The coronavirus disease 2019 (COVID-19) outbreak in Wuhan, China has spread rapidly, with confirmed cases currently appearing in multiple countries. Although many details, such as the source of the virus and its ability to spread between individuals, remain unknown, an increasing number of cases have been confirmed to have been caused by human-to-human transmission. 1,2 The primary symptoms of COVID-19 include fever, dry cough, and fatigue. 2 However, some physicians in affected areas have found that some patients diagnosed with COVID-19 have not shown typical respiratory symptoms, such as fever and coughing, at the time of diagnosis; rather, some infected patients have exhibited only neurological symptoms as the initial symptoms, such as the following: (1) headache, languidness, unstable walking, and malaise, which may be due to non-specific manifestations caused by COVID-19 (the proportion of non-specific manifestations as the first symptoms needs to be further explored); (2) cerebral hemorrhage; (3) cerebral infarction; and (4) other neurological diseases. In a recent study of 214 patients with COVID-19, 78 (36.4%) patients had neurological manifestations, such as headache, dizziness, acute cerebrovascular diseases, and impaired consciousness. 3 Of these 214 patients, 40 (18.7%) patients required intensive care unit (ICU) interventions for their severe neurological involvement. 3 Currently, although there have been many cases of patients with COVID-19 complicated by cerebral hemorrhages, relevant studies on this association are lacking. Hence, the physiological relationship between COVID-19 and the incidence of cerebral hemorrhage remains unclear. Based on several lines of evidence, we hypothesize that COVID-19 may involve cranial hemorrhage. First, recent studies have shown that this novel severe acute respiratory syndrome (SARS) coronavirus, SARS-CoV-2, invades human respiratory
