The patient was wheelchairbound because of a history of transverse myelitis. She had urinary incontinence and was dependent on chronic urinary catheterization. The patient had no symptoms beyond discolored urine. There was no dysuria or blood around the catheter. She had no history of trauma to the catheter. On examination, she was afebrile and well appearing, but the urine in her catheter bag looked purple (Figure 1). She did not know how long her urine had been discolored. Urinalysis showed leukocytes and microscopic hematuria. The urine was sent for culture.
