Idiopathic Fibrosing Mediastinitis with Non-Compressive Symptoms: A Case Report on Its Surgical Treatment

Herein, we report a case of surgically treated idiopathic fibrosing mediastinitis. A 32-year-old man has an unknown fever. Several medications, including prednisolone, failed to improve his symptoms. (18)F-fluorodeoxyglucose positron emission tomography/computed tomography revealed the abnormal accumulation of the mediastinal and left neck lymph nodes. A definite diagnosis could not be obtained despite an incisional biopsy of the left neck lymph node. We performed robot-assisted thoracic surgery resection of the mediastinal lesion. The pathological diagnosis was idiopathic fibrosing mediastinitis. After surgical treatment, significant clinical improvements were observed. Few reports showed the effect of surgery on idiopathic fibrosing mediastinitis patients with non-compressive symptoms.
