Hi. Thanks for your query. You have two altogether different problems. - The swelling in the left palatoglossal arch may be a different problem like a mass or a cyst. This can be diagnosed by: CT scan and FNAC and may need an active treatment or formal surgery. -Another problem is the thyroid. The reports says: 1. Mild thyromegaly without cyst or nodule. Acute or subacute is difficult to exclude by ultrasound and 2. Small reactive appearing lymph node in the mid anterior left neck . You need further investigation of FNAC of the thyroid as this type of swelling may be due to thyroiditis and the resultant lymph node. Reactive means not a cancer. It is also needed to get Thyroid function tests, anti-thyroid antibody tire and another blood tests to decide the further treatment which will be necessarily a medical management depending upon the reports.
