The authors report the case of a cystic pancreatic cancer with pulmonary metastasis to illustrate the unusual radiographic halo-sign appearance of nodular/consolidative change with surrounding ground glass pattern and also to highlight the histopathological background underlying this pattern.

We use galaxy-galaxy lensing to study the dark matter halos surrounding a sample of Locally Brightest Galaxies (LBGs) selected from the Sloan Digital Sky Survey. We measure mean halo mass as a function of the stellar mass and colour of the central galaxy. Mock catalogues constructed from semi-analytic galaxy formation simulations demonstrate that most LBGs are the central objects of their halos...

Cryptogenic organizing pneumonia (COP) is a rare pulmonary disorder of unknown etiology. COP with hemoptysis as the primary presenting symptom has rarely been reported. The present study reported a case of COP that resembled lung carcinoma with hemoptysis as the only clinical symptom. The patient recovered well following thoracoscope surgery. A literature review of 119 COP cases between 1995 an...

Imaging findings in the pulmonary aspergilloses can answer important clinical questions. Steroid-responsive chronic asthma due to allergic bronchopulmonary aspergillosis can be differentiated from simple asthma by computed tomography (CT) evidence of extensive and severe central bronchiectasis, mucoid impaction, or small airways lesions. The simple aspergilloma can be differentiated from the co...

Primary pulmonary diffuse large B-cell lymphoma (PPDLBCL) is extremely rare. Its clinical symptoms and signs are nonspe cific, and imaging features also have not yet been well-defined. Further description is important for the diagnosis and treatment of PPDLBCL. Herein, we reported a case of a patient who suffered from bilateral chest pain and dyspnea. Computed tomography (CT) of chest demonstra...

OBJECTIVE To determine the incidence of temporal arteritis (TA) in patients with polymyalgia rheumatica (PMR) using colour Doppler ultrasonography of the temporal arteries. METHODS Ultrasonography was performed in all 127 consecutive patients with newly diagnosed, active PMR seen between 1994 and 2000 and in 127 age- and sex-matched controls. RESULTS Of 102 patients with "pure" PMR, 8% had ...

We have carried out a detailed abundance analysis for 21 elements in a sample of four RGB stars in the outer halo globular cluster NGC 7492 (RGC 25 kpc); we find [Fe/H] = −1.82 dex inferred from Fe I lines (−1.79 from Fe II) using high dispersion (R=λ/∆λ=35,000) spectra obtained with HIRES at the Keck Observatory. Most elements show no sign of star-to-star variation within our limited sample. W...

Congenital smooth muscle hamartoma usually manifests at birth, but rarely, can also appear later in life. It is usually located on the trunk and extremities and appears as variably‐sized papules, patches, or plaques.[3] Pseudo‐Darier’s sign is considered as the characteristic diagnostic clue for congenital smooth muscle hamartoma.[1] Pseudo‐Darier’s sign is a transient piloerection and elevatio...
