Plain-English summary

A 17-month-old neutered male domestic shorthair cat was brought to the vet because he was having trouble breathing. A special CT scan of his chest revealed serious lung issues caused by heartworm disease, which is caused by a parasite that can infect cats. Despite treatment efforts, the cat's health quickly worsened, and the owners made the difficult decision to euthanize him. A tissue examination confirmed that the cat had heartworm disease, leading to dangerous blood clots in his lungs.

Abstract

A 17-month-old neutered male domestic shorthair cat was referred for a computed tomographic (CT) study of the thorax due to respiratory distress. Multidetector CT angiography showed a multifocal interstitial ground glass opacity, tortuous and blunted pulmonary arteries consistent with thromboembolism with perivascular lung infiltration and hypoventilation in multiple lung lobes. A blood antigen test was positive for Dirofilaria immitis. The cat's clinical condition rapidly declined and the owners elected euthanasia. The histopathologic examination confirmed heartworm disease with parasitic pulmonary thromboembolism.
