Needle in a Haystack: Post Thymectomy New Onset Myasthenia Gravis

Summary Myasthenia gravis can develop after resection of thymic tumors. Post-thymectomy myasthenia gravis can be heralded by elevated preoperative anti-acetylcholine-receptor antibodies. Thymic tissue in isolated mediastinal areas can be the culprit lesion and identified by PET SCAN. Re-resection in selected patients can lead to remission of this rare disease.
