Stenosis of a DVA may result in chronic venous ischemia. We present 6 patients (3 men, 3 women; age range, 30-79 years; mean age, 53 years) with unilateral calcification of the caudate and putamen on noncontrast CT. This calcification typically spared the anterior limb of the internal capsule. No patient presented with symptoms referable to the basal ganglia or had an underlying metabolic disor...

The complete or partial spontaneous regression of large arteriovenous malformations (AVM) is very rare [1-5]. In most cases, a hemorrhagic event or surgical manipulation will have contributed to the thrombosis of the AVM [2, 3]. We report here a patient with large bilateral basal ganglia AVMs who presented with headaches. She was neurologically intact and has remained so for 1 0 years. The pati...

The bulk of spontaneous basal ganglia hemorrhages result from rupture of the small perforating intracerebral arteries and a clinical background of hypertension. Charcot and Bouc hard [1] noted that most microaneurysms occurred in hypertensive brains due to miliary microaneurysms involving branches of lenticu lostriate and thalamoperforating arteries. Such microaneurysms were subsequently demons...

Abstract Lobar cerebral microbleeds (CMBs) and localized non-hemorrhage iron deposits in the basal ganglia have been associated with brain aging, vascular disease neurodegenerative disorders. Particularly, CMBs are small lesions require multiple neuroimaging modalities for accurate detection. Quantitative susceptibility mapping (QSM) derived from vivo magnetic resonance imaging (MRI) is necessa...

BACKGROUND AND PURPOSE During focal cerebral ischemia, the microvascular matrix (ECM), which participates in microvascular integrity, is degraded and lost when neurons are injured. Loss of microvascular basal lamina antigens coincides with rapid expression of select matrix metalloproteinases (MMPs). Plasminogen activators (PAs) may also play a role in ECM degradation by the generation of plasmi...

BACKGROUND AND PURPOSE The aim of our study was to examine surgical practice in the therapy of spontaneous intracerebral hemorrhage in Germany over a period of 10 years. METHODS In 1999 and 2009 a questionnaire with 10 different cases of spontaneous intracerebral hemorrhage was sent to all neurosurgical centers in Germany. It included a cranial CT as well as a case description. The question a...

Patients: 601 patients (mean age 64 y, 57% men) who were conscious, had a computed tomography–confirmed spontaneous lobar ICH (volume 10 to 100 mL) ≤ 1 cm from the cortical surface of the brain, and presented ≤ 48 hours after ictus. Exclusion criteria included hemorrhage that was intraventricular, due to arteriovenous malformation confirmed by angiography or an aneurysm, secondary to tumor or t...
