Isolated Skull Metastasis of Follicular Carcinoma Thyroid in an Elderly Female: A Rare Case

Abstract

Isolated skull metastasis from a well differentiated follicular thyroid carcinoma, as the presenting feature is a rare manifestation. We report a case of a 79-year-old female who presented to us with only a painful, gradually increasing scalp swelling with associated pain and blurring of vision over the past few days. Neuroimaging findings strongly favoured a diagnosis of meningioma. A bifrontal craniotomy was performed and the tumour was excised. Histopathological examination of the same showed, it to be a case of metastatic thyroid carcinoma. We present this case not only because of the diagnostic challenge it posed, but also because the patient in our case is one of the oldest case of skull metastasis from follicular thyroid carcinoma till date.
