Abnormal captopril scintigraphy in Bartter syndrome.
A 37-year-old patient with severe hypokalemia (approximately 1.7 mEq/L) and muscular weakness had a very high serum renin level. No renin-producing tumor was found and she was diagnosed with Bartter Syndrome The parathyroid hormone level was high due to concomitant renal calcium loss. Tc-99m-DTPA captopril scintigraphy was performed to confirm the diagnosis.
