Plain-English summary
A 9-year-old neutered male Chihuahua was brought in because the vet suspected he had a diaphragmatic hernia, which is a tear in the diaphragm that can cause breathing issues. However, a CT scan showed a soft tissue mass pressing on his liver, leading to a diagnosis of well-differentiated liposarcoma, a type of tumor made up of fat and soft tissue. This unusual tumor was found to be connected to the diaphragm, which can be a sign of a diaphragmatic tumor. The dog will need further treatment and monitoring to manage this condition.

Abstract
Diaphragmatic tumors are uncommon in veterinary medicine. A 9-year-old neutered male Chihuahua was referred for evaluation of a suspected diaphragmatic hernia. Computed tomography revealed a soft tissue mass with a continuous border to the adjacent diaphragm, compressing the liver caudally. The tumor exhibited hypoattenuating lesions suspected of a mixture of fat and soft tissue. Histopathologic examination diagnosed a well-differentiated liposarcoma. A mass exhibiting a continuous border with the diaphragm and displacement of the adjacent liver may indicate a diaphragmatic tumor. Attenuation indicating a mixture of fat and soft tissue may be a feature of well-differentiated liposarcoma, but further studies on liposarcoma subtypes are needed.
