Clinical study of prevalence of malignancy in nodular thyroid swelling

Background: Large proportion of thyroid cancers arose from a pre-existing adenoma or from multinodular goiters. Surgical practice of removing thyroid nodule or multiple nodules of thyroid gland has been challenged for surgeons to prevent cancer. Aim of this study is to find out the prevalence of malignancy in solitary thyroid nodule and multi-nodular goitre in relation to age and sex. The aim of the study was to determine the incidence of malignancy in patients who underwent thyroidectomies.Methods: Study of 100 cases of nodular thyroid swelling has been done during the period from November 2017 to November 2019 on inpatients admitted to GEMS Hospital, Srikakulam, and Andhra Pradesh, India. Detail clinical examination, relevant investigations, surgical management and histopathological reports were collected and analyzed using software package for statistical analysis (SPSS 20).Results: Out of 100 patients with thyroid swellings, thyroid malignancies constitute 4%. The occurrence of thyroid cancer was maximum in the 4th decade of life. Female patients outnumbered males with a ratio of 4:0. Relative frequency of malignancy in solitary thyroid nodule was 4.76% and in multi-nodular goitre was 3.03%. Most common histopathological type was papillary carcinoma thyroid (50%); followed by follicular carcinoma thyroid (25%) and medullary carcinoma (25%).Conclusions: The prevalence of thyroid malignancy in the present study is at an earlier age group due to early diagnosis and treatment. The prevalence of thyroid cancer is higher in female when compared to those reported in the literature. The proportion of medullary cancer is more in present study.

SKULL METASTASES OF FOLLICULAR CARCINOMA THYROID: A RARE CASE REPORT

The thyroid gland, usually located below and anterior to the larynx, consists of two bulky lateral lobes connected by a relatively thin isthmus. The thyroid is divided by thin brous septae into lobules composed of about 20 to 40 evenly dispersed follicles, lined by a cuboidal to low columnar [1] epithelium, and lled with PAS-positive thyroglobulin. The thyroid secretes hormones that control the heart rate, blood pressure, body temperature and basal metabolic rate

Cervical extradural metastasis from follicular carcinoma thyroid after 14 years post-thyroidectomy with Elsberg phenomenon

Background. Follicular carcinoma thyroid usually metastasises to bone. Common sites of bone metastasis include skull and spine. Spinal metastasis are more common in the cervical region followed by dorsolumbar spine. Cervical extradural lesions present with progressive quadriparesis, sensory loss, dysautonomia, and respiratory distress. Typical Elsberg phenomenon in a cervical extradural lesion is rare. Elsberg phenomenon involves the involvement of ipsilateral upper limb, ipsilateral lower limb followed by contralateral lower limb and contralateral upper limb. Case presentation. We are reporting a case of 47-year-old lady presented with progressive quadriparesis of 1-month duration. Her weakness started in left upper limb followed by left lower limb, right lower limb and right upper limb weakness. She also had sensory loss below the level of C7. She had undergone near-total thyroidectomy for solitary thyroid nodule 14 years back and was on thyroid supplementation since then. Histopathology at that time was reported as follicular adenoma with Hashimoto thyroiditis. Her right upper limb power was grade 4- Left upper limb grade 1 right lower limb Grade 3, left lower limb grade 2 with hypertonia of both upper and lower limbs. She was evaluated with MRI Spine which showed a dumb bell-shaped extramedullary lesion involving the C5-C6 vertebra with significant cord compression and encasement of the left vertebral artery. USG neck showed left supraclavicular lymph node enlargement and small residual thyroid tissue in the left side of the thyroid. USG guided FNAC from the thyroid tissue and neck nodes were inconclusive. The patient underwent C4 and C5 laminectomy and subtotal excision from the cervical lesion. Histopathology was reported as metastasis from follicular carcinoma thyroid. Postoperatively patient limb power improved to grade 3 left upper and lower limbs and was discharged and later referred for radioiodine ablation Conclusion. Cervical extradural metastasis from follicular carcinoma thyroid can present with Elsberg syndrome even without any neck swelling even after decades of post thyroidectomy status for a benign aetiology. Laminectomy and decompression may lead to clinical improvement.

Follicular carcinoma of thyroid presenting as brain metastasis

Metastatic brain tumors are a major cause of mortality in cancer patients. The primary tumor is most commonly seen in the lung, breast, colon and kidney and very rarely in the thyroid. We discuss a case of a 55year old lady with presenting complaints of seizures. There is a past history of carcinoma thyroid for which she had underwent total thyroidectomy. Craniotomy was done and histopathological examination revealed metastatic deposits from follicular carcinoma thyroid.
