Background. COVID-19 is a disease caused by a new strain of coronavirus (SARS-COVID-19). e WHO first learned about this new virus on December 31, 2019, following a report on a group of cases of “viral pneumonia” in Wuhan, People’s Republic of China, and declared a pandemic in March 2020. e disease was an almost complete unknown at the outset, but knowledge of its pathophysiology, clinical picture, and treatment options grew and developed rapidly. Objective. Dizziness is a very common symptom that patients report in routine clinical practice and one of the significant clinical manifestations of COVID-19. is short report investigated a possible connection between COVID-19 and benign paroxysmal positional vertigo (BPPV). Methods. We present two cases of benign paroxysmal positional vertigo (BPPV), which developed within two weeks of SARS-COVID-19 infection, manifesting with mild disease severity in early November 2020. Results. In both cases, the disease manifested by severe, short-lived attacks of vertigo, objective-circular type, with accompanying nausea and vomiting. e symptoms occurred when lying in bed and turning to the right and assuming an upright position. e diagnosis of posterior semicircular canal BPPV (PC- BPPV) was made based on a subjectively and objectively positive right-sided Dix–Hallpike test. Conclusions. e pathophysiology of post-COVID BPPV is probably similar to that of other viral infections, with some of its specificities such as inducing hypercoagulation and microthrombus formation, which can cause significant circulatory disorders possibly affecting its pathogenesis. 1.Introduction Coronavirus disease-19 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-COVID- 19). e WHO declared a pandemic of this virus in March 2020 after its rapid spread from the city of Wuhan, in the province of Hubei in China [1]. It has been shown that, in addition to the most common clinical symptoms of the disease, such as dry cough, fever, and general weakness, some patients develop taste and smell disorders, headaches, congestion of the nasal mucosa, gastrointestinal disorders, and dizziness. A small proportion of patients may develop significant complications such as bilateral pneumonia, ac- companied by shortness of breath, chest pain, and a characteristic finding of ground-glass opacity on CT, which indicates severe viral pneumonia [2, 3]. e infection can affect the central nervous system, and neurological symptoms can appear both in the initial disease stages and in the protracted recovery period. Most patients experience, to a greater or lesser extent, neurological and psychological symptoms, ranging from insomnia, anxiety, and depression to disturbances of consciousness, confusion, and epileptic seizures. Among neurological complications, the most common are encephalopathy and cerebrovascular stroke, disorders of consciousness, seizures, and hypoxic brain injuries. Dys- osmia and dysgeusia and nonspecific symptoms such as headache, dizziness, and paresthesia have been reported.
