Intraorbital, Infratemporal And Intracranial Extensions As The First Presentation Of Follicular Thyroid Carcinoma.

Abstract

Metastatic skull deposits from follicular thyroid carcinoma are rare, and let alone this being the primary presenting symptom with no history of thyroid cancer is exceptionally rarer. A 40-yearold female patient presented with a mass in the temporal and occipital region of the skull. Fine needle aspiration cytology confirmed multiple fragments of a neoplasm composed of variably sized follicles lined by tumour cells having pleomorphic hyperchromatic nuclei. Further workup revealed Follicular thyroid carcinoma and subsequently, total thyroidectomy was done. Skull resection was not possible due to the extensive nature of disease and patient was advised radioactive iodine ablation therapy but couldn't survive past 4 months.
