Bladder schwannomas are exceedingly rare, benign or malignant, nerve sheath tumors that are most often discovered in patients with a known diagnosis of Neurofibromatosis type 1 (NF1). A few sporadic case reports of bladder schwannoma have been published in urologic, obstetric/gynecologic, and pathologic journals. However, this is the first case report in the radiologic literature where computed tomography imaging and radiology-specific descriptions are discussed. Furthermore, the patient presented in this case is only the fifth published patient without NF1 to be diagnosed with a bladder schwannoma, to the best of our knowledge.
