An Unusual Case of Thyroid Papillary Carcinoma with Solitary Cerebral Metastasis Presenting with Neurological Symptoms

Papillary carcinoma of the thyroid is well known for metastasis to regional lymph nodes resulting in early detection and overall favorable prognosis. Solitary metastasis of papillary carcinoma of the thyroid in the cerebrum is extremely rare with only a few cases reported in the literature. Here, we report an unusual case of a 40-year-old female patient who presented with neurological symptoms and a radiological diagnosis of meningioma was made. Subsequent histopathology from the resected brain tumor revealed a solitary cerebral metastasis from papillary carcinoma of the thyroid. There was no involvement of regional lymph nodes and the radiological findings were indicative of a primary brain tumor.
