[Treatment of Secondary Spontaneous Pneumothorax due to Tumor Rupture:Report of a Case].

A 64-year-old man undergoing chemoradiotherapy for lung adenocarcinoma with systemic metastases was admitted for a malignant pleural effusion in the left thoracic cavity that necessitated a drainage and pleurodesis with talc. After pleurodesis, an air leak occurred, which led to surgical intervention. Preoperative computed tomography (CT) scans and intraoperative findings revealed multiple nodules in the lungs and a fistula due to ruptured tumor. Extensive adhesions by pleurodesis made typical resection difficult. As a result, the patient was treated with absorbable tissue repair material and adhesive. No persistent air leaks were observed postoperatively. The patient underwent a subsequent pleurodesis with picibanil. This case illustrates the challenges, which emphasize the need for alternative air leak management strategies when resection is not feasible.
