Diagnosis With Brief Discussion
- Diagnosis
- Miliary metastasis from Thyroid cancer
- Radiologic Findings
- Papillary Carcinoma of thyroid is occured in 60% (20% follicular, 15% anaplastic, 1-5% medullary carcinoma) of all thyroid carcinomas, metastasize to regional lymph nodes in 40%, hematogenous to lung in 4%(early spread to lung and bone in follicular carcinoma). In papillary carcinoma, tumor usually concentrates radioiodine, but in follicular carcinoma, tumor usually concentrates pertechnetate.
Of 731 patients with papillary thyroid cancer, 91 had metastases outside regional lymph nodes. The most common site was intrathoracic, occurring in 73 of the 91 patients. Miliary, micronodular pulmonary metastases, with iodine 131 (I-131) uptake and "curable" by I-131 treatment were encountered in 7 patients. (Hoie J, et. al. Cancer;1988(61)1-6 )
