Role of contrast enhanced ultrasound guidance in core needle biopsy for diagnosis of cervical tuberculous
mycobacterial lymphadenitis

T
o investigate the role of core-needle biopsy (CNB) guided by contrast-enhanced ultrasound (CEUS) played in the diagnosis
for cervical tuberculous mycobacterial lymphadenitis (TML). One hundred and seventy one lymph nodes in 171 patients with
pathological confirmation of TML were retrospectively enrolled. All had undergone CNB before the final surgery. The patients were
assigned to either conventional ultrasound guided CNB group (n=87) or CEUS guided CNB group (n=84). The comparison of two
groups on diagnostic efficacy in terms of sensitivity was statistically made. Subgroup analyses on lymph node size were performed
furthermore. Among the 171 patients, one hundred and forty one patients were directly diagnosed to be TML in CNB, which were
consisted by 77 patients in CEUS- guided CNB group and 64 patients in conventional ultrasound guided CNB group. The sensitivities
were 91.7% (77/84) and 73.6% (64/87), respectively (p<0.05). As to subgroup analyses, differences among sensitivities caused by the
two guiding methods were significant in medium size group (i.e. diameter was 2.0-3.0 cm) and large size group (i.e. diameter was
larger than 3.0 cm), 93.1% for CEUS group vs. 74.2% for conventional ultrasound group (p<0.05) and 85.7% for CEUS group vs.
57.1% for conventional ultrasound group (p<0.05), respectively. However, no significant difference was found in small size group (i.e.
diameter was smaller than 2.0 cm) (96.3% for CEUS group vs. 92.9% for conventional ultrasound group, p=0.57). Comparing with
conventional ultrasound guided CNB, further benefits could be gained through CEUS guided CNB in TML diagnosis, especially for
those whose diameter was larger than 2.0 cm.
