We present the case of a woman with metastatic adenoid cystic carcinoma who received stereotactic ablative radiotherapy (SABR) with a total dose of 50 Gy in 4 fractions to two lung metastases and developed symptomatic left phrenic nerve injury 2 years after radiation. The maximum dose to the approximate location of the phrenic nerve was 57.7 Gy which corresponds to a biologically effective dose for late effects (using a/ß ratio?=?3) of 335.14 Gy. Here, we discuss the case, planning considerations by radiation oncologists and medical physicists, and the multidisciplinary medical management of this patient.
