title: Giant cystic parathyroid adenoma with thrombosis of internal jugular vein seen on CT and Tc-99m methoxy isobutyl isonitrile parathyroid scan.
abstract: Primary hyper-parathyroidism is attributed by a solitary parathyroid adenoma in 80-85% cases and mostly are non-palpable and needs imaging for localization. Cystic degeneration of parathyroid adenoma is rarely seen in primary hyperparathyroidism. We are presenting a case of giant cystic functioning parathyroid adenoma with associated localized co-morbids.
