SESSION TITLE Problems in the Pleura Case Posters 2 SESSION TYPE Case Report Posters PRESENTED ON 10/17/2022 1215 pm - 0115 pm INTRODUCTION: Hematologic malignancies can often be complicated by pleural effusion due to leukemic infiltration of the pleura (1). Long term management of resulting chronic plural effusion can be complicated when there is evidence of trapped lung. Subsequent infection may lead to development of chronic empyema which can be difficult to manage in chronically ill patients (2). CASE PRESENTATION A 65-year-old male with history of chronic myeloid leukemia status post stem cell transplant was admitted with dyspnea and cough. Computed tomography (CT) chest imaging revealed increased volume loss on the left with new air fluid level in a chronic left pleural effusion. (Image 1) Patient's history was significant for chronic left pleural effusion, which was first identified in 2015 and found to be a malignant effusion with evidence of leukemia involvement. Repeat imaging in 2018 (Image 2) revealed continued chronic pleural effusion. Patient was admitted in August 2021 with COVID-19 pneumonia and CT Chest showed chronic loculated left sided pleural effusion. Patient elected to continue to monitor the chronic effusion, which was completed as outpatient every 4 to 6 weeks (Image 3). He remained clinically stable until the presentation to a hospital in January 2022. The chronic empyema was initially managed with tube thoracostomy, intrapleural fibrinolytics and antibiotics. Cultures were significant for Moraxella catarrhalis and Streptococcus pneumoniae. He was determined to be a poor surgical candidate for decortication and treatment with empyema tube was initiated. The empyema tube was incrementally withdrawn as an outpatient and subsequently removed with good clinical recovery. DISCUSSION: Chronic empyema is characterized by thickened parietal and visceral pleura which limits the ability of the lung to re-expand. Surgical management with decortication is the definitive management, however, in poor surgical candidates, management becomes more complicated. Open pleural drainage with an open pleural window can be considered. An alternative option converts tube thoracostomy to open pleural drainage, as was utilized in this patient (2). While comparison of surgical vs non-surgical management of empyema suggests similar mortality (3), non-surgical management of chronic empyema needs more investigation to determine the optimal treatment modality. CONCLUSIONS: Empyema remains a difficult condition to manage. Treatment modalities of chronic empyema are limited in those patients who remain poor surgical candidates.
