Metástasis cerebral de carcinoma papilar de tiroides, reporte de un caso

Abstract

Papillary thyroid carcinoma has a natural tendency to metastasize to regional lymph nodes without influencing its prognosis. Distant metastasis is rare, 1%-14% and the most common sites are the lung and bone. Brain metastasis defined as the presence of cancer in another part of the body, in this case thyroid, which spreads to the brain is rare and is associated with aggressive variants of the tumor and occurs in 0.1% - 5% of cases. The case of a 46-year-old male patient with no significan family history and a clinical history of papillary thyroid carcinoma is presented in whom a radical thyroidectomy plus lymph node dissection was performed (04/15/2011), due to pathology report of metastasis, treatment with I131 was also started, he went to the consultation 2 years after treatment due to severe headache plus seizures, he was admitted to Neurosurgery. The diagnosis was made by magnetic resonance imaging and the treatment carried out was a two-stage surgery, first the resection of left occipital metastases and then the resection of bilateral deep parietal metastases, which has shown an increase in the survival of patients in months. Being a case that occurs infrequently, it is necessary to review important aspects of the pathology such as its diagnosis and treatment, providing information on the results obtained in this patient that can be used in later cases.
