An Unusal Presentation of Follicular Carcinoma of Thyroid

ABSTRACT

Although the incidence of thyroid carcinoma hasincreased in recent years, metastatic spread to the skullis rare. Here we report a case of an occult follicularthyroid carcinoma. A 65 year old female patientpresented with a large swelling of 20 × 20 cm over thefrontal and parietal regions for 2 years. MagneticResoning Imaging (MRI) showed well definedlobulated mass in bilateral frontal and parietal regionswith cystic and solid components. Incisional biopsy ofthe mass was done and was reported as metastaticfollicular carcinoma with transformation to anaplasticvariant. In view of this report the patient underwenttotal thyroidectomy, the biopsy report confirmed thediagnosis of follicular carcinoma. Surgery is the maintreatment for resectable metastatic differentiated131 thyroid carcinoma, followed by I ablation andthyroid stimulating hormone suppression withlevothyroxine
