Purpose: Histopathological differentiation of primary lung cancer is clinically important. We aimed to investigate whether diffusion tensor imaging (DTI) parameters of metastatic brain lesions could predict the histopathological types of the primary lung cancer. Methods: In total, 53 patients with 98 solid metastatic brain lesions of lung cancer we...

Clavicle is the bone that forms anterior border of shoulder arch. It lies on anterosuperior of thorax with first rib. Clavicle is very near to major vascular structures, brachial plexus, esophagus and trachea at thoracic inlet. Because of this, clavicular lesions fractures and sternoclavicular dislocations -especially posterior dislocations- may ca...

Background: Chronic pancreatitis is a progressive inflammatory disease of the pancreatic parenchyma and ductal structures. Typical MR imaging features of chronic pancreatitis include dilatation of the main pancreatic duct and irregularities of branch pancreatic ducts that can be evaluated with MRCP, loss of the normal high signal intensity of the p...

Pulmonary alveolar microlithiasis (PAM) is a rare chronic genetic lung disease in childhood with no proven therapy. It is characterized by the deposition of calcium phosphate microliths within the alveolar air spaces. The effect of disodium etidronate (DE) treatment on PAM is controversial. We report 3 siblings (an 11-year-old boy and 4-year-old tw...

OBJECTIVES: We investigated the relationship between metabolic syndrome and breast arterial calcification detected via mammography in a cohort of postmenopausal subjects. METHODS: Among 837 patients referred to our radiology department for mammographic screening, 310 postmenopausal females (105 patients with and 205 patients without breast arteria...

We describe the demographic, clinic and radiologic features of non-tuberculous cavitary pulmonary diseases in 42 patients with a mean age of 91.1 ± 6.8 months. Infectious etiology was the most common cause (64%), including necrotizing pneumonia (n=15), ruptured hydatid cyst (n=5), lung abscess (n=5) and fungal infection (n=2). Other causes were bro...

The treatment of an acute left main coronary artery occlusion still poses a challenge. In this case report we present a 50-year-old patient with an acute occlusion of the left main artery. After a successful angioplasty without "stenting" due to the complexity of the stenosis the patient underwent a successful bypass surgery. We discuss the therape...

Severe symptomatic aortic stenosis (AS) in a multimorbid 77 year old female was treated with transapical aortic valve implantation with a 23 mm Edwards Sapien valve. Severe valvular regurgitation following implantation, probably due to structural valve failure, was treated successfully with a second valve-in-valve implantation. During a follow-up t...

Computed tomography (CT) and magnetic resonance imaging (MRI) findings for a case of intrahepatic sarcomatoid cholangiocarcinoma is presented. A 48-year-old man with upper abdominal pain underwent contrast-enhanced CT and MRI. A 13 × 10 × 7 cm mass was seen in the left liver lobe, which had hypodense internal architecture on CT and mixed signal int...

Pulmonary nocardiosis is a rare infection and overwhelmingly limited to immunocompromised individuals. Endobronchial nocardiosis is even more rare. Nocardiosis is rarely seen in immunocompetent hosts mostly as cutaneous infection. Here we report an immunocompetent child with endobronchial nocardiosis presenting as nonresolving pneumonia and lung ab...

Transcatheter Aortic Valve Implantation [TAVI] is widespread worldwide as an alternative therapy procedure to the patients suffering from severe aortic valve stenosis. However, we shouldn't forget that the conventional surgical aortic valve replacement is still the gold standard therapy for severe aortic valve stenosis. For the patients who cannot...

In this study, our purpose was to investigate the diagnostic efficacy of the dynamic contrast-enhanced magnetic resonance imaging (MRI) method in the patients with bile duct obstruction. 108 consecutive patients (53 men, 55 women, mean age; 55.77 ± 14.62, range 18-86 years) were included in this study. All the patients underwent conventional upper...

Proteinase inhibitors, isolated from different types of Bauhinia, have an effect on apoptosis, angiogenesis and inflammation. The Bauhinia bauhinioides cruzipain inhibitor (BbCI) is a Kunitz-type inhibitor and inactivates the cysteine proteinases cruzipain and cruzain from Trypanosoma cruzi. Cruzipain and tissue kallikrein have similar biochemical...

Radiofrequency (RF) catheter ablation has been established as an effective and curative treatment for atrial flutter (AFL). Approved methods include a drag-and-drop method, as well as a point-by-point ablation technique. The aim of this study was to compare the acute efficacy and procedural efficiency of a multipolar linear ablation catheter with s...

Objective Recent data suggest that obstructive sleep apnea (OSA) is significantly associated with atrial fibrillation (AF). In the present study, we aimed to investigate the prevalence of AF in a large cohort of OSA patients and to compare the characteristics of patients with vs. without AF. Methods We retrospectively analyzed electrocardiographic...
