Figure 1. The clinical course of the early stage of the patient’s disease onset. The course of each symptom is shown in the lower column. Loxoprofen and morphine sulfate hydrate were administered to relieve cervical tightness and dyspnea, respectively. EBUS-TBNA on day 29 of onset and CT-guided biopsy on day 37 failed to reach a pathological diagnosis. A surgical biopsy scheduled on day 45 was postponed and was performed on day 84 when symptoms were relieved by steroid administration. CT – computed tomography; EBUS-TBNA – endobronchial ultrasound-guided transbronchial needle aspiration; Dex – dexamethasone; mPSL – methylprednisolone.
