17 Possible Causes for Cerebrospinal Fluid Abnormality, Frontal Intermittent Rhythmic Delta Activity, Papilledema

  • Cerebral Hemorrhage

    Hypertensive encephalopathy (HE) is a syndrome characterized by severe headache, nausea and vomiting, papilledema, visual disturbances, seizures, confusion, and in severe[] Cerebrospinal fluid (CSF) studies disclosed mononuclear pleocytosis with elevated protein levels.[] Results of a polymerase chain reaction assay of the cerebrospinal fluid were positive for HSV-1. His course was complicated by 2 episodes of cerebral hemorrhage.[]

  • Subarachnoid Hemorrhage

    […] the pathogenesis of the disease remains controversial, recent case series of transverse sinus stenting have reported very high rates of symptom response and resolution of papilledema[] […] for SAH; CT negative for SAH and inconclusive cerebrospinal fluid examination.[] […] with severe, sudden headache and CN III palsy Evaluation Immediate head CT without contrast to look for blood in the subarachnoid space If CT is negative, and there is no papilledema[]

  • Brain Neoplasm

    Findings may include the following: Papilledema, which is more prevalent with pediatric brain tumors, reflects an increase in intracranial pressure (ICP) of several days or[] For example, blood and cerebrospinal fluid may also be tested to check for substances secreted by tumors (called tumor markers) and for gene abnormalities that are characteristic[] 3 months; new parictal lesion. deficits and with mass effect abnormalities; Dx: MS BAEP Brain stem auditory evoked potential, CC corpus callosum, CSF cerebrospinal fluid,[]

  • Subdural Hematoma

    Ophthalmological examination was performed in 238 patients, and papilledema was identified in only one patient (0.4%).[] Neurological examination revealed bilateral papilledema and bilateral sixth nerve palsies.[] Papilledema is indicative of increased ICP, but is found less commonly in geriatric patients since any underlying brain atrophy can accommodate a large expanding mass before[]

  • Neurosyphilis

    Patients can have disc edema without visual compromise, which has been attributed to papilledema from raised intracranial pressure or optic perineuritis from optic nerve sheath[] A diagnosis of neurosyphilis should be considered in patients with serologic evidence of syphilis and one or more of the following cerebrospinal fluid abnormalities; mononuclear[] T hey divided the series into three forms: syphilitic hydrocephalus, 26 cases, with a syndrome of acutely increased CSF pressure and papilledema; syphilitic meningitis of[]

  • Stroke

    In most cases, it occurs in a rhythmic and intermittent manner, and the most commonly and important types are frontal intermittent rhythmic delta activity (FIRDA) ( Fig 2[] Frontal intermittent rhythmic delta activity (FIRDA) in pituitary adenoma. Clin Electroencephalogr 1995;26:173-179. [ Links ] 29.[] ), occipital intermittent rhythmic delta activity (OIRDA) and temporal intermittent rhythmic delta activity (TIRDA) ( Fig 3 ).[]

  • Cerebral Neoplasm

    The diagnosis of a brain tumor first depended on recognition of the triad—headache, nausea and vomiting, and papilledema.[] This is a sac of cerebrospinal fluid (CSF), which has been "trapped" outside or inside the brain. It might also be called a "leptomeningeal cyst."[] Papilledema is also rare because it manifests late in thecourse of the tumor.[]

  • Susac Syndrome

    […] and amaurosis fugax; acute optic neuropathy complicating multiple sclerosis, neuromyelitis optica spectrum disorder, Leber hereditary optic neuropathy, and Susac syndrome; papilledema[] Cerebrospinal fluid was abnormal in 5 patients showing pleocytosis (mean, 24.6; range, 6-85 cells/mL) and elevated protein level (mean, 210; range, 113-365 mg/dL).[] The EEG showed frontal intermittent rhythmic delta activity.[]

  • Metabolic Encephalopathy

    Focal neurologic abnormalities (eg, cranial nerve palsies, motor or sensory deficits) or papilledema suggests a structural CNS disorder.[] The cerebrospinal fluid can also be analyzed for abnormal proteins, chemicals, and cells.[] […] patterns, e.g., frontal intermittent rhythmic delta activity (FIRDA), or spikes and sharp waves as well as spike-wave discharges in temporal regions. [37] In hyponatremia[]

  • Glioma

    This swelling — papilledema — is a sign that requires immediate medical attention.[] fluid obstruction or brain stem dysfunction such as cranial nerve abnormalities, ataxia and long tract signs developing over a short period of time ( Front Oncol 2012;2:205[] […] buildup of cerebrospinal fluid placing pressure on the brain.[]
