Plain-English summary
A 6-month-old female Boxer was brought to the vet because she was having trouble breathing, had nasal congestion, and experienced fainting spells. A CT scan showed a mass near her ear that was causing significant pressure on nearby organs. The mass was identified as an unusual type of dermoid cyst, which is a growth that can cause serious issues due to its location. This case highlights how important imaging is for diagnosing complex issues in young dogs.

Abstract
A 6-month-old, intact female Boxer presented with ongoing dyspnea, nasal congestion, cardiac arrhythmias, stertor, and syncope. A CT assessment of the head, neck, thorax, and abdomen revealed a fluid to soft tissue attenuating mass with an incomplete mineralized rim centered on the soft tissue ventral to the right tympanic bulla. Histopathologically, epithelialization was consistent with a dermoid cyst. The severe degree of mass effect caused by this abnormally and undocumented ossified structure in vital cranial cervical organs causes more systemic complications than traditional dermoid cysts. CT delineated the cyst's structure and compression/occlusion of adjacent structures.
