BACKGROUND AND PURPOSE The length of large vessel occlusion is considered a major factor for therapy in patients with ischemic stroke. We used 4D-CT angiography evaluation of middle cerebral artery occlusion in prediction of recanalization and favorable clinical outcome and after intravenous thrombolysis (IV-tPA). METHODS In 80 patients treated with(More)
AIM To evaluate the proliferation activity in gliomas using 18F-fluorothymidine (18F-FLT)-positron emission tomography/computed tomography (PET/CT). PATIENTS AND METHODS Samples of 26 tumors were analyzed (mean age=51.6; range=26-72 years; 16 males, 10 females). All examinations were performed using a PET/CT scanner equipped with lutetium oxyorthosilicate(More)
Goblet cell carcinoid (GCC) of the appendix is extremely rare, representing approximately 5% of all primary appendiceal neoplasms. Histologically there are three groups of GCC: group A (typical GCC), adenocarcinoma ex GCC signet ring cell type (group B), and adenocarcinoma ex GCC poorly differentiated carcinoma type (group C), which is the most aggressive.(More)
UNLABELLED Castleman disease is rare diagnosis. It was first mentioned in literature in 1954 by doctor Castleman and Lown. It is rare sickness which primary affects lymfatic nodes. There are four histo-morfologic subtypes and two clinic manifestations (uni and mulicentric). Comon clinical picture is simple lymfadenopathy of neck, medistinal a retroperitonal(More)
Thrombolytic therapy in patients with acute ischemic stroke is contraindicated when the infarction core exceeds a given threshold. To date, there are no standardized guidelines for computed tomography infarction core assessment. Current practice involves use of thresholding methods, where the results are further adjusted by an experienced physician. An(More)
To assess the benefit of 4D-CT angiography (4D-CTA) in determination and precise measurement of middle cerebral artery (MCA) occlusion in comparison to CTA. Possible relationship of measured occlusion lengths with recanalization after intravenous thrombolysis was analysed as a second objective. Detailed evaluation of complete MCA occlusions in 80 patients(More)
INTRODUCTION Tumors of appendix vermiformis are quite rare; they represent only about 0.4% of gastrointestinal tract tumors. They can be both benign and malignant (primary or secondary). Carcinoid is the most common tumor of the appendix. The symptoms can include nothing but non-specific abdominal pain, or on the contrary they can imitate inflammatory acute(More)
BACKGROUND The Non- Hodgkin-lymphoma (NHL) brain infiltration carries a poor prognosis. Because of relatively rare incidence, we decided to share our experience. PATIENTS AND METHODS Retrospective analysis of patients with NHL brain infiltration dia-gnosed in 2001- 2011 at our university hospital. RESULTS Twenty -seven patients with median age of 61(More)
Double gallbladder, a congenital anatomic variation, represents approximately 2% of all congenital anatomic variations of the gastrointestinal tract, its incidence amounting to about 25 in 100 000. It has several types classified according to Boyden's criteria. The diagnostic method of first choice is ultrasonography. When the patient has no health(More)
UNLABELLED Abdominal aortic aneurysm (AAA) is related with higher age and poses a serious threat to the patient´s life. Aneurysms larger than 5.5 cm in diameter are indicated for open or endovascular repair. Giant aneurysms are rarely encountered due to a high risk of rupture. We present a case report of such a giang aneurysm and its open repair. KEY(More)
