BACKGROUND Thoracic lesions include a variety of benign and malignant lesions of lung, pleura, chest wall and mediastinum. Transthoracic fine needle aspiration cytology (TFNAC) is a well established technique for work up of thoracic lesions. Computed tomography (CT) has extended the use of FNAC, because it is accurate for localization, needle puncture and(More)
PURPOSE The characterization and differentiation of central nervous system (CNS) lymphoma has important diagnostic, therapeutic, and prognostic significance. The purpose of this study is to characterize the diffusion-weighted imaging (DWI) and MR spectroscopic (MRS) findings in CNS lymphoma. MATERIALS AND METHODS Twenty consecutive patients (male [n= 12],(More)
We sought to analyze retrospectively the advantages of coronal and sagittal reformations obtained with multidetector row computed tomography (CT) in patients with acute head trauma. Multidetector 16-section CT was performed in 200 patients (110 male and 90 female; age range, 3-87 years; mean age, 45 years) with acute head trauma. Scans were performed(More)
Virchow-Robin (VR) spaces or perivascular spaces (PVSs) of the brain are pial-lined interstitial fluid-filled structures that accompany penetrating arteries and arterioles for a variable distance as they descend into the cerebral substance. VR spaces can be identified on magnetic resonance (MR) images obtained in patients of all ages in many areas of the(More)
Cavernous angioma of spinal cord is an extremely rare vascular malformation. The association with brain cavernous angioma is even uncommon. There should be a high index of suspicion for a spinal cord lesion whenever a brain cavernous angioma is diagnosed, in cases with appropriate suggestive spinal symptoms. We present a case of cavernous angioma of the(More)
