A rare case of large pericardial effusion in a child with severe primary hypothyroidism

Thyroid disorders are a common clinical entity and hypothyroidism is the most common thyroid disorder encountered in the Indian population. Its diagnosis is simple but often remains undiagnosed or misdiagnosed because of the sub-clinical course of disease. It was a familiar scenario in the past when diagnosis of hypothyroidism was confirmed after admission of patient due to complications secondary to hypothyroidism such as myxedema coma, infertility, impaired fertility, goiter, easy miscarriage, birth defects, mental retardation, dyslipidemia, psychological problems, cardiomyopathy, heart failure, depression. Usually, such case reports were reported in adult patients. We are reporting a case of large pericardial effusion in a child with severe primary hypothyroidism.
