RESUMO
A 62 year-old man presented with massive pericardial effusion and a thyroid nodule. One thousand ml of serosanguinous pericardial effusion was tapped and the cytology consistent with metastatic papillary carcinoma. Total thyroidectomy was done. The pathological report of the thyroid gland was follicular carcinoma, poorly differentiated with capsular and vascular invasion. The patient received a treatment of 150 mci I-131 without complications. The total body scan after I-131 treatment showed only residual thyroid tissue. There was no demonstrable abnormal uptake in other parts of the body. No significant reaccumulation of pericardial fluid occurred. The diagnosis was follicular carcinoma of the thyroid with pericardial metastasis. The patient was discharged from the hospital with an improved clinical status.

The presence or absence of thyroid glandular tissue demonstrated by thyroid scintigraphy is important for genetic and prognostic counseling and for acceleration of diagnosis in other affected siblings. Technetium-99m-pertechnetate thyroid scintigraphy was performed on 27 children with cretinism at the Division of Nuclear Medicine, Faculty of Medicine Siriraj Hospital during the 5-year period from June 1991. Based on scintigraphic findings, three main groups of thyroid localization were seen. Thirteen (48.1%) were athyrotic while 3 (11.1%) had an ectopic thyroid and 11 (40.8%) had gland in normal position. Perchlorate discharge test was performed in 8 children of the last group and the results were positive indicating an organification defect. Thyroid scintigraphy and perchlorate discharge test provided the useful information for diagnosis, follow-up, and prognosis in children with cretinism.
