Parathyroid incidentaloma.

Incidentalomas are lesions which are asymptomatic and detected incidently during imaging or surgery. Parathyroid incidentalomas are a rare entity. Enlargement of gland without hyperfunction may be an early stage of disease. Symptomatology is usually non-specific or related to renal and skeletal system. Total serum calcium estimation may be used as a screening modality. Sestamibi scan is a more accurate imaging technique than USG. FNAB - PTH measurement is the most reliable minimally invasive nonsurgical test for parathyroid tissue verification. Incidently discovered enlarged parathyroid gland may be removed to avoid a re-do surgery.
