“…3 High incidences of inner ear anomalies (eg, semicircular canal dysmorphism, enlarged vestibular aqueduct, and cochlear hypoplasia) were reported in pediatric tinnitus, especially in the presence of hearing loss. 7 CT is especially useful in diagnosing any trauma-related changes of the temporal bone that may explain continuous tinnitus. Conversely, a specific etiology can be detected by imaging in 70% of the cases with pulsatile tinnitus.…”

“…Most patients with isolated continuous tinnitus do not require imaging as previous studies have shown that rarely abnormal imaging findings are encountered unless there are additional associated symptoms such as sensorineural hearing loss in which case MRI is the modality of choice 3 .

Tinnitus is defined as the perception of sound without an external source and can be categorized as either pulsatile or nonpulsatile (ie, continuous). A variety of etiologies have been reported to cause pediatric tinnitus, many with long‐lasting implications due to hearing and concentration impairments. Therefore, imaging can be an essential part of the accurate and timely diagnosis of treatable etiologies. We describe neuroimaging findings in different etiologies of pediatric tinnitus. Etiologies of pulsatile tinnitus are frequently vascular in nature and include vascular loops, congenital vascular anomalies or variants, high riding jugular bulbs with or without a jugular bulb diverticulum, idiopathic intracranial hypertension, aneurysms, internal auditory canal hemangiomas, and petrous apex cephaloceles. Etiologies of continuous tinnitus frequently affect the middle/inner ear structures and include vestibular schwannomas, cholesteatomas, trauma, Chiari malformations, and labyrinthitis ossificans. CT and MR are often complementary modalities: CT is better suited to evaluate the integrity of the temporal osseous structures and MR is better suited to evaluate the vestibulocochlear nerve and to assess for the presence of any masses or malformations. Prompt diagnosis of the etiology of tinnitus in pediatric patients is important to avoid any potential long‐term developmental impairments. In the approach to pediatric tinnitus, categorizing the symptoms as either pulsatile versus nonpulsatile and then being aware of the possible causes and imaging findings of either can assist both the clinician and the radiologist in making an expeditious diagnosis.
