Cervical lymph node metastasis is common in patients with papillary thyroid carcinoma (PTC).Salmonellaspecies are rarely reported as causative agents in focal infections of the head and neck. The cooccurrence of lymph node metastasis from PTC and a bacterial infection is rare. This report describes a 76-year-old woman with a cervical lymph node metastasis from PTC andSalmonellainfection of the same lymph node. The patient presented with painful swelling in her left lateral neck region for 15 days, and neck ultrasonography and computed tomography showed a cystic mass along left levels II–IV. The cystic mass was suspected of being a metastatic lymph node; modified radical neck dissection was performed. Histopathological examination confirmed the presence of PTC in the resected node and laboratory examination of the combined abscess cavity confirmed the presence ofSalmonella Typhi. Following antibiotic sensitivity testing of the culturedSalmonella Typhi, she was treated with proper antibiotics. Cystic lesions in lymph nodes with metastatic cancer may indicate the presence of cooccurring bacterial infection. Thus, culturing of specimen can be option to make accurate diagnosis and to provide proper postoperative management.

Abstract BackgroundThe prediction of ipsilateral lateral cervical lymph node metastasis (ipsi-LLNM) was crucial to the operation plan in patients with papillary thyroid carcinoma (PTC). This study aimed to investigate the risk factors for ipsi-LLNM using dual-energy computed tomography (DECT) and thyroid functional indicators in patients with PTC. MethodsThe medical records of 406 patients with a pathological diagnosis of PTC were retrospectively reviewed from Jan 2016 to Dec 2019. Demographic, clinical, pathological findings, and parameters from DECT were evaluated. Risk factors for ipsi-LLNM were explored by univariate and multivariate analyses. Receiver operating characteristic (ROC) curves were used to evaluate the cut-off value of each risk factor.ResultsTotally 406 patients with PTC were analyzed, including 128 with ipsi-LLNM and 278 without. There were statistical differences of parameters between the two groups (P < .0001), including serum Tg, Anti-Tg, Anti-TPO, the volume of the primary lesion, calcification, extrathyroidal extension (ETE), and iodine concentration (IC) in arterial and venous phases. Independent risk factors for ipsi-LLNM included serum Tg, Anti-Tg, ETE, and IC in arterial and venous phases (P < .05). Ipsi-LLNM was more likely to occur when the following conditions were met: with ETE, Tg > 100.01 ng/ml, Anti-Tg > 89.43 IU/ml, IC in arterial phase > 3.4 mg/ml and IC in venous phase > 3.1 mg/ml.ConclusionsApplication of DECT parameters and thyroid functional indicators can improve the diagnostic performance in the evaluation of ipsi-LLNM in patients with PTC.
