title: Symptomatic ascites in a patient with hypothyroidism of short duration.
abstract: Symptomatic ascites as a presenting symptom of hypothyroidism is quite rare. In most of the case reports, patients with ascites requiring therapeutic abdominal paracentesis have long-standing hypothyroidism. We present a case of symptomatic ascites in a subject with hypothyroidism following radioiodine therapy for Graves disease. A 70-year-old African-American man presented with increasing weakness, shortness of breath, weight gain, constipation, and abdominal distention. Past history was significant for coronary artery disease, diabetes, hypertension and history of radioiodine therapy for Graves disease 9 months prior to the presentation. He was taking levothyroxine at 50 microg per day for 3 months prior to the presentation. Physical examination findings were significant for puffiness around the eyes, decreased breath sounds at the lung bases, and distended abdomen with free fluid, hung-up reflexes, and cold extremities. The thyroid-stimulating hormone level at the time was 64 with a free T4 less than 0.4 ng/dL. Analysis of the ascitic fluid revealed an exudative effusion with a serum to ascitic fluid albumin gradient of 1.2. The patient required therapeutic abdominal paracentesis twice, with 4 L each time, to relieve the symptoms. Work-up to rule out other causes did not reveal any other relevant abnormality. After initiation of thyroid hormone replacement, the patient responded very well and the ascites resolved within 2 months. We conclude that ascites associated with hypothyroidism is rare but must be recognized early, since thyroid replacement is the definitive therapy.
