title: Recurrent hematuria in a patient with a history of anaphylactic reaction to radiographic contrast.
abstract: Hematuria is a relatively common problem, but its evaluation can be complicated. One must pay attention to the patient's symptoms and extrarenal manifestations of disease to identify the etiology efficiently. We present the case of a patient who narrated a fascinating past medical history and a dramatic presentation of hematuria that had been exhaustively evaluated at another hospital. During a prolonged and involved stay at our institution, the etiology of the hematuria remained enigmatic after extensive radiologic and invasive investigations that led to internally inconsistent findings, until an unusual diagnosis was entertained.
