A 70-year-old man with no history of pleural diseases had a dumbbell-shaped chest wall mass extending from the thoracic cavity to the spinal canal at the intervertebral foramen without bone destruction. Computed tomography revealed a positive a 'pleural sandwich sign', where the intercostal artery was enveloped by the mass. A high maximum standard uptake value was noted on fluorodeoxyglucose-positron emission tomography. No lesions were found in areas other than the chest wall. CT-guided biopsy was performed and he was diagnosed with primary chest wall lymphoma. This case report suggests that these radiographic findings may be helpful for diagnosing chest wall lymphomas even in patients without prior pleural disease.
