Gallium scans and serum angiotensin converting enzyme levels in talc granulomatosis and lymphocytic interstitial pneumonitis.
We have described two patients who had positive gallium lung scans with simultaneous elevation in serum angiotensin converting enzyme (SACE) levels. One patient had talc granulomatosis secondary to the intravenous injection of pentazocine, while the other patient had lymphocytic interstitial pneumonitis. We believe these are the first cases in which a positive gallium scan and elevated SACE levels were associated with these entities.
