چکیده

We report a patient with multiple simultaneous embolic infarctions with localized hemorrhagic conversion. A 75-year-old male patient had several silent microbleeds (SMBs) exclusively in the cerebral cortex, and underwent angioplasty and stenting for bilateral carotid stenosis. He subsequently experienced embolic infarctions in the cortex and the striatum: the cortical infarction, where an SMB had been present, showed hemorrhagic conversion, whereas the striatal infarction did not. This case suggests that SMBs are indicators of an underlying hemorrhage-prone state.

Incidence, locations, and longitudinal course of silent microbleeds in moyamoya disease: a prospective T2*-weighted MRI study.

BACKGROUND AND PURPOSE Clinical significance of silent microbleeds is unknown in moyamoya disease. This study was aimed to clarify the incidence, locations, and longitudinal course. METHODS This prospective cohort study included 78 nontreated patients with moyamoya disease. The incidence and locations of silent microbleeds were evaluated on T2*-weighted MRI. MR examinations were repeated ever...

The clinical spectrum of hemorrhagic infarction.

The hospital records and head CT scans of 44 patients with hemorrhagic infarction were retrospectively analyzed. The majority of cases (73%) were embolic or possibly embolic in etiology, and 55% were not associated with anticoagulant therapy. Adverse prognosis was most clearly related to infarct size, underlying systemic illness, and symptomatic hemorrhage. Of the nineteen patients in whom seri...

Silent New Brain Lesions: Innocent Bystander or Guilty Party?

With the advances in magnetic resonance imaging, previously unrecognized small brain lesions, which are mostly asymptomatic, have been increasingly detected. Diffusion-weighted imaging can identify small ischemic strokes, while gradient echo T2* imaging and susceptibility-weighted imaging can reveal tiny hemorrhagic strokes (microbleeds). In this article, we review silent brain lesions appearin...

The Presence of Previous Cerebral Microbleeds Has a Negative Effect on Hypertensive Intracerebral Hemorrhage Recovery

Background and Purpose: Cerebral microbleeds are an intracerebral microangiopathy with bleeding tendency found in intracerebral hemorrhage patients. However, studies about cerebral microbleed effects on the prognosis of hypertensive intracerebral hemorrhage patients are rare. We performed a prospective study to discuss not only the risk factors of cerebral microbleed incidence in hypertensive i...

Embolic Stroke, Atrial Fibrillation, and Microbleeds

Patients with AF have a high risk of ischemic stroke, which can be dramatically reduced by oral anticoagulation with vitamin K antagonists (VKAs). I will look at our patient from different positions. First, the patient has paroxysmal AF. The type of AF (paroxysmal, persistent, or permanent) has only a minor impact on the stroke risk. All types of AF respond to oral anticoagulation with VKAs or ...
