Abstract

Ectopic parathyroid adenomas are a common cause of postsurgical persistent primary hyperparathyroidism. Our case highlights a patient with a negative bilateral 4-gland exploration with follow-up parathyroid 4-dimensional CT and Tc-MIBI SPECT/CT, yielding focal uptake in the right piriform sinus. Subsequent direct laryngoscopy revealed a mass in the piriform sinus, which was resected with surgical pathology yielding parathyroid adenoma.

摘要

甲状旁腺腺瘤是术后持续性原发性甲状旁腺功能亢进的常见原因。我们的病例突出了一位双侧 4 腺探查阴性的患者，随后进行了甲状旁腺 4 维 CT 和 Tc-MIBI SPECT/CT 随访，发现右侧梨状窦有局灶性摄取。随后的直接喉镜检查显示梨状窦内有一肿块，手术切除后病理检查为甲状旁腺腺瘤。
