Discussion: A large part of both clinical and subclinical lesions found in our daily work are benign and correspond with fibrocystic changes (FCC). This entity is complex and part exhibit traits that define characteristically in MRI and diagnose correctly, but there is another small group of changes that can take the image aspect of cancer. From a complex case, we review the main aspects of the...
Behçet’s disease is a multisystem vasculitis. Its neurological involvement mostly includes parenchymal and non-parenchymal central nervous system manifestations. Peripheral nervous system presentations are rare. A 32-yr-old male patient who fulfilled the international study group criteria for Behçet’s disease, referred to our center with walking difficulty and repeated falling downs. Neurologi...
Receptor-dependent uptake mechanisms for low-density lipoprotein (LDL) were studied in rabbit liver parenchymal and non-parenchymal cells. Hybridization studies with a cDNA probe revealed that mRNA for the apo (apolipoprotein) B,E receptor was present in endothelial and Kupffer cells as well as in parenchymal cells. By ligand-blotting experiments we showed that apo B,E-receptor protein was pres...
BACKGROUND AND PURPOSE Progressive multifocal leukoencephalopathy (PML) is typically occult at angiography and fails to enhance on MR images. After observing angiographic abnormalities characterized by arteriovenous shunting and pathologic parenchymal blush in patients with AIDS-related PML, often in the absence of contrast enhancement on MR images, we hypothesized that there might be distinct ...
BACKGROUND AND PURPOSE Brain enhancement on contrast-enhanced T1-weighted imaging (CET1-WI) after ischemic stroke is generally accepted as an indicator of the blood-brain barrier disruption. However, this phenomenon usually starts to become visible at the subacute phase. The purpose of this study was to evaluate the time-course profiles of K(trans), cerebral blood volume (vp), and CET1-WI with ...
