Atypical non-[99mTc]Tc-MIBI avid parathyroid adenoma with a sternal brown tumor, mimicking ectopic parathyroid adenoma in planar and SPECT images: Importance of SPECT/CT acquisition
Primary hyperparathyroidism (pHPT) is defined by the excess level of parathyroid hormone (PTH). Parathyroid adenoma is responsible for about 80% of all pHPT. Parathyroid adenoma with cystic feature and atypical pathology is recognized as a rare entity. Technetium-99m methoxy isobutyl isonitrile ([99mTc]Tc-MIBI) scintigraphy has favorable detection rate for ectopic gland as well as th...
متن کاملAbsent radiotracer uptake in thyroid gland in parathyroid scintigraphy with 99mTc-MIBI: A case report
Localization of 99mTc- hexakis-2-methoxyisobutylisonitrile (99mTc-MIBI) by parathyroid adenomas is well known, and this warrants MIBI scan to evaluate suspected parathyroid adenoma in primary hyperparathyroidism. Typically, the radionuclide concentrates in both the thyroid gland and parathyroid adenoma in early images, and later on delayed images washes out slowly from the...
متن کاملSignificance of MIBI scintigraphy in a patient with hydatid cyst and parathyroid adenoma
A 17-year-old boy with hyperparathyroidism exhibited a large cyst in the left hemi-thorax on his chest X-ray. The cyst was identified as a hydatid cyst. He was referred for biphasic methoxy isobutyl isonitrile (MIBI) parathyroid scan. A discrete ectopic parathyroid was detected in the left upper mediastinum in addition to accumulation of the MIBI tracer in the cyst wall. Using radio-guided occu...
متن کاملLocalization of ectopic parathyroid adenoma with Tc-99m-MIBI [Persian]
Ectopic paratliyroid adenoma might create a clinical dilemma in patients with hypercalcemia. Radioisotopic scan is a sensitive and noninvasive method which can be useful in these patients. In this report a case of ectopic parathyroid adenoma is presented and the usefulness of TC-99m-MIBI scintigraphy as compared with other modalities is discussed.
متن کاملNegative 99mTc-MIBI uptake in a parathyroid carcinoma: A case report
A 34 year old woman with malaise, polyuria and nocturia as well as nausea and vomiting referred to perform a thyroid scan due to right thyroid lobe mass. The scan showed a cold nodule in the right thyroid lobe. Serum calcium of 16.9, serum phosphorus of 1.8 and PTH of 1156 were noticed in laboratory tests. Parathyroid scan with 99mTc-MIBI showed no abnormal tracer activity in the nec...
