Abstract
Authors present a rare case of bifocal schwannoma of thoracic wall showing metabolic activity on FDG PET images. A 43-year-old male with palpable mass on lateral chest wall was referred for F-18 FDG PET/CT imaging for differential diagnosis. His medical history and basic laboratory results were unremarkable. PET/CT images revealed a mild FDG uptake in the solid soft tissue mass in the left lateral chest wall that was growing outside of the thorax. It was located in 7th intercostal space and adjacent ribs were intact. Incidentally, second mass lesion was detected in the right posterior seventh intercostal space protruding to the pleural space and showing higher FDG uptake on PET/CT images. The lesions were surgically removed at the same session for definite diagnosis and treatment. Histopathologic evaluation of both lesions revealed benign schwannoma.
Highlights
Benign tumors of thoracic wall are uncommon lesions and may originate from bone, cartilage, blood vessels, fat or nerves
Chest wall schwannoma is rare and usually found as asymptomatic solitary lesions growing towards the pleural space in the posterior mediastinum
They arise from spinal nerve roots and intercostal nerves and typically occur in patients between the second to fifth decades
