Us Findings

We reviewed the US findings and the diagnostic yield of fine-needle aspiration biopsy (FNAB) for cytologic and microbiologic samples in 4 patients with pulmonary or pleural aspergillosis. All 3 apical Aspergillus abscesses were round, hypoechoic with irregular margins and one contained echo-densities with shadowing consistent with air. One pleural empyema was oval and hypoechoic. Cytology suggested inflammation in all cases and Aspergillus hyphae were detected in 2 of 4 aspirates. Culture of the aspirate was positive for Aspergillus in 3 of 4 cases, while one diagnosis was made after surgery. No complications occurred. Apico-pleural Aspergillus lesions are suitable targets for US-guided FNAB, thus avoiding more invasive methods. Our results suggest wider use of this procedure.

Needle Aspiration Biopsy

Background: Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA) is the preferred method for biopsying the gastrointestinal tract, and rapid on-site cytological evaluation is considered standard practice. Our institution does not perform on-site evaluation; this study analyzes our overall diagnostic yield, accuracy, and incidence of nondiagnostic cases to determine the validity of this strategy. Design: Data encompassing clinical information, procedural records, and cytological assessment were analyzed for gastrointestinal EUS-FNA procedures (n = 85) performed at Vancouver General Hospital from January 2012 to January 2013. We compared our results with those of studies that had on-site evaluation and studies that did not have on-site evaluation. Results: Eighty-five biopsies were performed in 78 patients, from sites that included the pancreas, the stomach, the duodenum, lymph nodes, and retroperitoneal masses. Malignancies were diagnosed in 45 (53%) biopsies, while 24 (29%) encompassed benign entities. Suspicious and atypical results were recorded in 8 (9%) and 6 (7%) cases, respectively. Only 2 (2%) cases received a cytological diagnosis of ‘nondiagnostic'. Our overall accuracy was 72%, our diagnostic yield was 98%, and our nondiagnostic rate was 2%. Our results did not significantly differ from those of studies that did have on-site evaluation. Conclusion: Our study highlights that adequate diagnostic accuracy can be achieved without on-site evaluation.

Objective: Recently the International Academy of Cytology (IAC) proposed a new reporting system for breast fine needle aspiration biopsy (FNAB) cytology. We aimed to categorize our samples according to this classification and to assess the risk of malignancy (ROM) for each category as well as the diagnostic yield of breast FNAB. Study Design: Breast FNAB specimens obtained between January 2007 and December 2017 were reclassified according to the newly proposed IAC Yokohama reporting system. The ROM for each category was determined. Diagnostic yield was evaluated based on a three-category approach, benign versus malignant. Results: The samples were distributed as follows: insufficient material 5.77%, benign 73.38%, atypical 13.74%, suspicious for malignancy 1.57%, and malignant 5.54%. Of the 3,625 cases collected, 776 (21.4%) had corresponding histology. The respective ROM for each category was 4.8% for category 1 (insufficient material), 1.4% for category 2 (benign), 13% for category 3 (atypical), 97.1% for category 4 (suspicious for malignancy), and 100% for category 5 (malignant). When only malignant cases were considered positive tests, the sensitivity, specificity, and diagnostic accuracy were 97.56, 100, and 99.11%, respectively. Conclusions: Our study is the first to categorize breast FNAB cytology samples according to the proposed IAC reporting system and to evaluate patient outcomes based on this categorization.

Needle Aspiration Biopsy

Type 1 autoimmune pancreatitis (AIP) is histologically characterized by lymphoplasmacytic sclerosing pancreatitis (LPSP). Recently, the diagnostic yield of endoscopic ultrasonography-guided fine needle aspiration/biopsy (EUS-FNA/B) for AIP has been reported. However, its role in the diagnostic flow of AIP is not fully elucidated. We retrospectively reviewed 53 consecutive patients who were suspected with AIP and underwent EUS-FNA/B. We evaluated the contribution of EUS-FNA/B to the diagnosis of AIP before considering response to steroid therapy among patients with diffuse enlargement of the pancreas and those with focal enlargement, respectively. Twenty-two patients showed diffuse pancreatic enlargement and 31 showed focal enlargement. The final diagnosis was definitive AIP in 32 patients, probable AIP in 2, possible AIP in 1, and mass-forming focal pancreatitis in 18. There was no change in diagnosis after EUS-FNA/B among patients with diffuse pancreatic enlargement, while diagnosis changed in 38.7% (12/31) among those with focal enlargement—there was a probable to definitive diagnosis in 4 patients, unspecified to definitive in 3, and unspecified to probable in 5. EUS-FNB provided a significantly higher sensitivity for typical pathological findings of LPSP than EUS-FNA, and 10 patients were diagnosed as pathologically definitive AIP by EUS-FNB, though none were by EUS-FNA (p = 0.002). EUS-FNA/B was useful in the diagnosis of focal type AIP, and steroid therapy could be introduced after the diagnosis was confirmed. Meanwhile, EUS-FNA/B provided no contribution to diagnosis of diffuse type AIP. EUS-FNB showed a higher diagnostic yield than FNA.
