González Montaño et al: Traumatic pulmonary pseudocysts in nine dogs and two cats
Veterinary Surgery 4, 2023

🔍 Key Findings

  • Traumatic pulmonary pseudocysts (TPP) were diagnosed in 11 patients (9 dogs, 2 cats) using CT after blunt trauma.
  • TPPs were identified on radiographs in 64% of cases that were CT-confirmed, highlighting the superior sensitivity of CT.
  • Most cases (7/10) were managed conservatively, with complete recovery and no TPP-related mortality.
  • Thoracic surgery (lung lobectomy) was performed in 3 dogs, due to persistent pneumothorax or large TPP with perceived risk of complications.
  • All pneumothorax cases were managed with thoracostomy tubes, and chest drains were used in 73% of cases.
  • Pneumothorax was present in 100% of patients, often bilateral, and pulmonary contusions were reported in 73%.
  • One cat was euthanized due to unrelated maxillofacial trauma; no deaths were attributed to TPP itself.
  • Long-term follow-up (median 768 days) revealed only 1 case with possible TPP-related pneumonia; others had no complications.

Multiple Choice Questions on this study

In González Montaño 2023 et al., on traumatic pulmonary pseudocysts (TPP), which imaging modality identified TPPs in all cases?

A. Radiography
B. Ultrasound
C. CT
D. Fluoroscopy
E. MRI

Answer: CT

Explanation: CT identified all TPPs, while radiographs only detected them in 64% of cases.
In González Montaño 2023 et al., on traumatic pulmonary pseudocysts (TPP), which management strategy was used in the majority of TPP cases?

A. Immediate surgery
B. Antibiotics and oxygen only
C. Steroid therapy alone
D. Conservative management with monitoring
E. Thoracic lavage

Answer: Conservative management with monitoring

Explanation: Most (7/10) cases were managed conservatively with full recovery.
In González Montaño 2023 et al., on traumatic pulmonary pseudocysts (TPP), which finding prompted surgical intervention in 3 dogs with TPP?

A. Bilateral contusions
B. Subcutaneous emphysema
C. Diaphragmatic hernia
D. Persistent pneumothorax and risk of rupture
E. Refractory pain

Answer: Persistent pneumothorax and risk of rupture

Explanation: Lung lobectomy was performed in dogs with persistent pneumothorax or large cysts.
In González Montaño 2023 et al., on traumatic pulmonary pseudocysts (TPP), what was the TPP-related mortality in the study cohort?

A. 0%
B. 9%
C. 18%
D. 33%
E. 50%

Answer: 0%

Explanation: No patient died due to TPP; one cat was euthanized due to unrelated trauma.
In González Montaño 2023 et al., on traumatic pulmonary pseudocysts (TPP), what was the most common concurrent thoracic injury in patients with traumatic pulmonary pseudocysts?

A. Rib fractures
B. Pneumothorax
C. Pulmonary laceration
D. Diaphragmatic rupture
E. Pleural effusion

Answer: Pneumothorax

Explanation: Pneumothorax was present in 100% of cases and was often bilateral.
