ischemia or with digitalis use, and such…

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…

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…

Malignant peripheral nerve sheath tumors (MPNSTs) are rare soft tissue sarcomas that arise from peripheral nerve fibers and are derived from Schwann cells, perineural cells, or fibroblasts. MPNST is an aggressive neoplasm in which local recurrence is…

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,…

A case of a melanotic schwannoma presenting as a soft tissue mass of the abductors of the hip is reported. The radiographic findings suggested myositis ossificans, but several subtle findings raised the concern for something else. A bilobed…

We present a multiseptated mesenchymal hamartoma of the liver in a 10-year-old male patient, a rare benign tumor of childhood. The characteristic ultrasound and CT appearances of this unusual tumor are reviewed. A single septal calcification…

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…

Endocarditis due to Escherichia coli is rare. The case of a 79-year-old woman with E. coli bacteremia and multiple hemorrhagic cerebral infarcts is reported. A two-dimensional echocardiogram showed no evidence of a vegetation. While she was receiving…

Morphea is an inflammatory, sclerosing skin disorder that can involve the underlying soft tissues. Although the cause of morphea remains poorly investigated, genetic predisposition, immune dysregulation, and environmental factors have been…

Nasal chondromesenchymal hamartoma (NCMH) is an extremely rare benign pediatric tumor that was described in 1998. Only 19 cases are reported in the literature. We present a 15-year-old girl with nasal obstruction and recurrent sinusitis. Her medical…

Neurocysticercosis is a significant public health issue within the United States. Although cysticercosis was once thought to have been eradicated in the United States, the number of documented cases is rising and immigrants from endemic areas are at…

OBJECTIVE: To discuss the diagnosis and management of metastatic renal cell carcinoma presenting as a parotid mass by studying such cases. STUDY DESIGN: Retrospective review. METHODS: Identification of 24 previously reported cases of renal cell…

BACKGROUND: Ultrasonography is considered the most appropriate initial imaging study in the evaluation of acute appendicitis in children but has recently come under criticism with reports of low specificity and high indeterminate study rates,…

The Streptococcus pneumoniae (SP) urinary antigen (UAg) test is a commonly used assay. The purpose cif this study was to evaluate the test's actual performance in the clinical setting and determine the effects of renal function, grade of bacteremia,…

Background: Current American College of Cardiology/American Heart Association/Heart Rhythm Society (ACC/AHA/HRS) and European Society of Cardiology (ESC) guidelines recommend different strategies to avoid low-yield admissions in patients with…

Primary angiosarcoma of the breast is a rare entity. In this case report, we present a case of primary angiosarcoma of the breast in a young woman who presents with her entire right breast enlarged without skin coloration change or signs of mastitis.…

Background: Primary fallopian tube carcinoma (FTC) is an aggressive but rare tumor. Worldwide, more than 1,500 cases have been published, and about 20 new cases are added every year. isolated fallopian tube torsion (IFTT) is an unusual and uncommon…

This paper attempts to investigate the feasibility of using Raman spectroscopy for the diagnosis of colon cancer. Serum taken from 75 healthy volunteers, 65 colon cancer patients and 60 post-operation colon cancer patients was measured in this…

Reactive arthritis is an important source of morbidity. It is acquired through infectious agent diarrhea (food poisoning) or from sexual contact. Recognition is important because it allows a therapeutic approach that usually results in improvement of…

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…

Most children with psychosocial problems do not present for treatment in mental health settings. They are managed by primary care physicians. Children with psychosocial problems often have parents and/or families with psychosocial distress. The…
