Lymph Node Abscessation Secondary to Neoplasia in Two Dogs

Figure 1

Transverse plane CT images of the left medial retropharyngeal lymph node abscesses. Case 1 (a) demonstrates severe lymphadenomegaly, with minimal peripheral contrast enhancement, and multiple intraluminal gas bubbles. Case 2 (b) demonstrates severe lymphadenomegaly, with peripheral contrast enhancement, as well as central septations that had similar contrast enhancement. Both cases have soft tissue stranding in the adjacent soft tissues and cause rightward deviation of the larynx. The contralateral medial retropharyngeal lymph node is labelled with an asterisk (). Notice that both medial retropharyngeal lymph nodes are bordered medially by the common carotid (arrowhead) and laterally by the mandibular salivary gland (cranially displaced by the mass in case 2).
