Giant intrathyroidal parathyroid cystic adenoma.
J Pak Med Assoc Jan ;58(10):592.

We came cross a-35-year old male patient who was admitted to our hospital with the main complaint of aching joints and fatigue. He had no history of any surgery, drug or alcohol usage or any diagnosed disorder. On physical examination a palpable mass at his right thyroid lobe was found. Relevant laboratory findings were serum calcium level 12.3 mg/dL, phosphuros 1.6 mg/dL, albumin 3.8 g/dL, TSH 2.1 µU/ml, alkaline phosphatase 164 UI/L (normal range 40-100 UI/L), intact PTH (iPTH) 285 pg/ml (normal range 15-65 pg/ml), and 25 OH vitamin D levels of 18 ng/ml (normal range 14- 39.3 ng/ml). Haemogram and renal function values were normal. Ultrasonographic examination was reported as a 5 x 3 x 2cm cystic nodule at right thyroid lobe (Figure.1a). Technetium-99 (Tc-99) sestamibi seintigraphy revealed an area of increased tracer uptake at the nodule, which was suggestive of its parathyroid origin. A surgical exploration was planned. During operation a giant parathyroid adenoma was excised.
