Prothrombotic conditions are known risk factors for porencephalic cyst formation and cerebral vein thrombosis. Intracerebral hemorrhage is a potential complication of a cerebral vein thrombosis. Porencephaly is a risk factor for intracerebral hemorrhage and cerebral vein thrombosis formation. We
A 61-year-old man presented with coma and left hemiparesis. He was found to have tonic downward and inward deviation of the right eye, and a right lateral gaze palsy. He also had occasional downward bobbing movements of the right eye, and a partial bilateral upgaze paresis. CT showed a right pontine
OBJECTIVE
Tonic-clonic activity (TCA) at onset complicates 3% to 21% of cases of subarachnoid hemorrhage (SAH). The impact of onset TCA on in-hospital complications, including seizures, remains unclear. One study associated onset TCA with poor clinical outcome at 6 weeks after SAH, but to our
We present a 46-year-old man who developed repetitive focal tonic-clonic seizure-like involuntary movement in the left lower extremity after a left basal ganglia (BG) hemorrhage. His symptoms were induced only by voluntary movement of the left lower extremity and were followed by transient
Epidermoid cysts account for approximately 1% of all intracranial tumors. Hemorrhage into an epidermoid cyst is extremely rare, and has only been reported a few times. To our knowledge, there are no reports of a hemorrhagic epidermoid cyst presenting with a first generalized tonic clonic seizure. We
OBJECTIVE
Acute ethanol intoxication (AEI) attenuates the arginine vasopressin (AVP) response to hemorrhage leading to impaired hemodynamic counter-regulation and accentuated hemodynamic stability. Previously we identified that the ethanol-induced impairment of circulating AVP concentrations in
BACKGROUND
A 33-year-old woman experienced a thunderclap headache immediately postpartum. The headache recurred over the next 10 days, and the patient also developed generalized tonic-clonic seizures. A subarachnoid hemorrhage was demonstrated on a head CT scan.
METHODS
Physical examination,
The protein kinase C (PKC) and calmodulin systems each play a role in vascular contraction. However, the correlation of these two systems in producing contraction has been unclear. To clarify the pathophysiology of vasospasm after subarachnoid hemorrhage, the authors demonstrated tonic contraction
Dengue is a common viral infection worldwide with presentation varying from clinically silent infection to dengue fever, dengue hemorrhagic fever, and severe fulminant dengue shock syndrome. Neurological manifestation usually results from multisystem dysfunction secondary to vascular leak.
Cerebral vasospasm following subarachnoid hemorrhage was induced in the squirrel monkey in order to evaluate the involvement of cerebrovascular sensory nerves in the development of the vasospasm. A unilateral surgical section of the trigeminal nerve at post- but not at pre-Gasserian level caused
The aim of the present study was to investigate the changes of lymphatic contraction after hemorrhagic shock in vitro and the underlying role of nitric oxide (NO). Rat thoracic duct segments were isolated at 0, 0.5, 1, 2 and 3 h after hemorrhagic shock. Using Pressure Myograph System, we determined
Dengue fever has been a major cause of morbidity and mortality in subtropical and tropical countries. We report a rare case of severe dengue with spontaneous intracranial hemorrhage. A search of literature through PubMed revealed that the largest series analyzed so far only included five cases. A
Hemorrhage in the midbrain and/or pons in patients is often associated with increased metabolism, resulting in hyperthermia. We have recently reported that hyperthermia develops in anesthetized rats following prepontine knife-cuts or procaine microinjections into the midbrain or upper pontine
