Clinical Case: A 48-year-old female with history of 1 year of lumbar pain, a computer tomography was performed where mediastinal tumor and bilateral pleural effusion was diagnosed. A thoracentesis was performed diagnosing bilateral chylothorax. Medical treatment was started without improvement, a left thoracotomy and right thoracoscopy with chemical pleurodesis were performed. Patient improved clinically, dependent of oxygen. Final pathologic exam reported IgG4 negative fibrosant mediastinitis. Discussion: The symptoms of presentation of the disease are not specific and depend on the invasion to adjacent thoracic organs, with the consequent formation of bilateral chylothorax. Conclusions: No curative treatment exists for this disease. It presents with variable mortality, some of 30% at 6 years and it is related with intrathoracic organ affection.
