A case of bi-focal mediastinal ependymoma

Ependymomas are tumors located in the central nervous system, mostly in the brain and spinal cord. This tumor is rarely seen as a primary mediastinal location. The aim of this study is to discuss this rare pathology in the clinical course of an unusual case. A 47-year-old female patient was referred to our clinic with the complaint of back and shoulder pain, via VATS posterior mediastinum located paravertebral mass excision was performed. The pathology reported as ependymoma. Two years later, CT scans of the routine control showed the well-defined mass in anterior mediastinum. The SUVmax of the lesion was measured as 9.3 at PET-CT. The lesion in the anterior mediastinum was excised by partial sternotomy. The pathology result was the same as the prior operation: Ependymoma. As our case, in these kinds of tumors meticulous follow-up of the patients is important for the detection and treatment of recurrent localization and distant metastases.
