Flashcard 151: Cardiomegaly and asymptomatic pericardial _____ are seen in congenital hypothyroidism

Answer: effusion

Flashcard 152: Thyroid acropachy is seen with _____thyroidism

Answer: Both Hyperthyroidism and Hypothyroidism (specifically in Graves' disease)

Extra: Thyroid acropachy is a rare extrathyroidal manifestation of **Graves' disease** (<1%). It is characterized by subperiosteal bone formation, clubbing, and soft tissue swelling. While Graves' disease is the most common cause of hyperthyroidism, acropachy is an autoimmune manifestation (similar to ophthalmopathy and dermopathy) rather than a metabolic one. Therefore, it can be seen regardless of the patient's current metabolic state (hyperthyroid, euthyroid, or hypothyroid post-treatment).
