Objective:
Benign nerve sheath tumors are the most common neurogenic tumors of the mediastinum in adults. Intrathoracic schwannomas are generally placed in posterior mediastinum and constitute approximately 75% of all tumors in this region. Since they are usually asymptomatic and seen as well circumscribed solitary mass in the thoracic images, a variety of pathologies can be attributed as prediagnosis. In this study, we aimed to investigate retrospectively 10 cases of schwannoma who were diagnosed between the years 2006-2014.
Material and Methods:
The patients who were diagnosed as schwannoma in Süreyyapaşa Chest Diseases and Chest Surgery Training and Research Hospital between 2006-2014 were analyzed retrospectively.
Results:
Six of the ten cases of schwannoma were female (60%) and four were man (40%). The mean age was found 46 years. Most common symptom is cough and it was followed by chest pain. When Thoracic CT findings were examined, in six cases (60%) lesions were located in the upper mediastinum, and in nine cases (90%) the lesion was located in the paravertebral area. Endobronchial lesion was not seen in fiberoptic bronchoscopic examination of all patients. All patients were diagnosed by surgery.
Conclusion:
The diagnosis of Schwannoma cases, which are most commonly encountered by the involvement of the upper mediastinum, and are often benign characteristically require invasive surgical intervention.
