The Visualization and Frequency of Cerebral Cavernous Angioma on Magnetic Resonance.

Background: Cavernous angiomas (CAs) are abnormal, congenital, vascular malformations, which often grow in size over the course of life. Conservative treatment, microsurgical resection, and stereotactic radiosurgery are the three main options for treatment of CA. Radiological studies play a key role in diagnosis, with magnetic resonance (MR) being the method of choice.

Symmetry, asymmetry and hypoplasia of the intracranial internal carotid artery on magnetic resonance angiography.

Objective: The aim of this study was to determine the prevalence of symmetry, asymmetry and hypoplasia of the intracranial internal carotid artery (ICA), and the possible presence of other variants of the ICA by magnetic resonance angiography (MRA).

Subjects And Methods: This prospective-retrospective study included 1000 subjects who underwent consecutively MRA of the cerebral arteries. 3D-time of flight angiograms were performed according to the standard protocol.

Tumor marker CA 15-3 in breast cancer patients.

Objective: The aim of this study was to determine whether there is a correlation between the serum concentration of the tumor marker CA 15-3 and breast cancer, which has not been proven by the existence of regional and distant metastases, and breast cancer with the presence of regional and distant metastases.

Patients And Methods: The study was a retrospective-prospective study, and was conducted on 100 women aged 40-70 years of age in the period of January 2007 until June 2011, in whom, after surgery, breast cancer was histologically verified, where before the surgery serum tumor marker CA 15-3 levels were established. The serum tumor marker CA 15-3 concentrations are determined in all patients after radiological diagnosis of suspected breast cancer (radiological findings concluded as BI RADS 4 and 5).

Anton's Syndrome due to Bilateral Ischemic Occipital Lobe Strokes.

We present a case of a patient with Anton's syndrome (i.e., visual anosognosia with confabulations), who developed bilateral occipital lobe infarct.

Wegener's granulomatosis of the paranasal sinuses with orbital and central nervous system involvement-diagnostic imaging.

Wegener's granulomatosis (WG) is a systemic vasculitis that can affect any organic system, but primarily involves the upper and lower respiratory tracts and the kidneys. WG relatively frequently affects the nervous system (in 30-50%), usually in the form of peripheral or cranial neuropathy. Involvement of the brain is reported in a very small percentage of patients (2%-8%).
