At Northumberland Referrals, we can also help with complex soft tissue cases 🐾
Keep reading for an interesting case — and a very satisfying video! 👀
Tabitha, a 3-year-old cat, was referred to us with a three-month history of persistent right ear discharge, despite antibiotic treatment. During otoscopic examination, a mass was identified within the ear canal. 🐈
MRI confirmed a large, contrast-enhancing mass involving the right vertical and horizontal ear canals (blue arrows) and extending into the right tympanic bulla. Also it was noticed thickened epithelium in the right caudomedial chamber (red arrows).
Tabitha underwent a ventral bulla osteotomy, a surgical procedure that allows access to the middle ear. The mass was successfully removed along with the thickened epithelium. Histopathology confirmed it to be an inflammatory aural polyp🔬
Feline inflammatory aural polyps are benign, non-cancerous masses that usually originate within the middle ear or Eustachian tube. Depending on the direction in which they grow, they can cause significant ear or upper airway disease. Chronic inflammation, potentially associated with viral infection, has been proposed as one possible contributing factor. 🦠
When a polyp extends from the middle ear into the external ear canal, affected cats may develop signs such as persistent ear discharge or Horner’s syndrome.
If it grows through the Eustachian tube into the nasopharynx, signs can include stertor, nasal discharge, dysphagia and, in more severe cases, upper airway obstruction.
If not treated, as the polyps grow within the confined space of the middle ear, they can also lead to more serious complications, including peripheral vestibular signs such as a head tilt, nystagmus and loss of balance. ⚠️
Secondary infections can also develop within the middle ear. In rare, severe cases, bacterial meningitis can occur if the infection spreads to the central nervous system. This makes early diagnosis and appropriate treatment particularly important. 🧠
Thankfully, Tabitha made a fantastic recovery following surgery! 💚 🐱
