RESUMO
A thyroidectomy is a safe and low-risk procedure done for a wide variety of thyroid disorders. Complications of a thyroidectomy are commonly due to damage of structures adjacent to the thyroid gland. In this case report, we present the case of a 39-year-old patient with a cervical pneumatocele a month after thyroidectomy for thyroid papillary carcinoma. The symptoms included neck swelling when speaking that resolved with rest. A follow-up neck CT scan found a collection of air anterior to the trachea most compatible with cervical pneumatocele. Exploratory surgery ensued and a pneumatocele arising from a tracheal subcutaneous fistula was cauterized. On follow-up laryngoscopy a month later, no further complications were found, and the patient reported resolution of symptoms. Tracheal injury following thyroidectomy is a rare complication and CT imaging can be helpful in diagnosing these complications and expediting management.
