To investigate the application value and the key technique of ultrasound-guided percutaneous biopsy of neck lymphadenopathy by freehand.
Methods:
Forty-two patients with neck lymphadenopathy of unknown cause from March 2011 to March 2013 underwent ultrasound-guided percutaneous biopsy using 18 G or 16 G tissue biopsy needle by freehand
The size of 1ymph nodes was 1.0 cm0.6 cm-8.6 cm5.0 cm. Each patient was punctured 2 to 5 times
A biopsy was considered technically successful if a targeted tissue was obtained and it could meet the requirement of qualitatively pathologic diagnosis.
Results
: The rate of technically successful biopsy which could meet the requirement of qualitatively
pathologic diagnosis was 92.9%
The pathological results showed that lymph nodes in 12 patients (28.6%) were malignant
including metastatic carcinoma in 7 patients and malignant lymphoma in 5 patients
while lymph nodes in 26 patients (61.9%) were benign
including tuberculous lymphadenitis in 14 patients
reactive hyperplasia in 5 patients
chronic granulomatous inflammation in 4 patients and histiocytic necrotizingly lymphadenitis in 3 patients. There was one case with uncertainty (2.4%).
Conclusion:
Ultrasound-guided percutaneous biopsy by freehand is real-time
accurate
flexible and minimally invasive. It has high value in diagnosis of cervical lymphadenopathy.
