BACKGROUND AND PURPOSE Tuberculous lymphadenitis and metastatic nodes from nasopharyngeal carcinoma are common in Asians and are often indistinguishable clinically. Because their treatment depends on prompt diagnosis, we undertook this study to evaluate if power Doppler sonography could distinguish these two pathologic abnormalities. The intranodal vascular appearances of tuberculous neck nodes...

clinically apparent cervical lymphadenopathy has been found at the initial presentation in 23 to 56 % of cases of papillary thyroid carcinoma. here we report tuberculous lymphadenitis mimicking metastatic lymph nodes from papillary thyroid carcinoma and suggest that tuberculosis apart from metastasis in papillary thyroid carcinoma should also be considered in the etiology of enlarged lymph node...

BACKGROUND In patients with head and neck squamous cell cancer, metastases in cervical lymph nodes still remain the single most important negative predicting factor. Their presence reduces overall 5-year survival by 50%. The aim of the study was to evaluate the role of computed tomography perfusion (CTP) for differentiation between metastatic and non-metastatic cervical lymph nodes in patients ...

OBJECTIVES To assess the performance of contrast-enhanced ultrasound (CEUS) intended to differentiate hyperplastic from malignant neck lymph nodes in an animal model. METHODS Twenty-four New Zealand rabbits were randomly divided into two groups: neck lymph node metastasis group (12 rabbits) and reactive hyperplastic lymph node group (12 rabbits). Tongue VX2 carcinoma with cervical lymph node ...

OBJECTIVE To evaluate the usefulness of measuring the apparent diffusion coefficient (ADC) in diffusion-weighted magnetic resonance imaging to distinguish benign from small, non-necrotic metastatic cervical lymph nodes in patients with head and neck cancers. MATERIALS AND METHODS Twenty-six consecutive patients with head and neck cancer underwent diffusion-weighted imaging (b value, 0 and 800...

IMPORTANCE Central neck dissection (CND) is considered an imperative part of the treatment of patients with high-risk, well-differentiated thyroid carcinoma. OBJECTIVE To examine the presence of lymphatic tissue and/or metastatic nodes in the upper part of the paratracheal region to determine the need to dissect this region as part of a paratracheal neck dissection. DESIGN, SETTING, AND PAR...

UNLABELLED The removal of level II, III, and IV metastases has gained importance in the treatment of squamous cell carcinomas (SCC) of the neck and larynx. This study assessed the possibility of removing level II and level III metastases only, given the low likelihood of occurrence of metastatic lymph nodes on level IV in SCCs of the larynx. OBJECTIVE This study aimed to analyze the prevalenc...
