A 46yo male presented with anterior neck swelling and erythema that rapidly progressed over the past day. He had a history of thyroid nodules. He also reported mild vocal changes and dysphagia.

Cystic nodules within the thyroid are often benign adenomatous nodules, with degeneration or hemorrhage. Other types include benign follicular adenomas or malignancy, such as papillary thyroid carcinomas, which often have accompanying cystic degeneration.

His symptoms markedly improved after aspiration- which is often not the case if the nodules are more complex.
