Skull base osteomyelitis with secondary cavernous sinus thrombosis: a rare presentation of an animate foreign body in the ear

A 42-year-old woman presented with fever, left ear pain, restricted mouth opening, difficulty in swallowing and inability to open her left eyelid for a period of 10 days. She was treated with antibiotics for the same at a local medical facility; however, a sudden decrease in her left eye vision prompted her to visit our tertiary centre. Her history was insignificant except for having multiple left ear syringing for an insect removal 10 days before onset of her current symptoms. On examination, she had ptosis of the left eye with chemosis, dilated pupil with only perception of light and restricted ocular mobility. Oral examination revealed trismus and bulge in the left peritonsillar region. Left ear examination revealed a large central perforation with mucopurulent discharge. CT of the neck with contrast demonstrated a collection in the left peritonsillar space with left internal carotid artery thrombosis. MRI of the brain with gadolinium revealed left cavernous sinus thrombosis with acute infarcts in the left frontal lobe. An emergency incision and drainage of the left peritonsillar abscess was performed. Culture grew broad aseptate fungal hyphae. Despite starting on antifungal therapy, she succumbed to her illness.
