Summary

Cervical tuberculous lymphadenitis (CTBL) often presents as neck masses. CT scans reveal characteristic low density and thick, irregular rim enhancement, distinguishing it from malignant conditions and abscesses.

Area of Science:

  • Radiology
  • Infectious Diseases
  • Oncology

Background:

  • Cervical tuberculous lymphadenitis (CTBL) is a significant cause of neck masses globally.
  • Accurate differentiation of CTBL from malignant lymphadenopathies and pyogenic abscesses is crucial for effective patient management.

Purpose of the Study:

  • To analyze the computed tomography (CT) findings of CTBL.
  • To compare CT features of CTBL with malignant lymphadenopathies and pyogenic cervical abscesses.

Main Methods:

  • Retrospective review of CT scans from 32 CTBL cases, 25 malignant lymphadenopathies, and 12 pyogenic abscesses.
  • Evaluation of CT parameters including attenuation values, enhancement patterns, and surrounding fat plane integrity.

Main Results:

Related Experiment Videos

  • CTBL demonstrated four types, with Type 3 (multilocular central low densities and peripheral rim enhancement with fat plane obliteration) being most frequent (59.4%).
  • CTBL typically showed thick, irregular enhancing rims, contrasting with thin, regular rims in some malignant nodes.
  • Advanced CTBL (Type 4) exhibited less surrounding fat plane obliteration compared to pyogenic abscesses.

Conclusions:

  • CTBL commonly presents with central low density and thick, irregular peripheral rim enhancement, differentiating it from malignant lymphadenopathy.
  • Multilocular or confluent low densities with peripheral enhancement and less fat plane obliteration suggest advanced CTBL.
