A 51-year-old female complained of neck swelling and shortness of breath. Physical examination revealed a large left-sided, non-tender lobe of the thyroid, whose lower pole was not palpable, with a positive Pemberton's sign.
She was biochemically euthyroid, but incidentally found to have hypercalcemia with an elevated parathyroid hormone (PTH) level. Computed tomography revealed a large mass (6.4 cm × 5.2 cm × 8.2 cm) occupying the left-lobe of the thyroid extending into the thoracic-inlet causing tracheal and esophageal compression and deviation (Figure 1, Panel A). Sestamibi scan revealed a large left thyroid lobe with homogenous uptake. No abnormal parathyroid lesion was localized (Figure 1, Panel B).
The patient underwent a left-sided lobectomy and removal of an enlarged parathyroid gland. The specimen comprised of the left-lobe of the thyroid measuring 7.0 cm × 8.5 cm × 5.0 cm (Panel C). A solid mass was seen occupying most of the thyroid lobe. Pathological analysis confirmed a benign follicular adenoma of the left lobe. Post-operative calcium and PTH levels normalized and all symptoms resolved. She remained euthyroid on follow- up.
