Prakriti Shukla, Hanni Vasudev Gulwani
Dermatofibrosarcoma protuberans is a rare soft tissue sarcoma that arises from the dermis and invades deeper tissues. Usually, it behaves as an intermediate grade malignancy but in rare instances, it can metastasize. Frequent occurrences have been observed in trunk and extremities but involvement of the breast has rarely been reported. Therefore, dermatofibrosarcoma protuberans (DFSP) breast often masquerades primary breast malignancy on clinical and radiological grounds. Histomorphology and immunohistochemistry are helpful in making a definitive diagnosis...

PURPOSE: Low contrast (LC) detectability is a common test criterion for diagnostic radiologic quality control (QC) programs. Automation of this test is desirable in order to reduce human variability and to speed up analysis. However, automation is challenging due to the complexity of the human visual perception system and the ability to create algorithms that mimic this response. This paper describes the development and testing of an automated LC detection algorithm for use in the analysis of magnetic resonance (MR) images of the American College of Radiology (ACR) QC phantom...

In resource-limited countries, the diagnosis of pulmonary tuberculosis (TB) is based on clinical findings, chest radiography and the demonstration of acid-fast bacilli in sputum. Few data are available on the use of ultrasound (US) to diagnose pulmonary TB. Chest US was performed in patients with lung TB from a rural African setting, to look for signs of the disease and to clarify the role US may have in the diagnosis of pulmonary TB. Sixty adult patients diagnosed with lung TB underwent chest US. All patients had abnormal findings...

Several lines of evidence suggest a definite and unique link between CNS demyelinating diseases and autoimmune thyroid disease (AITD). The aim of the current study was to systematically compare the clinical and laboratory features of patients with coexistent AITD and CNS demyelinating disease with those of patients with just CNS demyelinating disease. Forty-four patients with coexisting CNS demyelinating disease and AITD were identified and their clinical and radiological features were recorded. Blood and DNA were collected and tested for HLA type and for the response of T cells and antibodies to a variety of antigens...

Diffuse idiopathic skeletal hyperostosis is a bone disease characterized by ossification of spinal ligaments and peripheral entheses. Currently, we still use the classic classification criteria that do not include extraspinal manifestations. A number of authors agree on the need to revise them. We present 3 patients in which a diagnosis of diffuse idiopathic skeletal hyperostosis could not be established if we apply those criteria, but they have fully compatible clinical and radiological manifestations of hyperostotic disease...

INTRODUCTION: The mainstay therapy for Parkinson's disease (PD) relies on L-3,4-dihydroxyphenylalanine (L-DOPA) plus a DOPA-decarboxylase inhibitor. However, their effects on colonic dysmotility and inflammation observed in PD are undetermined. This study examined the effects of L-DOPA plus benserazide (BE) on colonic motility and inflammation in rats with central nigrostriatal dopaminergic denervation. METHODS: Neurodegeneration was induced by 6-hydroxydopamine (6-OHDA) injection into the medial forebrain bundle (MFB)...

Cigarette smoking is the most frequently encountered risk factor for chronic obstructive pulmonary disease and lung cancer. The latest American Thoracic Society÷European Respiratory Society classification of idiopathic interstitial pneumonia includes two entities related to smoking habits: respiratory bronchiolitis-associated interstitial lung disease and desquamative interstitial pneumonia. The new approach to diagnosis is to combine pathological pattern with clinical and radiological data. Lung biopsy is no longer considered the "gold standard" for diagnosis, but as a part of the diagnosis, which shall be set only after the pulmonologist, radiologist and pathologist reviewed all clinical, imaging and pathological aspects...

Glioblastoma multiforme (GBM) is the most common and aggressive type of the primary brain tumors with pathologic hallmarks of necrosis and vascular proliferation. The diagnosis of GBM is currently mostly based on histological examination of brain tumor tissues, after radiological characterization and surgical biopsy. The ability to characterize tumors comprehensively at the molecular level raises the possibility that diagnosis can be made based on molecular profiling with or without histological examination, rather than solely on histological phenotype...

Lung infections are an important cause of morbidity and mortality, particularly because of the rising antimicrobial resistance. According to the clinical setting, they can be categorized as community-acquired pneumonia and hospital-acquired pneumonia. Radiological patterns of lung infections are lobar consolidation, bronchopneumonia, interstitial pattern, and nodular pattern. In addition, typical imaging features of several infections serve as "red flag signs" in reaching a diagnosis or altering the management...

Intrahepatic cholangiocarcinomas account for approximately 20% of cases of cholangiocarcinomas. Three growth patterns or morphologic subtypes exist, including mass-forming, periductal-infiltrating, and intraductal-growth subtypes. Knowledge of these morphologic subtypes and their radiologic appearance aids in timely diagnosis, a key to optimizing patient outcomes. The morphologic variability of intrahepatic cholangiocarcinomas has a direct impact on the diagnostic sensitivity and specificity of various diagnostic imaging modalities, including ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI)/magnetic resonance cholangiopancreatography (MRCP), and positron emission tomography (PET)...

REVIEW
Ilkay Cinar, He Wang, James R Stone
Non-infectious aortitis may be caused by several distinct systemic rheumatologic diseases. In some patients, aortitis is identified either pathologically or radiologically in the absence of clinical evidence of a systemic vasculitis. By consensus nomenclature, such cases are referred to as clinically isolated aortitis (CIA). Some systemic disorders may initially present as CIA including giant cell arteritis (GCA), IgG4-related disease, infectious aortitis, and granulomatosis with polyangiitis. CIA most commonly occurs in women of European descent over the age of 50 and, thus, mirrors the gender, age, and geographic distribution of GCA...
