SAT-472 An Atypical Presentation of Severe Hypothyroidism, a Case of Large Posterior Pericardial Effusion Without Hemodynamic Compromise

BACKGROUND We are reporting a case of a Hispanic female who presented with a pericardial effusion as a complication of hypothyroidism, untreated due to lack of medical care, which demonstrates health disparities in chronic diseases. CLINICAL CASE The patient is a 48 year-old Hispanic female with PMHx of hypothyroidism, non-compliant with medical therapy, who presented to the ED with fatigue and dyspnea. Despite progressively worsening symptoms for the past 4 months, she had refused to be seen by a physician because she was uninsured. Her physical exam was notable for generalized pallor and bradycardia, with otherwise normal cardiopulmonary exam. Her initial laboratory data showed hemoglobin of 5.5 g/dl. CXR demonstrated an enlarged cardiac silhouette, which on CT was found to represent a large pericardial effusion. On admission her laboratory data demonstrated low ferritin, TSH of 94 mIU/L and T4 of 1.4 mcg/dl. m. Cortisol was 9 mcg/dl at 11 am. Repeat hemoglobin post-transfusion was 9 g/dl The patient was started on IV levothyroxine and hydrocortisone. Echocardiogram showed a large posterior wall pericardial effusion without evidence of RV strain. Pericardiocentesis was attempted but was unsuccessful because of difficult access to the fluid location. She was discharged on levothyroxine 88mcg QD and recommended to follow up with endocrinology and cardiology as an outpatient. It is well known that the United States spends a disproportionate amount of money in healthcare in comparison to developing countries (1). Underinvestment in social services and high prices set by pharmaceutical companies are likely contributing factors (1). Unfortunately, the resulting outcomes do not necessarily reflect the spending. Minorities are well known to have a higher morbidity and mortality as well as to present more frequently with dramatic manifestations of chronic diseases. This can often be attributed to a lack of access to medical care and poor follow up. Our patient was diagnosed with pericardial effusion as a complication of untreated hypothyroidism, a condition that is underdiagnosed despite a high incidence (3-37%). This pericardial effusion was initially concerning due to its large volume. The fact that she was hemodynamically stable reflects its chronicity, but it could have led to a fatal complication if she continued without appropriate therapy for a longer period of time. CONCLUSION A case such as this should make us question what more we can do to improve healthcare outcomes for minorities in the USA. REFERENCES (1). Papanicolas, Irene, Liana R. Woskie, and Ashish K.
