Introduction:
Parathyroid cysts are infrequently encountered and have a variable presentation pattern depending on their size, location and secreting character.
Patients And Methods:
We report two cases of parathyroid cysts characterized by their uncommon clinical presentation.
Results:
In the first case the patient presented with a large cervical cystic mass without hypercalcemia, while in the second case, the patient experienced a hypercalcemic crisis associated with acute renal failure. The variable pattern of clinical manifestations is discussed.
Conclusion:
Parathyroid cysts are a rare entity. Surgical resection is the key to therapy when hyperparathyroidism or local compression are identified.

z Scores and Unusual Values
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...
