Extrapulmonary Soft-Tissue Fibrosis Resulting From Hypofractionated Stereotactic Body Radiotherapy for Pulmonary Nodular Lesions

The findings of any new lesion should prompt an assessment for radiation-induced extrapulmonary fibrosis before an immediate diagnosis of recurrence is made. Careful beam-shape modification and dose prescription near the thoracic outlet are required to prevent forearm neuropathy and lymphedema.
