Ectopic intrapulmonary thyroid masquerading as metastatic carcinoma of the lung: a rare case scenario.

ABSTRACT

BACKGROUND: The intrapulmonary ectopic thyroid gland is exceedingly rare since the ectopic thyroid was discovered. Only eight cases have been reported in the worldwide literature. We present a case of multiple intrapulmonary ectopic thyroid glands with nodular goiter in a 10-year-old girl. CASE PRESENTATION The girl was found with multiple intrapulmonary nodules in bilateral lungs during the treatment of nodular goiter. The intrapulmonary lesions were initially thought to be a high possibility of metastatic cancer. A computed tomography-guided percutaneous lung biopsy was performed, and the pathological examination confirmed that the diagnosis was ectopic intrapulmonary thyroid. CONCLUSION: The ectopic intrapulmonary thyroid should be considered when children with nodular goiter presenting with suspected metastases in the lung.
