Computed tomography versus ultrasound/fine needle aspiration biopsy in differential diagnosis of thyroid nodules: a retrospective analysis

ConclusionComputed tomography examinations are a more reliable method for differential diagnosis of thyroid nodules than ultrasound examinations followed by fine needle aspiration biopsy.Level of EvidenceIII.ResumoIntroduçãoA ultrassonografia é um método rápido para determinar de qual nódulo deve-se coletar uma amostra para biópsia por aspiração com agulha fina. Por outro lado, o exame de tomografia computadorizada não é restringido pela atenuação do eco e distingue entre nódulos benignos e malignos.ObjetivoComparar exames tomográficosversus biópsia por ultrassonografia / aspiração por agulha fina no diagnóstico diferencial de nódulos tireoidianos.MétodoDados sobre exames tomográficos, achados ultrassonográficos após biópsia por aspiração com agulha fina e histologia tumoral de 953 nódulos de 698 pacientes submetidos à tireoidectomia foram coletados e analisados. O escore de benefício para detecção do tumor maligno para cada modalidade adotada foi avaliado.ResultadosAs imagens de ultrassom não mostraram uma lesão sólida bem circunscrita em 89 nódulos; e na análise final, não foram detectados nódulos nas biópsias por aspiração com agulha fina (nódulos não-malignos falsos pos...

ConclusionResection is the most suitable therapy for clinical symptoms of a foreign body in the upper aerodigestive tract and inflammatory complications; total thyroidectomy follows in case of malignant transformation. Thyroid heterotopy is a rare pathological condition, yet it should be taken into consideration during differential diagnosis of tumorous oropharyngeal and neck lesions.

Conclusion: PSCCT is a rare but aggressive malignancy of the head and neck. Histopathologic and immunohistochemical evaluations are essential for diagnosis. While locoregional surgery and radiation therapy may improve the length of survival, the prognosis of patients with PSCCT is poor. Physicians should be mindful of this unique but deadly disease process, as early diagnosis and rapid treatment initiation are essential to optimize treatment outcomes. PMID: 31528145 [PubMed]

CONCLUSIONMalignant pancreatic nerve sheath tumours are very rare to be found, but have very poor prognosis, hence in cases of pancreatic tumour its better to keep the diagnosis of nerve sheath tumour also a differential diagnosis. In conclusion pancreatic tumours are to be identified at the earliest and surgery should be done for those cases

Abstract BACKGROUND: Medullary thyroid cancer (MTC) accounts for 5% of all thyroid cancers and occurs either sporadically or in a hereditary pattern. Routine calcitonin (CT) measurement is suggested for MTC screening in patients with nodular thyroid disease. Patient Findings A 45 years-old woman incidentally discovered, with neck ultrasound, the presence of thyroid micronodules. Fine-needle aspiration (FNA) on thyroid prevailing nodule did not demonstrate cellular atypia. During follow-up, FNA was repeated on the previously analyzed nodule suspicious for Hürthle cell nodule suspicious for follicular neoplasm ...

We present the case of an 81‐year‐old man with past medical history of PTC status post total thyroidectomy with local recurrence treated with radioactive iodine and selective neck dissection. Ten years after his initial diagnosis, PET‐CT scan revealed a new hypermetabolic 1.1 cm × 0.9 cm left lower lobe lung nodule and hypermetabolism in the proximal body of the pancreas. Follow‐ up MRI cholangiogram showed a 1.0 × 0.8 cm T1 hypointense lesion in the proximal body of the pancreas. Endoscopic ultrasound‐guided fine‐needle aspiration biopsy of the pancreatic mass showed neoplastic epithelial cells arr...

CONCLUSION: Thyroid gland suppuration is a very infrequent circumstance in neck pathology, and the options for its treatment are varied, from conservative to invasive techniques according to the microbial and radiologic findings. PMID: 29891396 [PubMed - as supplied by publisher]

Wong Lateral neck lymph node metastases in well differentiated thyroid cancer are common, ranging from 30-60%, with the majority of these foci identifiable only as microscopic deposits. A skilled ultrasound evaluation of the lymph nodes in the lateral neck is recommended for all patients presenting with newly diagnosed thyroid cancer undergoing surgical management. Ultrasound guided fine needle aspiration biopsy may be used to cytologically confirm suspected lateral neck nodal m...
