Monckeberg's Medial Sclerosis as a Cause for Headache and Facial Pain

Giant Cell Arteritis: A Case-Based Narrative Review of the Literature

Purpose of Review

Giant cell arteritis (GCA) is a chronic, inflammatory condition, primarily affecting the medium and larger arteries. The purpose of this narrative review is to describe GCA in the context of headache and facial pain, based on a case and the available current literature. Understanding the etiology, pathophysiology, the associated conditions, and the differential diagnoses is important in managing GCA.

Recent Findings

In a patient presenting with unilateral facial/head pain with disturbances of vision, GCA should be considered in the differential diagnosis. There is an association of GCA with several comorbid conditions, and infections including coronavirus-19 (COVID-19) infection. Management of GCA primarily depends upon the identification of the affected artery and prompt treatment. Permanent visual loss and other serious complications are associated with GCA.

Summary

GCA is characterized by robust inflammation of large- and medium-sized arteries and marked elevation of systemic mediators of inflammation. An interdisciplinary approach of management involving the pertinent specialties is strongly recommended.

Occult Mönckeberg medial calcinosis of the facial and infraorbital arteries in an elderly edentulous patient

Mönckeberg medial calcinosis (MMC) is a potentially serious vasculopathy involving calcification of the arterial tunica media of the extremities, heart, and other viscera. There are a limited number of cases reported in the dental literature, usually associated with the facial artery. Although MMC is often discerned as an occult radiologic finding in middle-aged adults, its presence may serve as a harbinger for end-stage renal disease, diabetes, other pathologic processes, and possible regional hypoperfusion. The objective of this report is to feature an elderly patient with MMC of the facial and infraorbital arteries. In addition, a brief review of published cases of MMC and its differential diagnosis have been provided. It is recommended that affected patients be referred for a comprehensive medical assessment. Timely discovery of calcified arteries may improve patient outcomes.

Cranial giant cell arteritis mimickers: A masquerade to unveil

Giant cell arteritis (GCA) is a large-vessel vasculitis that affects cranial and extra-cranial arteries. Extra-cranial GCA presents mainly with non-specific symptoms and the differential diagnosis is very broad, while the cranial form has more typical clinical picture and physicians have a lower threshold for diagnosis and treatment. Although temporal artery biopsy (TAB) has an established role, ultrasound (US) is being increasingly used as the first-line imaging modality in suspected GCA. Vasculitides (especially ANCA-associated), hematological disorders (mainly amyloidosis), neoplasms, infections, atherosclerosis and local disorders can affect the temporal arteries or might mimic the symptoms of cranial GCA and produce US and TAB findings that resemble those of temporal vasculitis. Given that prompt diagnosis is essential and proper treatment varies significantly among these diseases, in this review we aimed to collectively present disorders that can masquerade cranial GCA.
