RESUMEN
Prosopagnosia describes the inability to recognize others by their faces, which may be hereditary or acquired. Acquired cases result from intracranial lesions such as intracranial hemorrhage or ischemia. This case demonstrates acquired prosopagnosia secondary to an intracranial hemorrhage and thus exemplifies the importance of early symptom recognition for appropriate diagnosis and management. A 58-year-old female presented to the emergency department with a chief complaint of the worst headache of her life along with nausea and vomiting. She also reported that she was unable to recognize her children in photos and although she knew her husband was with her, she did not recognize his face. Physical examination revealed no focal motor deficits. Computed tomography angiography of the brain revealed intracerebral hemorrhage of the right occipital lobe. Acquired prosopagnosia can be the only presenting symptom of intracranial pathology. It is most commonly caused by intracranial hemorrhage, as shown in this case report. This demonstrates a unique symptom of posterior circulation strokes that are commonly misdiagnosed in the emergency department.
RESUMEN
INTRODUCTION: Tension hydrothorax is an uncommon emergent condition in which hemodynamic instability and respiratory compromise may occur. Emergency physicians may diagnose tension hydrothorax by point-of-care ultrasound. CASE SERIES: We discuss the key sonographic features assisting in identification. Four patients with history of malignancy who were found to have tension hydrothorax exhibited the following common ultrasound findings: massive, left-sided pleural effusion; complete, compressive atelectasis; and shift of cardiac structures into the right hemithorax, resulting in right-sided probe placement to obtain cardiac views. CONCLUSION: This is the first instance to our knowledge of point-of-care ultrasound findings in tension hydrothorax to be described in the literature.
