Introduction: Cerebrovascular incidents are considered uncommon but important complications of vaccination against coronavirus disease-2019 (COVID-19). Subarachnoid hemorrhages (SAH) usually occur due to an underlying cerebral aneurysm. In this study, we have reported a subarachnoid hemorrhage incidence in a patient shortly after receiving the COVID-19 vaccine (ChAdOx1-AstraZeneca). Case Presentation: The patient was a 69-year-old male with no remarkable risk factors, referred to the emergency room with complaints of headache, nausea, and vomiting. The patient had received his first dose of vaccine against COVID-19 four days before symptoms started. An aggravated headache, nausea, elevated blood pressure (180/100), and drowsiness occurred on the second day of admission. Imaging from head computed tomographic (CT) scans implied acute hydrocephalus and increased intracranial pressure (ICP) caused by subarachnoid hemorrhage. The condition was treated by inserting an external ventricular drain (EVD), removed after one week, and the patient was discharged with no permanent deficit. We found no underlying vascular abnormality in primary and follow-up cerebral angiographies. Conclusions: There are reports of cerebral hemorrhages caused by COVID-19 vaccination, mostly intra-parenchymal. Our study observed a type of cerebrovascular event that has not been reported frequently. Vaccine-associated cerebrovascular events, however rarely, are critical. It is important to demonstrate possible risks and complications, as vaccination programs against COVID-19 have become an essential part of health care in most countries.

Introduction: Spontaneous hemopneumothorax is an unusual complication of pneumonia caused by COVID-19. This study presents a rare case of hemopneumothorax caused by COVID-19. Case Presentation: A 21-year-old man with no medical or surgical history was visited with left shoulder pain. For two days, he suffered from increased pain in his left shoulder, which extended to his neck and back, and he was unable to lean forward. He had no history of chest trauma and no symptoms such as fever, cough, or gastrointestinal symptoms. After the visit, a chest X-ray (CXR) was ordered, and he was admitted with a diagnosis of pneumothorax. A PCR test was performed on the patient that was positive. Conclusions: The patient's pathophysiology of spontaneous Hemopneumothorax disease was unknown. While this is an uncommon complication, spontaneous hemopneumothorax has life-threatening effects at the top of the list of respiratory complications associated with COVID-19.
