Thyroid swellings with altered thyroid bio chemistry (T3, T4, TSH) are easier to manage with out biopsy. Tumours with normal thyroid function were routinely subjected to fine needle aspiration cytology.
Despite the theoretical advocation FNAC is found in our series to be basically unreliable when used in isolation. Though expensive it is worth doing a MRI or CT or Ultrasound scan for neck to detect Lymph nodes. Incase of multiple nodes despite a benign FNAC we should consider Malignancy. Antithyroid antibodies are vital to rule out Thyroiditis. Many times Hashimotos masquerading as tumour has been operated with high incidence of recurrent laryngeal nerve palsy. This is due to fibrosis of thyroid pulling the R.L. Nerve out of the tracheo oesophageal groove into the gland. Most of the cases of bilateral RLN palsy refered to MCV Hospital for laser cordotomy were operated for suspected thyroid tumours later on proven as Hashimotos thyroiditis. |
