Eagle syndrome (ES) is a rare clinical syndrome characterized by the elongation of the temporal bone's styloid process, or calcification of stylohyoid ligament, compressing surrounding structures causing pharyngalgia. One of its variants, the styloid-carotid artery syndrome, produces symptoms by compression of the external or internal carotid arteries (ICA). Here, we present a case of a 43-year-old woman with ES and bilateral ICA dissections. The patient underwent staged bilateral angioplasty and covered stent placement, followed by styloidectomy. A computerized tomography angiogram revealed patency of both stents at a two-year follow-up.
Autoimmune encephalopathy is one of the treatable causes of rapidly progressive dementia; however, it is often underdiagnosed. Autoantibodies against voltage-gated calcium channel (VGCC) have been linked to several neurological disorders, including Lambert-Eaton syndrome, but VGCC antibody-associated encephalopathy is uncommon. Herein, we present a case of a 74-year-old woman with prominent neuropsychiatric symptoms followed by rapid cognitive decline. Extensive initial studies were nondiagnostic. Subsequently, serum N-type VGCC antibody was positive. After treatment with intravenous immunoglobulin, the patient's cognition and neuropsychiatric symptoms significantly improved.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
