Perspective

Vasculitis is a group of diseases characterised by inflammation that destroys blood vessels. Atherosclerosis affects both arteries and veins. Lymphangitis (inflammation of lymphatic vessels) is sometimes thought to be a kind of vacuities. Vasculitis is primarily triggered by leukocyte migration and the damage that results. Although both occur in vasculitis, inflammation of the veins (phlebitis) or arteries (arteritis) are distinct diseases. Cerebral vasculitis is a relatively uncommon cause of juvenile stroke. It can manifest as either primary angiitis of the central nervous system (PACNS) or as a CNS symptom in the context of systemic vasculitis. Headache, stroke, seizures, encephalopathy, and symptoms of a systemic inflammatory condition are all clinical markers of vasculitis. Cerebral vasculitis (also known as angiitis) is a type of vasculitis (inflammation of the blood vessel wall) that affects the brain and occasionally the spinal cord [1]. It affects all blood vessels, whether they are very small (capillaries), mediumsized (arterioles and venules), or huge (arteries and veins). When blood flow in a vasculitis-infected vessel is diminished or interrupted, the organs that receive blood from that channel begin to perish. It can cause a variety of neurological symptoms, including headaches, skin rashes, fatigue, joint pains, trouble moving or coordinating parts of the body, changes in sensation, and changes in perception, thinking, or behaviour, as well as the phenomenon of a mass lesion in the brain. If there is no underlying cause, angiitis/vasculitis of the central nervous system (PACNS) is termed to be "primary [2]." The specific mechanism of the underlying disease is unknown; however autoimmunity is the fundamental mechanism of all vasculatures [3].

Infections, systemic auto-immune diseases such as systemic lupus erythematous (SLE) and rheumatoid arthritis, medications and drugs (amphetamine, cocaine, and heroin), some cancers (lymphomas, leukaemia, and lung cancer), and other forms of systemic vasculitis such as granulomatosis with polyangiitis or polyarteritis nodosa. Cerebral angiitis is a relatively uncommon cause of stroke, headache, encephalopathy, and seizures. Multi-locular lesions on magnetic resonance imaging (MRI), inflammatory laboratory findings in stroke patients, or intracranial stenosis detected in computed tomography angiography (CTA), MRA, or angiography all raise the possibility of cerebral vasculitis, but none of these findings is reliable enough to allow a definite diagnosis [4]. The first and most crucial phase in the diagnostic work-up is a complete anamnesis and clinical examination, which includes questions about drug addiction, previous medical disorders, and symptom characterization, particularly headaches. The exact reason is unknown in most cases, but the immune system (which helps keep the body healthy) plays a part. While the immune system's primary function is to protect the body, it can occasionally become "overactive" and attack the body. In the majority of cases of vasculitis, something triggers an immunological or "allergic" response in the blood vessel walls’ person's medical history, symptoms, a full physical examination, and the findings of particular laboratory testing are used to make a diagnosis of vasculitis, including CNS vasculitis. Other procedures that may be performed include X-rays, tissue biopsies (the removal of a sample of tissue for examination under a microscope), and blood vessel scans. A provider may also do a lumbar puncture or spinal tap to check the spinal fluid to determine what is causing the inflammation. This test is frequently used to diagnose CNS vasculitis. Other important tests include magnetic resonance imaging (MRI), computed tomography (CT), and a cerebral angiography. An angiography can reveal which blood arteries are constricted. Because other illnesses can produce some of the same brain artery abnormalities as CNS vasculitis, a brain biopsy is the only way to be sure. A brain biopsy can identify CNS vasculitis from other disorders with similar symptoms. Behest’s illness is a multisystem, chronic-relapsing vasculitis that mostly affects the venous system. This uncommon condition is more common in Turkish and Far Eastern patients [5].

The International Study Group for Behçet's disease diagnostic criteria for oculo-mucocutaneous disease include recurrent oral ulcerations with at least two of the following: recurrent genital ulceration, eye lesions (uveitis, cells in the vitreous on slitlamp examination, or retinal vasculitis), skin lesions (erythema nodosum), or a positive pathergy test result. 20% of individuals with neuro-Behçet have intracranial sinus or venous thrombosis with pseudotumor cerebri [6]. In Behçet illness, a skin or brain biopsy is typically unnecessary; however, it is critical to rule out alternative explanations of neurological symptoms. RCVS, intracranial atherosclerosis, Moyamoya disease, autoimmune encephalopathy’s, and viral illnesses such as varicella zoster virus (VZV) vasculopathies or endocarditis are also important differential diagnosis. Because the majority of these disorders mirror MRI, digital subtraction angiography (DSA), and laboratory findings of angiitis, a sample of afflicted tissue is frequently required to confirm the right diagnosis.
