Trigeminal Neuralgia and Giant Cell Arteritis
Presentation
Trigeminal Neuralgia and Giant Cell Arteritis are rare causes of headaches, with a rare combination of both diseases occurring on the same patient. While trigeminal neuralgia is a sudden, severe facial pain often described as sharp shooting pain or like having an electric shock in the jaw, gums, or teeth, giant cell arteritis is an inflammation of the lining of the arteritis and often affects the arteritis in the head, especially those in the temples (Alshukry et al., 2017). The illnesses have different clinical presentations in different patients. The clinical manifestations of trigeminal neuralgia include patients presenting with severe, shooting, or jabbing pain that feels like an electric shock. They also have spontaneous attacks of pains or attacks triggered by things. including the face, brushing teeth, or chewing.
Additionally, the patients report experiencing bouts of pain lasting from a few seconds to several minutes. The clinical onset of the illness is predominantly unilateral and is described as electric, focal, lancinating, and sharp pain. On the other hand, giant cell arteritis generally presents as persistent, severe head pain, usually in the temple area of the head. Other manifestations include jaw pain when chewing or opening the mouth wide, scalp tenderness. The onset of the condition can be either insidious or abrupt or begin with constitutional manifestations, including malaise, fever, night sweats, myalgia, and weight loss. The symptoms can occur in a few days and might extend to a few weeks.
Pathophysiology
Giant cell arteritis (GCA) is mainly an illness of cell-mediated immunity, which is considered to arise as a maladaptive response to endothelial injury. With GCA, the lining of the arteries becomes inflamed and causes a swelling that narrows your blood vessels, reducing the amount of blood and vital nutrients and oxygen reaching the body tissues. The while the condition has common complications, including aortic aneurysms and cerebrovascular events in the vertebrobasilar distribution, the most feared complication of GCA is irreversible vision loss However, stroke is an uncommon complication in some GCA patients. The condition's risk factors include age, sex, race and geographic region, polymyalgia rheumatic, and family history GCA affects adults between the ages of 70 and 80 and is uncommon in people below 50 years (Schmidt, 2018). Women are highly susceptible to developing GCA than men and white people in Northern Europe or of Scandinavian descent.
On the other hand, classic trigeminal neuralgia is associated with neurovascular compression in the trigeminal root entry zone, leading to demyelination of voltage-gated sodium channel expression in the membrane (Y & I, 2019). While trigeminal neuralgia usually occurs spontaneously, the condition is sometimes associated with dental procedures or facial trauma. It could result from a blood vessel pressing against the trigeminal nerve, referred to as vascular compression.
Assessment and Diagnosis
The diagnostic assessments of both conditions differ according to the symptoms but include
imaging studies, laboratory tests, and biopsies. The best way to assess and diagnose giant cell arteritis is through a biopsy o
