RESUMO
Background/Objective: Occult papillary thyroid carcinoma (PTC) is PTC with metastasis but without identification of primary thyroid cancer on preoperative ultrasonography. Published reports on occult PTC in children are limited. Case Report: We describe a 16-year-old female with occult PTC who initially presented with a painless left sided cystic neck mass. Diffuse sclerosing variant papillary thyroid cancer was found in the resected neck mass and thyroid ultrasound did not show any nodules or features of carcinoma. After total thyroidectomy, pathological examination of the thyroid revealed papillary thyroid microcarcinoma. Discussion: We describe a rare case of occult diffuse sclerosing variant papillary thyroid cancer presenting as a cystic neck mass mimicking a second branchial cleft cyst in an adolescent patient. When metastatic PTC is found without evidence of nodule on thyroid imaging, occult PTC of the thyroid is the likely diagnosis. Conclusion: Total thyroidectomy ± neck dissection followed by TSH suppression and radioactive iodine therapy remains the appropriate diagnostic and therapeutic interventions.
RESUMO
BACKGROUND: This retrospective case report describes a rare presentation of VBI in a young male patient. AIMS: Share a rare cause of VBI in a young patient. MATERIALS & METHODS: The patient presented with recurrent episodes of dizziness and a history of several cerebellar infarcts. Imaging revealed the right vertebral artery was being mechanically compressed by the right superior cornu of the thyroid cartilage during mouth opening. Surgical resection of the right superior cornu of the thyroid cartilage was performed. RESULTS: Intraoperative angiography revealed a right vertebral artery without compression during mouth opening. DISCUSSION: Clinicians should consider the thyroid cartilage as a potential source of recurrent VBI due to mechanical compression of the VA. CONCLUSION: Resection of the causative portion of the thyroid cartilage resolved the compression in this case, and should be employed in similar cases. Laryngoscope, 133:1214-1217, 2023.
