摘要

一只 4 岁的雄性混种犬因右侧眶周肿胀和眼球外翻而就诊。头部磁共振成像显示右侧颧腺严重肿大，导致右眼向前方移位，颧腺突出到口腔内。肿大的腺体显示 T2 信号强度增高，并有多个隔膜穿过，脂肪饱和后部分隔膜被抑制。通过侧眶切开术对腺体进行了手术切除。组织病理学检查发现唾液腺脂肪瘤。颧脂肪瘤病在犬中很少发生，在单侧腺体肿大并伴有磁共振成像脂肪浸润的病例中应作为鉴别诊断考虑。本病例强调了磁共振成像（包括脂肪抑制序列）在诊断颅外疾病方面的作用。

Magnetic resonance imaging features of zygomatic lipomatosis in a mixed‐breed dog

A 4‐year‐old, male, entire, mixed breed dog presented with right‐sided periorbital swelling and exophthalmos. Magnetic resonance imaging of the head revealed severe enlargement of the right zygomatic gland, which resulted in anterior displacement of the right eye and protrusion of the zygomatic gland into the oral cavity. The enlarged gland showed an increased T2 signal intensity and was traversed by multiple septae, which partially suppressed after fat saturation. The gland was surgically removed using a lateral orbitotomy. Histopathology revealed a lipomatosis of the salivary gland. Zygomatic lipomatosis occurs rarely in dogs, and should be considered as a differential diagnosis in cases of unilateral gland enlargement with fat infiltration on magnetic resonance imaging. This case highlights the usefulness of magnetic resonance imaging, including fat‐suppressed sequences, for the diagnosis of extracranial diseases.

期刊介绍： Vet Record Case Reports is an online resource that publishes articles in all fields of veterinary medicine and surgery so that veterinary professionals, researchers and others can easily find important information on both common and rare conditions. Articles may be about a single animal, herd, flock or other group of animals managed together. Common cases that present a diagnostic, ethical or management challenge, or that highlight aspects of mechanisms of injury, pharmacology or histopathology are deemed of particular educational value. All articles are peer reviewed and copy edited before publication.
