We present a female in her sixties with mixed connective tissue disease who underwent 99mTc-human serum albumin diethylenetriaminepentaacetic acid ( 99mTc-HSA-DTPA) scintigraphy to clarify the cause of generalized edema. Scintigraphy findings directed the diagnosis to protein-losing gastroenteropathy. Various disorders are known to be associated with proteinlosing gastroenteropathy; however, mixed connective tissue disease is a rare cause. 99mTc-HSA-DTPA scintigraphy is helpful in the diagnosis and following the response to therapy of protein-losing gastroenteropathy.
