Aseptic Thyroid Abscess

Abstract

An elderly diabetic female presented with fever, swelling, and pain over the anterior aspect of her neck for one week. Clinical examination revealed a firm 4x3 cm swelling with warmth and tenderness. CT neck showed a colloid cyst with rupture and fluid collection within the thyroid gland, associated with inflammation. USG-guided FNAC indicated necrotic material. A hemithyroidectomy was performed, revealing pus within the gland. Frozen section confirmed non-malignancy. Postoperative recovery was uneventful, and pus culture showed no bacterial growth, consistent with an aseptic thyroid abscess. The patient had an uneventful follow-up.
