A 9-year-old Maine coon cat presented with right-sided Horner and facial nerve paralysis. Magnetic resonance imaging (MRI) showed a heterogeneously contrast-enhancing mass occupying the right dorsolateral compartment of the tympanic cavity and extending into the ventromedial compartment, which was expanded and fluid filled. A ventral bulla osteotomy was performed to debulk the soft tissue mass. Histopathology revealed a cholesteatoma. The cat showed slow improvement of clinical signs and was euthanized eleven months postoperatively for unrelated causes. The MRI characteristics of middle ear cholesteatoma in the present case varied from those described in humans and dogs.
一只 9 岁的缅因浣熊猫出现右侧霍纳氏综合征和面神经瘫痪。磁共振成像（MRI）显示一个不均匀增强的肿块占据了鼓室的右外侧隔室，并延伸到腹内侧隔室，该隔室扩大并充满液体。进行了腹侧鼓泡切开术以去除软组织肿块。组织病理学显示胆脂瘤。这只猫的临床症状改善缓慢，术后 11 个月因与本病无关的原因被安乐死。本病例中耳胆脂瘤的 MRI 特征与人类和狗的描述不同。
