title: Evaluation of rare choroid plexus metastasis from papillary thyroid carcinoma with multimodality imaging.
abstract: Papillary thyroid carcinoma (PTC) is the most common malignancy of thyroid gland. Though it metastasizes primarily through lymphatics, hematogenous spread is not infrequent. We report the case of a 62-year-old male patient with intraventricular choroid plexus metastasis from PTC, incidentally detected on post-high-dose radioiodine therapy whole-body I scan, which is an extremely rare presentation. Only 3 cases of choroid plexus metastasis from thyroid carcinoma have been reported. Further multimodality radiological investigations confirmed diagnosis and helped in assessing treatment response. The patient received gamma-knife stereotactic radiosurgery, and follow-up radiological imaging suggested improvement of intracranial metastasis.
