Boerhaave Syndrome Presenting Black Pleural Effusion: A Case Report

A 55-year-old man experienced nausea and vomiting after brushing his teeth. He experienced back pain after this episode and visited our emergency department. Chest computed tomography (CT) images revealed moderate pleural fluid accumulation and mild left pneumothorax. Thoracentesis showed black pleural effusion. Thoracic drainage included food debris with black pleural effusion, and gastroscopy revealed food debris and perforation of the lower esophagus. Esophageal perforation was surgically repaired using omental implantation and pleuroclysis. Given the high mortality rate associated with black pleural effusion, prompt diagnostic procedures and corresponding management are essential.
