Abstract
Aim
Ultrasound-guided biopsy technique with the large-core needle has widely been applied in the diagnosis of adult abdominopelvic cavity, thyroid, and neck tumors. There are few reports on ultrasound-guided biopsy using large-core needle in pediatric abdominopelvic cavity tumors. This study was to evaluate the ultrasound features and the diagnostic value of ultrasound-guided core needle biopsy for pediatric neuroblastic tumors.
Methods
The pediatric patients with neuroblastic tumor that underwent ultrasound examination and ultrasound-guided core needle biopsy from January 2009 to November 2015 were reviewed. A minimum of two cores in each case was obtained. The biopsy results were confirmed by subsequent surgical histopathology. The ultrasound features and the diagnostic accuracy of ultrasound-guided core needle biopsy were evaluated.
Results
Eighty-three patients were enrolled into the study. Conventional ultrasound examination showed irregular hypoechoic or mixed echo masses and calcification and liquefied necrosis. The diagnostic accuracy of ultrasound-guided core needle biopsy was 96.4% (80/83). Three cases were misdiagnosed because of inadequate tissue sample. No serious complication, infection, or needle track seeding occurred.
Conclusions
Ultrasound-guided core needle biopsy seems to be an accurate, minimally invasive, and safe diagnostic method of pediatric neuroblastic tumor.
