The safety of fine-needle aspiration (FNA) of the feline pancreas has not been reported. The incidence of complications following ultrasound-guided pancreatic FNA in 73 cats (pancreatic aspirate [PA] cats) with clinical and ultrasonographic evidence of pancreatic disease was compared with...

Immunohistochemistry (IHC) of tissue samples is considered the gold standard for diagnosing feline infectious peritonitis (FIP), and, in cats without body cavity effusion, IHC is the only method available to establish definitive antemortem diagnosis. However, IHC requires invasive tissue sample...

Case summary: A 9-year-old male neutered Maine Coon cat presented with a 6-month history of polyphagia and one recent episode of tremors and weakness. Blood work revealed profound hypoglycemia and results of a paired insulin glucose test were consistent with an insulinoma. Abdominal ultrasound...

Objective - To determine the accuracy of cytologic diagnosis, compared with histologic diagnosis, in determination of disease in ultrasound-guided fine-needle aspirates of splenic lesions. Design - Retrospective study. Sample Population - Splenic specimens from 29 dogs and 3 cats. Procedures -...

Background: Fine-needle aspirate (FNA) cytology is often the first-choice method for diagnosing gastrointestinal nodular lesions. The FNA material can be converted to histopathology specimens by a needle rinse cell block (NRCB) technique, allowing ancillary studies to refine the cytologic...

A domestic cat was presented for lethargy and coughing. Thoracic radiographs identified a mass within the right cranial lung lobe and a nodule in the left cranial lung lobe. Cryptococcus spp. was diagnosed via ultrasound-guided fine needle aspirate cytology. Despite fluconazole and prednisolone...

Objectives: The primary objective of this study was to retrospectively assess the diagnostic utility of feline renal fine-needle aspiration cytology by assessing diagnostic yield, cytologic characteristics and diagnostic accuracy. The secondary objective was to characterize ultrasonographic...

Ultrasound guidance can be used to facilitate cystocentesis and fine needle aspirates (FNAs) in companion animals. Visualisation of internal structures afforded by the ultrasound probe allows a more accurate and safer collection of fluid or tissue samples for pathological testing. There are many...

Lymph node evaluation is an important component of oncology staging in dogs and cats, however diagnosis of malignancy currently requires cytology or histopathology. Elastography is an ultrasound technique that allows estimation of tissue stiffness. In people, it has been shown to increase the...

Case summary: A 9-year-old, male neutered, indoor-outdoor domestic shorthair cat from the northern Alabama countryside presented for a 3 week history of coughing, lethargy and an episode of self-resolving dyspnea that occurred 1 week prior to presentation. Three-view thoracic radiographs revealed a ...
