Perineurioma (storiform perineurial fibroma) of the kidney in a child.
Perineurioma is an extremely rare benign tumor of the peripheral nervous system composed exclusively of perineurial cells. Imaging findings of this tumor are non-specific and the diagnosis is based on histologic studies. We report a case of perineurioma of the kidney in a 7-year-old girl discovered incidentally during the evaluation of a urinary tract infection. This is the first case of renal perineurioma reported in a child. We present the ultrasound and computed tomography findings of this histologically confirmed neoplasm.
