RESUMEN
Follicular thyroid carcinoma is a well-differentiated thyroid neoplasm that is classified into widely invasive or minimally invasive carcinoma. Vascular invasion is often characteristic of follicular thyroid carcinoma. There is an estimated 6-20% incidence of distance metastasis with the bone being the most common followed by the lungs and then the lymph nodes. Metastatic spread to the skull base is rare. This case report will cover a patient who presented with follicular thyroid carcinoma and cranial neuropathy and was found to have metastasis to the skull base.
RESUMEN
Multiple endocrine neoplasia type 2 is an autosomal dominant neoplastic syndrome with subtypes multiple endocrine neoplasia type 2A, multiple endocrine neoplasia type 2B, and familial medullary thyroid carcinoma. Medullary thyroid carcinoma universally coincides with multiple endocrine neoplasia type 2. Multiple endocrine neoplasia type 2A is a rare disease and the affected patients are generally asymptomatic. The morbidity and mortality are mainly due to medullary thyroid carcinoma and often proper clinical workup is warranted for expedited surgical intervention. Total thyroidectomy along with neck dissection may be required for disease control. This report will cover a patient who presented with medullary thyroid carcinoma and was worked up to have multiple endocrine neoplasia type 2A. She underwent total thyroidectomy with central neck dissection.
