摘要
Introduction: A particularly challenging case of concurrent acromegaly and follicular thyroid carcinoma in a patient of the Clinic of Endocrinology, UJCM in Krakow is discussed.
Case description: A 59-year-old male with post total thyroidectomy performed in 2005 and histopathologically confirmed metastases of the follicular thyroid carcinoma to the lungs was admitted to the Clinic in April 2006 for complementary I-131 treatment. Acromegaly was treated in 1996 by trans-sphenoidal surgery. In December 2005 a relapse of pituitary adenoma was shown by MRI, which correlated with increased levels of hGH and IGF-1. Biochemical control of acromegaly was achieved with Sandostatin LAR. Pre-therapeutic whole-body scintigraphy (WBS) revealed numerous conjoined hot spots of I-131 accumulation in both lungs and in thyroid remnants. In May and November 2006 the patient received I-131 treatment. Post-therapeutic WBS in November 2006 revealed complete ablation of the thyroid remnants. Laboratory tests confirmed lowering of thyroglobulin concentration. In the years 2007, 2008, and 2009 the patient was qualified for therapy with I-131 aided by rhTSH, achieving further reduction of Tg levels. Post-therapeutic WBS performed in 2009 revealed weak bilateral tracer uptake in the lung parenchyma. In 2010, chest CT revealed fibrosis in left lung segments, no infiltrative changes, and no lymph node enlargement. Patient follow-up continues at our Department.
Conclusions: Disseminated thyroid cancer in a patient with pituitary insufficiency may be successfully treated by rhTSH-supported I-131 treatment. (Pol J Endocrinol 2010; 61 (5): 497-501)
