< Back Computer Tomography (CT) Scan Case Study #8 拉布拉多犬 Labrador Retriever
Labrador Retriever, female, 11 years old
Clinical History:
1-2 day onset of left side upper face swollen
Findings:
There is soft tissue thickening and contrast enhancement associated with the left side of the maxilla.
This swelling is centred around the 4th premolar on the left side. This tooth exhibits focal lysis within the alveolar bone around the tip of the caudal tooth root. This lysis has breached the lateral cortex of the maxilla resulting in a direct communication between this tooth root and the external soft tissues.
There is pulp cavity exposure within this tooth as there appears to be a fragmentation of the crown laterally.
There is mild enlargement of the left mandibular and medial iliac lymph nodes when compared to the right.
Conclusion:
1) Focal tooth root abscess on the caudal root of the left maxillary 4th pre-molar
2) Secondary soft tissue thickening and swelling due to extension of the infection outside of the maxilla
3) Local lymphadenopathy
The soft tissue lesion on the maxilla appears to be directly related to the focal dental lesion within the maxillary bone. There is a direct extension of this tooth root infection into the adjacent soft tissues.
Extraction of the left 4th premolar and appropriate antibiosis is recommended to help address this infection and resolve the clinical findings. The local lymphadenopathy is most likely reactive.
There is no evidence of neoplasia within this study. The soft tissue swelling has an obvious infectious cause and the lung lobes showed no evidence of nodular change.
