AbstractAbstract PDF
Carcinoma of the parathyroid gland is rare, comprising only 0.1% to 5% of all patients with primary hyperparathyroidism. It presents with severe hypercalcemia, bone disease, palpable neck mass, renal involvement and etc. Since the initial operation offers the best chance for cure, preoperative localization and intraoperative recognition of parathyroid cancer are essential. Recently parathyroid imaging has been described with 99mTc-sestamibi as an alternative to 201Tl. This newer agent has many physical and dosirnetric advantages and represents higher detection sensitivity than 201Tl-99mTc subtraction scan. We experienced a 41-year-old man presenting with recurrent hyperparathyroidism in spite of 2 previous operations. In preoperative localization, there was no abnormal uptake in 201Tl-99mTc subtraction scan but 99mTc-sestamibi scan revealed metastatic foci on right cervical area. He was successfully treated with modified radical neck dissection.

AbstractAbstract PDF
Cushing's syndrome associated with nodular adrenal glands will be divided into four main categories: adrenal adenoma, adrenal carcinoma, primary pigmented nodular adrenal dysplasia (PPNAD) and macronodular adrenal hyperplasia(MAH). The term macronodular adrenal hyperplasia is restricted to the presence of multiple nodules visible to the naked eye, ranging in size from 0.5 to 7.0 cm. We report a case of Cushings syndrome caused by bilateral macronodular adrenal hyperplasia (MAH). A 45-year-old man presented with Cushingoid features, hypertension and diabetes mellitus. Urine free cortisol was 449.9 mmol/day(27-276) and were not suppressed after administration of low-dose and high-dose dexamethasone. Plasma ACTH was very low(1.87 pmol/L(18)) and was not stimulated by administration of ovine CRH. In abdominal CT, both adrenal glands were markedly enlarged and nodular in appearance. Pituitary MRI showed no abnormal finding. Bilateral adrenalectomy was done. Histologic examination revealed multiple nodules and internodular hyperplasia. This case and other reports suggested that because of variable biochemical, radiologic and pathologic findings, macronodular adrenal hyperplasia represents a heterogeneous group of patients with varying degrees of adrenal autonomy.

Background
Whole body scan using 131-iodine is performed to detect local recurrence or metastasis after thyroidectorny in differenciated thyroid cancer patients. The sensitivity of this procedure is related to the dose of radiopharmaceutical administered. It was reported that 131I posttreatment whole body scan demonstrate foci of tracer uptake not previously observed in diagnostic scan in 10~30% of cases. Posttreatment scans were most likely to reveal new foci in young patients(<45) and patients who had previously received radioactive iodine therapy. Method: We observed the frequency of discordant posttreatment scans and analysed the clicnical significance in 33 differenciated thyroid cancer patients who were admitted for radioiodine ablation from June, 1995 to April, 1996. Results: In 7 cases(21.2%), post treatment scan demonstrated cme or more foci of uptake and revealed less sites of uptake than diagnostic scan in 3 cases(9.1%). In one case with elevated thyroglobulin level and negative diagnostic scan, post treatment scan revealed new uptake sites with thyroid bed and cervical 1ymph node. The sites of discordant uptake were cervical lymph nodes in 4 cases and rnediastinal lymph node in one case, lung in one case, thyroid bed and cervical lymph nodes in one case, 3 cases of 7 pts(43%), demonstrated ane or more foci of uptake in post treatment scan, had history of previous radioiodine treatent. Conclusion: Post treatment scan confirmed uptake into remnant and metaststic tissues identified on the corresponding low dose diagnostic scans. Scanning after high dose radioiodine treatment frequently demonstrated one or more foci of uptake, especially in patients with previous radioiodine treatment, which were not visualized on the diagnostic low dose scan. Treatment scan may be useful for detection of remnant tissue or metastatic lesion in patients with elevated thyroglobulin and negative diagnostic scan.
