Insights

Familial Mediterranean fever (FMF), a genetic autoinflammatory disease, can rarely cause central nervous system vasculitis. This case study highlights FMF-associated vasculitis leading to brain stem infarction in a young patient.

Area of Science:

  • Genetics
  • Immunology
  • Neurology

Background:

  • Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disorder caused by MEFV gene mutations.
  • FMF typically presents with recurrent fever and polyserositis, with rare neurological manifestations.
  • Systemic vasculitis associations with FMF, including Henoch-Schönlein purpura and Behçet's disease, are documented.

Observation:

  • A young patient with genetically confirmed FMF experienced a brain stem infarction during a typical FMF attack.
  • Diagnostic workup included cerebrospinal fluid analysis, angiography, and leptomeningeal biopsy.
  • Neurological manifestations of FMF are rare and poorly understood.

Findings:

  • The patient's stroke was attributed to FMF-associated central nervous system vasculitis.
  • This represents a rare but serious complication of Familial Mediterranean fever.
  • The study details the diagnostic process for identifying CNS vasculitis in FMF.

Implications:

  • Highlights a rare but critical neurological complication of FMF.
  • Suggests the need for heightened awareness of CNS vasculitis in FMF patients presenting with neurological symptoms.
  • Warrants further research into the pathophysiology and therapeutic strategies for FMF-associated CNS vasculitis.

Encephalitis l: Introduction

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...

Encephalitis ll: Pathophysiology

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 Meningitis01:18

Viral Meningitis

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...
Arboviral Encephalitis01:25

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
Hemorrhagic Stroke ll: Pathophysiology01:29

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
