Diagnosing the Treatment

Teaching Points

• Complications of intravesical BCG treatment include manifestations of granulomatous diseases, such as hypercalcemia.
• When generating a differential diagnosis, medical providers should not only consider the possibility of a new disease process or the progression of a known comorbidity but also the potential of an adverse effect related to prior treatments.
• Medical providers should be wary of accepting previously made diagnoses, particularly when key pieces of objective data are lacking.
