Key result
Pulmonary tumor embolization from pheochromocytoma triggers sudden death in a canine case report.
Why the study?
Tumor embolization is a well-described cause of unexpected death in human oncologic patients, but it is poorly explored in veterinary medicine.
Case Report (n=1)
Tumor embolization should be considered as a possible cause of sudden death in dogs, particularly in oncologic patients.
Alerts clinicians to embolization risk in dogs with adrenal tumors; leaves open its prevalence and predictors in veterinary practice.
Tumor embolization is a well-described cause of unexpected death in human oncologic patients; however, it is poorly explored in veterinary medicine. We report a case of pulmonary tumor embolization in a dog with sudden death. During necropsy, a neoplastic mass was observed replacing the left adrenal gland and forming an intravascular thrombus within the central adrenal vein. A large embolus occluded the left pulmonary artery. The adrenal mass was histologically confirmed as a pheochromocytoma, and the embolus was constituted of neoplastic cells. Multiple smaller neoplastic emboli were observed within the pulmonary artery branches. Tumor embolization should be considered as a possible cause of sudden death in dogs, particularly in oncologic patients.

Aguiar et al. (2023) conducted a case report in Pulmonary tumor embolism / Pheochromocytoma (n=1). Pulmonary tumor embolization was evaluated on Sudden death and necropsy findings. Pulmonary tumor embolization from a pheochromocytoma was identified as the cause of sudden death in a dog, highlighting it as a potential cause of unexpected death in veterinary oncologic patients.
