—In the July Archives (1983;143:1458-1460), Brown et al reported a case of pleural effusions in a 27-year-old woman who had myxedema.

Report of a Case.
—A 22-year-old woman was hospitalized due to the abrupt onset of right upper quadrant abdominal pain. Roentgenograms showed nonvisualization of the gallbladder. Surgery was planned, but it was cancelled when a chest roentgenogram showed cardiomegaly and bilateral pleural effusions. Sinus bradycardia and ST-T abnormalities were present on the ECG. A triiodothyronine (T3) uptake was 34% (normal, 35% to 45%), the serum thyroxine (T4) level was 2.5 μg/dL (normal, 4.5 to 13.0 μg/dL), and the thyroid-stimulating hormone level was 92 μU/mL (normal, 0 to 8 μU/mL).Findings from
