PRIMARY cerebral amyloidosis is characterized by deposition of amyloid within the cerebral tissue (e.g., core of neuritic plaques and core of plaques in spongiform encephalopathies) and the cerebral and meningeal blood vessel walls (amyloid or congophilic angiopathy) in the absence of systemic amyloidosis. Primary cerebral amyloidosis has been associated with normal brain aging changes" and wit...

OBJECTIVE AND IMPORTANCE To describe successful endoluminal revascularization of an acute M1 occlusion 4 days after craniotomy and tumor resection. CLINICAL PRESENTATION A 16-year-old right-handed girl presented with a 1-month history of daily headaches. The neurological examination was normal. Magnetic resonance imaging and computed tomography demonstrated a mass consistent with an epidermoi...

Cerebral amyloid angiopathy is a pathologic condition characterized by the deposition of amyloid in the walls of small vessels in the cerebral cortex and meninges. Intracerebral hemorrhage is common in persons with this condition, but pure subarachnoid or subdural hemorrhage is rarely seen. Recently, the existence of two types of amyloid proteins related to cerebral amyloid angiopathy, beta pro...

The sequential changes in systemic and cerebral hemodynamics, systemic and cerebral oxygen transport and consumption rates, and the regional blood flows (measured with 15 micron microspheres) to the cortical and subcortical brain tissues were determined in nine dogs subjected to graded hemorrhage (10 ml/kg X 4 at 15 min intervals). As hemorrhage progressed, both mean arterial pressure and cardi...

Background and Purpose—The incidence of hemorrhage after combined intravenous (IV) and intra-arterial (IA) recombinant tissue plasminogen activator (rt-PA) was examined in patients entered into the Interventional Management of Stroke (IMS) trial. We also analyzed factors predicting symptomatic and asymptomatic intracerebral hemorrhage (ICH). Methods—The IMS study treated patients within 3 hours...

Intracerebral hemorrhage in patients with moyamoya disease is rare in children. We report three unique cases of pediatric moyamoya disease with hemorrhagic onset. Two 7-year-old girls and a 9-year-old girl were admitted to our hospital because of intracerebral hemorrhage associated with angiographically verified moyamoya disease. Two of them did not demonstrate either an ischemic episode or cer...

Segmental arterial mediolysis (SAM) is a presumably vasospastic disorder [1]. SAM commonly involves large to medium sized intraabdominal, cerebral and rarely coronary arteries. In 1943, Kernohan and Woltman described arteries with features of SAM in the posterior circulation of the brain for the first time [2]. The first case of SAM was presented in 1976 by Slavin and Gonzalez [3]. At first the...

Spontaneous spinal hemorrhage is a rare condition. We present a case in which the diagnosis was complicated by a concomitant intra-abdominal hemorrhage. The patient, taking coumarins, presented with acute back pain and abdominal pain and progressive paresis of the lower limbs. Computed tomography angiography of the abdomen showed an intra-abdominal hemorrhage and an aneurysm of the celiac trunk...
