Uniportal video-assisted thoracoscopic fissureless right upper lobe anterior segmentectomy for inflammatory myofibroblastic tumor

Abstract

Abstract Inflammatory myofibroblastic tumor is an exceptionally rare neoplasm with intermediate malignant potential. Surgery is the accepted mode of treatment, aiming for complete resection with clear margins. Herein, we describe a 39-year-old woman who underwent right upper lobe anterior segmentectomy of an asymptomatic pulmonary nodule by way of uniportal video-assisted thoracoscopy. A provisional tissue diagnosis of malignancy was later revised to inflammatory myofibroblastic tumor. Absence of a minor fissure between right upper and middle lobes called for an alternate approach to resection. We injected indocyanine green to clearly delineate the intersegmental plane. After an uneventful recovery, patient discharge was on postoperative Day 3. Annual chest tomography scans are planned to monitor for potential local recurrence. This particular case underscores the challenges in diagnosing and managing such tumors, showing the importance of accurate pathologic assessments and tailored surgical strategies.
