Summary
Oligodendroglial gliomatosis cerebri (OGC) can mimic transient ischemic attacks (TIAs). This rare brain tumor requires broad differential diagnosis for episodic neurological symptoms, confirmed via advanced imaging and biopsy.
Area of Science:
- Neuro-oncology
- Neurology
- Diagnostic Imaging
Background:
- Transient neurological dysfunction necessitates a broad differential diagnosis, considering common causes like TIA, seizures, and migraines.
- Uncommon causes, including brain tumors, can also present with transient neurological symptoms, complicating diagnosis.
- Oligodendroglial gliomatosis cerebri (OGC) is a rare diffuse brain tumor that can manifest with episodic neurological deficits.
Purpose of the Study:
- To present a case of oligodendroglial gliomatosis cerebri (OGC) with an unusual TIA-like presentation.
- To highlight the diagnostic challenges and utility of advanced neuroimaging in identifying OGC.
- To discuss the clinical and radiological features of OGC.
Main Methods:
- Case presentation of a 68-year-old male with TIA-like symptoms.
- Brain magnetic resonance imaging (MRI) to identify diffuse white and gray matter abnormalities.
- Magnetic resonance spectroscopy (MRS) to assess the metabolic profile suggestive of OGC.
- Histopathological and molecular genetic analysis of brain biopsy tissue for definitive diagnosis.
Main Results:
- The patient presented with transient neurological symptoms mimicking a TIA.
- MRI revealed multiple diffuse T2 hyperintensities in both white and gray matter.
- MRS findings were suggestive of gliomatosis cerebri.
- Histopathology and molecular studies confirmed the diagnosis of OGC.
Conclusions:
- Oligodendroglial gliomatosis cerebri (OGC) can present with atypical TIA-like symptoms, emphasizing the need for comprehensive diagnostic evaluation.
- Advanced neuroimaging techniques, including MRI and MRS, play a crucial role in the early detection and characterization of OGC.
- This case underscores the importance of considering rare brain tumors in the differential diagnosis of episodic neurological dysfunction.

01:26Transient Ischemic Attack l: Introduction
14
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...

01:29Hepatic Encephalopathy
33
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic...

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.

01:19Encephalitis l: Introduction
11
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

01:26Encephalitis ll: Pathophysiology
18
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
