While primarily a respiratory illness, infection with the novel coronavirus (COVID-19) is associated with pathologic changes in coagulation, characterized by both thromboembolic and bleeding events. We present the case of a 22-year-old female diagnosed with renal angiomyolipoma (AML) rupture 2 weeks after COVID-19 infection, ultimately requiring admission for hemorrhage control via endovascular embolization. Emergency medicine physicians should maintain a high index of suspicion for renal AML rupture and other spontaneous bleeding events in patients with recent COVID-19 infection due to a possible correlation between the two.

Concussions and chronic traumatic encephalopathy (CTE) related to professional football has received much attention within emergency care and sports medicine. Research suggests that some of this may be due to a greater likelihood of initial helmet contact (IHC), however this association has not been studied across all age groups. This study aims to investigate the association between player age and IHC in American football. ⋯ There is a high rate of IHC with a lower relative risk of IHC at most levels of play compared to the NFL. Further research is necessary to determine the impact of IHC; the high rates across all age groups suggests an important role for education and prevention.

Case Reports
Central neurogenic hyperventilation secondary to suspected metastatic renal cell carcinoma.
Central neurogenic hyperventilation (CNH) is a neurogenic disorder rarely described within Emergency Medicine literature. CNH is a primary cause of hyperventilation, most commonly due to primary central nervous system neoplasms. Patient presentation varies based on the underlying cause, and may present with a sole chief complaint of dyspnea. ⋯ While the cause of the patient's hemorrhage was not elucidated, given the patient's widely metastatic disease, it was presumed to be secondary to metastasis. Our case highlights both a unique cause of a rare disorder of hyperventilation, and a diagnostic challenge to the emergency medicine provider. It is important to consider central causes of hyperventilation in patients with dyspnea and neurologic symptoms.

Cardiac hemangiomas are exceedingly rare and can lead to cardiac tamponade. Cardiac tamponade is a true medical emergency that can cause cardiovascular collapse and death if not managed appropriately. ⋯ For patients with cardiac tumors causing tamponade, emergent pericardiocentesis and cardiovascular surgery consultation are necessary in management. We present a unique case of cardiac tamponade caused by a cardiac hemangioma.
