We report on a case of a 55-year-old female, patient, who presented with clinical signs suggestive of myasthenia gravis over a period of approximately 3 months. The therapeutic option using neostigmine gave an improvement of the dysphagia and palpebral ptosis. A chest radiograph image demonstrated a mass occupying the medium mediastinum with projection to the right. Computed tomography of the thorax revealed the presence of a mass in the medium mediastinum, and thus surgery was inicated. During the operation the was was observed in the medium mediastinum suggesting thymoma. What caught our attention was the unusual location of the tumor as normally thymomas are found in the upper and anterior mediastinum.
