Tumours of the mediastinum are rare and require skilled radiologists and surgeons for proper diagnosis, staging and treatment. The centre has facilities for image-guided biopsy, mediastinoscopy, transbronchial biopsy and thoracoscopy for diagnosis and surgical management. Thoracoscopicthymectomy is a good approach for the treatment of myasthenia gravis when surgery is indicated. It does away with sternotomy and reduces hospital stay.
