External auditory canal exostoses

Case contributed by Trefa Salih Hasan
Diagnosis certain

Presentation

The patient presented with discomfort in the left ear. Upon examination, swelling was noted around the ear area.

Patient Data

Age: 50 years
Gender: Female

A contrast-enhanced CT scan of the neck reveals significant enlargement of the left parotid gland, exhibiting increased attenuation. This is accompanied by reactive adenopathy in levels 2 and 3, strongly suggesting a diagnosis of parotitis.

Fatty replacement of the right parotid gland with hypertrophy of the right accessory parotid gland.

Moreover, the scan shows bilateral symmetrical calcifications in the cartilaginous part of the external auditory canal (EAC).

No calcifications were noted in the external auricle. These findings warrant close attention and may require further evaluation to ensure appropriate management.

Case Discussion

The cause of the patient's ear discomfort was proposed to be left parotitis. The bilateral symmetrical calcification of the external auditory canal's outer cartilaginous part was an incidental finding. The fact that there is no associated calcification of the external auricle makes the case more interesting than the combined calcification of the external auricle and EAC.
