Two Cases of Benign Solitary Schwannoma with Pleural Effusion

Schwannoma represents approximately 40% of neurogenic tumors arising in the mediastinum, and develops along the sympathetic or parasympathetic chain, intercostals nerve, and spinal ganglia. It is usually asymptomatic, and is confronted accidentally but can produce chest pain, cough and dyspnea. However, dyspnea with pleural effusion is rare in patients with benign schwannoma. We encountered two cases of benign schwannoma with pleural effusion. Both cases had similar initial symptoms and the characteristics of a mass but the characteristics of pleural effusion analysis were different. The benign schwannoma was confirmed in two cases using VATS (video-assisted tharawswpic surgery).
