We report a case of extra\u2010adrenal paraganglioma in the hilum identified after treatment for multiple intrathoracic lymph node metastases from testicular cancer. A 32\u2010year\u2010old man presented to the hospital with a cough. Computed tomography revealed multiple lung tumors and intrathoracic lymph node swelling. The patient was diagnosed with left\u2010sided testicular cancer with multiple intrathoracic metastases. A left orchiectomy was performed, followed by chemotherapy. A lung biopsy confirmed the absence of residual cancer. Three months after the lung biopsy, <jats:sup>18<\/jats:sup>F\u2010fluorodeoxyglucose positron emission tomography\/computed tomography revealed fluorodeoxyglucose uptake in the right hilum.
