A 73-year-old man was transferred to our emergency room with a sudden onset of severe back pain, being under mechanical ventilation because of an intractable pain. His heart rate was regular and blood pressure was 166/96mmHg. A chest computed tomographic scan revealed a massive pericardial effusion associated with type B aortic dissection. His family told us that he had a history of hypothyroidism, and that he had stopped taking medicine several years prior by his judgment. Blood test revealed that thyroid stimulating hormone, free triiodothyronine, and free thyroxine level were 200.93μU/ml, 0.88pg/ml, and below 0.1ng/dl, respectively. We strongly suspected that hypothyroidism caused the chronic pericardial effusion without apparent hemodynamic relevance. To get a definite diagnosis of the effusion, we drained the effusion through the left antero-lateral thoracotomy, considering a subsequent pericardial fenestration to the left pleural cavity. Then, we confirmed that the pericardial effusion was caused by chronic hypothyroidism because of a yellowish and transparent fluid. Treatment for hypothyroidism was initiated postoperatively. The patient was doing well, without pericardial effusion and aortic enlargement, under a euthyroid condition 10 months after the surgery. In conclusion, getting his past history help we choose an adequate treatment in a type B dissection case associated with a massive pericardial effusion.
