Abstract
Tubulocystic carcinoma of the kidney is a rare neoplasm occurring predominantly in males, and has a relatively indolent disease course. Herein, we present a case of histologically proven tubulocystic renal carcinoma in a 22-year-old woman with emphasis on the imaging findings of CT, US, 18-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography ($^18{F}$-FDG PET/CT), and pathological features. Unusually, the woman had single bone metastasis in the left parasymphyseal pubic bone without any other evidence of metastatic disease on $^18{F}$-FDG PET/CT at the time of the diagnosis. A few months later, the bone metastases progressed into multiple cervical vertebrae and the skull base.
