OBJECTIVE Computed tomography-guided percutaneous fine needle aspiration biopsy of lung lesions is a simple, safe and reproducible procedure. Currently, it is widely used to diagnose lung lesions. However, different factors can influence the success rates of this procedure. The purpose of this study was to determine the influence of radiological and procedural characteristics in predicting the ...

CONTEXT Endoscopic ultrasound has proved to be an invaluable tool when obtaining high quality images of the pancreas. Furthermore, fine-needle aspiration of suspected lesions can be carried out simultaneously thus providing tissue samples for cytologic diagnosis. We present two cases of a rare pancreatic lesion that were diagnosed by endoscopic ultrasound with fine-needle aspiration. CASE #1: A...

BACKGROUND Good cytological sample is very important for the cytological diagnosis of thyroid nodules. The aim of this study was to evaluate the adequacy of prepared samples by the combination of aspiration and non- aspiration fine needle biopsy. METHODS In this descriptive - analytical study, sampling was done simultaneously for each patient in fine needle aspiration and non-aspiration biops...

Giant cell tumor of soft tissue is an uncommon neoplasm. To our knowledge, its cytopathology obtained using the fine-needle aspiration biopsy technique has not been previously described. We report an example of the fine-needle aspiration cytology of giant cell tumor of soft tissue in a 40-year-old woman, and correlate it with the corresponding tissue specimen.

Endoscopic ultrasonography guided fine needle aspiration is a useful diagnostic aid in evaluation of cystic pancreatic mass. We report our patient with pancreatic tuberculous abscess who presented with pyrexia, and was found to have cystic pancreatic mass on CT scan. Pancreatic tuberculous abscess was diagnosed with the help of endoscopic ultrasound (EUS)-guided fine needle aspiration cytology ...

56 malignant bone neoplasms (15 primary and 41 metastatic), diagnosed by fine-needle aspiration biopsy, are reported. 100% diagnostic accuracy was achieved. The results indicate that fine-needle aspiration biopsy can be a substitute for open surgical biopsy in selected cases.

A 46-year-old man presented with shock and adult respiratory distress syndrome. Investigations revealed an adrenal mass that was diagnosed, by fine-needle aspiration biopsy, as pheochromocytoma. Because biopsy is contraindicated in patients with pheochromocytoma, this confusing presentation underscores the value of excluding this diagnosis by biochemical means before performing fine-needle aspi...

Fine needle aspiration cytology has undergone increasing utilization in the evaluation of hepatic neoplasms. Experience with liver aspirates has demonstrated that problems in differential diagnosis require thorough understanding of criteria for distinguishing different tumor types. The present report describes the cytologic presentation of primary and metastatic hepatic tumors with emphasis on ...

Bronchoscopic transbronchial fine needle aspiration of the mediastinum is generally known as a safe procedure. Complications such as pneumothorax, pneumomediastinum, major bronchial haemorrhage and significant bleeding after a major vessel puncture are rare events. We report the first case, to our knowledge, of life-threatening cardiac tamponade following transbronchial fine needle aspiration i...

Background: Thyroid nodules are a common problem which requires an accurate cytological diagnosis for proper management. An essential investigation modality is fine needle aspiration cytology (FNAC) with a sensitivity ranging between 80-90%. Recommendations vary regarding the use of ultrasound in improving the accuracy of free hand fine needle aspiration biopsy. Objective: The aim of our study ...
