abnormality, an ultrasound and a computed tomography were performed which showed a right aberrant subclavian artery with a retroesophageal course and a common trunk of the common carotids in both patients. Discussion and Conclusion: The presence of an NRLN is a major risk during surgical procedures and the surgeon should be aware of the possibility of its existence. NRLN may be associated with rare vascular anomalies, such as arteria lusoria and a bicarotid trunk. This paper reveals this association in 2 patients for the first time.
Key Words Recurrent laryngeal nerve · Thyroid surgery · Vascular anomalies · PredictionAbstract Introduction: A nonrecurrent laryngeal nerve (NRLN) is a rare anatomical variation in which the nerve enters the larynx directly off the cervical vagus nerve. Case Report: We present 2 patients who underwent thyroid surgery for benign disease. Intraoperatively, type 2a and 1 NRLN were identified. Due to the frequent association with a vascular
Practice of Iberian endocrine surgeons is consistent with current recommendations on surgery for primary hyperparathyroidism, with variability in some areas.
SUMMARYThyroid metastases are rare in clinical practice. We describe the case of an 85-year-old woman who was referred to our department due to a multinodular goiter with compressive symptoms and subclinical hyperthyroidism. The patient was also undergoing evaluation for a polyp in her left nasal cavity, which was then diagnosed as a malignant melanoma of the nasal mucosa. A thoracoabdominal magnetic resonance imaging obtained for cancer staging revealed a > 50% tracheal obstruction caused by the goiter. The patient underwent simultaneous total thyroidectomy and melanoma excision. Histological analysis of the thyroid showed the presence of multiple metastatic foci from the melanoma. Due to the patient's age, a decision was made to maintain her under surveillance and administer palliative treatment if necessary. Although metastases to the thyroid are rare, they should be considered in the differential diagnosis of thyroid lesions in patients with a known primary tumor. The thyroidectomy, performed in this patient's case, allowed the diagnosis of the metastases and relief of compressive symptoms caused by the goiter. Arch Endocrinol Metab. 2017;61(2):193-7.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
