Born in the Ear Canal: Tick Larva on the Eardrum

Area of Science:

• Otolaryngology
• Parasitology
• Medical Entomology

Background:

• Ear, nose, and throat (ENT) clinics manage various conditions affecting the ear, including infections and obstructions.
• Tinnitus, hearing loss, and ear fullness are common symptoms prompting otological evaluation.

Observation:

• A 54-year-old female patient presented with right-sided hearing loss, tinnitus, and aural fullness.
• Clinical examination revealed a cystic lesion on the tympanic membrane, specifically in the anterior upper quadrant.
• A tick larva was identified within the cystic lesion on the tympanic membrane.

Findings:

• The primary finding was the presence of a tick larva embedded in a cystic lesion on the tympanic membrane.
• This represents a rare and unexpected cause of otological symptoms.
• The diagnosis was unique due to the unusual location and nature of the parasite.

Implications:

• This case underscores the importance of thorough otoscopic examination to identify rare causes of ear symptoms.
• It highlights the need for considering parasitic infestations in differential diagnoses for ear complaints, even in non-endemic areas.
• Early and accurate diagnosis is crucial for appropriate management and to prevent potential complications from the parasitic infestation.
