Abstract

Parathyromatosis is characterized by multiple lesions of benign hyperfunctioning parathyroid tissue in the neck or mediastinum. Parathyromatosis is caused by proliferation of embryonic remnant or seeding of parathyroid tissue after parathyroidectomy. Parathyromatosis is rare but is the common cause of recurrent hyperparathyroidism. We describe a unique case of non-functional parathyromatosis in a 16-year-old girl with a history of right thyroid lobectomy via an axillo-breast approach for a nonfunctioning parathyroid adenoma in the right side of the neck.

Figure

• 

  Fig. 1 Contrast-enhanced dynamic neck computed tomography showed early enhancing mass (arrow) with delayed wash-out in the posterior aspect of the right thyroid gland.

• 

  Fig. 2 A 16-year-old girl with parathyromatosis on ultrasonography. A. Ultrasonography of the anterior neck showed ovoid, homogeneous, and hypoechoic masses (arrows) at the superficial fatty layer of the anterior neck. B. Color Doppler ultrasonography revealed increased vascularity within the masses. Note.-Asterisk = vertebral body of cervical spine

• 

  Fig. 3 A 16-year-old girl with parathyromatosis on contrast-enhanced dynamic neck CT. A-C. Contrast-enhanced dynamic neck computed tomography showed multiple lobulated early enhancing masses (arrows) at the right thyroid lobectomy site, anterior and posterior to strap musculature, and the subcutaneous layer of the anterior neck and left upper chest wall. D. These (arrows) were similarly dense compared to normal left thyroid lobe on delayed CT scan, measuring 2-15 mm in diameter. Note.-Asterisk = left thyroid gland

  Fig. 4 Parathyroid scan showed delayed multiple tracer activities, suggesting parathyroid tissues in the anterior neck and upper chest wall.
