Abstract
Introduction and importanceChylothorax is an uncommon complication linked to COVID-19. The fundamental pathophysiology and most effective management strategy are still uncertain. Case presentationA 72-year-old man presented with worsening dyspnea and fatigue one month post-COVID-19. Imaging demonstrated a significant right pleural effusion, with thoracentesis confirming the presence of chylothorax. Despite the implementation of conservative interventions, the effusion remained unresolved. During the right thoracotomy procedure, a 1 cm (about 0.39 in) perforation in proximity to the Azygos vein, encircled by hypertrophic lymph nodes, was identified. Surgical intervention successfully alleviated the symptoms. Clinical discussionThis case implies that mediastinal lymphadenopathy because of COVID-19 could potentially obstruct and interfere with the thoracic duct. This emphasizes the significance of considering chylothorax as a crucial diagnostic possibility in individuals presenting with new onset pleural effusions following COVID-19. Although conservative approaches are typically the first line of management, persistent cases may necessitate surgical intervention to target the root cause. ConclusionsAdditional research is imperative to elucidate the intricate pathways connecting COVID-19 and chylothorax, as well as to ascertain the most effective diagnostic and therapeutic approaches.
