A Radiologic Review of Visceral Artery Aneurysms
Visceral artery aneurysms are rare, with a historical prevalence of 0.1% to 2% during autopsy.1,2 However, more visceral artery aneurysms are being identified in practice. This is the result of biliary tract instrumentation, arterial catheterization for local regional treatment of hepatic malignancies, liver transplantation, and incidental findings from the widespread use of abdominal imaging.1 (Source: Contemporary Diagnostic Radiology)

Primary Lymphoma of Bone
Lymphoma of bone is not uncommon, accounting for 7% of primary bone malignancies and 5% of extranodal lymphomatous involvement.1 Osseous lymphoma is divided into four groups based on extent of disease: (1) a solitary osseous lesion, (2) multifocal osseous involvement without soft tissue or nodal involvement, (3) simultaneous osseous and nodal/soft tissue involvement, and (4) osseous involvement presenting more than 6 months after an established diagnosis of lymphoma.1 Primary bone lymphoma is defined by the World Health Organization as a malignant lymphoid neoplasm of bone, either at a single bone site with or without regi...

Gastrointestinal Stromal Tumors and Associated Tumors
Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor in the gastrointestinal tract. GISTs are found most commonly in the stomach; followed by the small bowel, colon and rectum, esophagus, and extragastrointestinal tract. On initial staging evaluation of GISTs, the radiologist must determine the organ of origin; size; local invasion; and distant metastases, typically to the liver and peritoneum. If additional lesions are found in other locations, then syndromes related to GISTs must be considered. These include Carney triad, Carney-Stratakis syndrome, neurofibromatosis type 1 (NF1), and familial GIST s...

The Psoas Major Muscle at the Lumbar Spine: Review of Its Anatomy, Anatomic Variants, Biomechanics, and Affecting Pathologies
The anatomy of the psoas major muscle (PMM) is known, although some details about its origin, size, and morphology remain partially understood. The anatomic variants of the PMM are unreported almost in their entirety. The implications of these variants on the biomechanics of the muscle have not been investigated thoroughly. There are no dedicated reports on the prevalence of these anatomic variants, nor about their distribution in relation with ethnicity and sex. The PMM is a hip flexor and a stabilizer of the lumbar spine. Whether the normal functions of the PMM are altered in individuals with anatomic variants of the PMM...

The Pathologic Diaphragm
A brief review of diaphragmatic anatomy and functionality is necessary before the discussion of the various pathologic diaphragmatic entities. The diaphragm begins developing during the first trimester and is composed of four primary structures, including the transverse septum (which ultimately becomes the central tendon); pleuroperitoneal folds, esophageal mesentery; and the muscular body wall.1 Three separate normal diaphragmatic openings or “hiatuses” are present, which allow for communication between the thoracic and abdominal cavities (Figure 1). The inferior vena cava (IVC) hiatus is located in the midportion of ...

Acute Abdominal Pain in the Elderly
This article reviews common intra-abdominal senescent changes in the elderly and discusses appropriate protocol modifications that address comorbidities and optimize diagnostic quality. Various common and uncommon causes of acute abdominal pain in the elderly will be evaluated in the following categories: visceral, solid organ, and vascular pathology.

Fibroepithelial Lesions of the Breast: Key Imaging and Pathologic Features
Fibroepithelial lesions are encountered commonly in a breast imaging practice and may be detected clinically or by imaging. They represent a spectrum of solid breast masses ranging from benign fibroadenomas to malignant phyllodes tumors and are differentiated pathologically by varying degrees of stromal and glandular elements. Clinical history and breast examination, mammography, breast ultrasound, and MRI may further help with characterization of the breast masses, but none of these procedures can unequivocally differentiate benign from malignant lesions. Depending on imaging features, work-up of the breast mass may inclu...
