“…Subsequent tympanotomy or biopsy of this "mass" can result in catastrophic hemorrhage. Aberrant ICA may manifest as pulsatile tinnitus, hearing loss, vertigo, or a sensation of fullness in the ear (8,(31)(32)(33).…”

In recent years, three-dimensional (3D) multiplanar reformatted images from conventional cross-sectional computed tomographic (CT) data have been increasingly used to better demonstrate the anatomy and pathologic conditions of various organ systems. Three-dimensional volume-rendered (VR) CT images can aid in understanding the temporal bone, a region of complex anatomy containing multiple small structures within a relatively compact area, which makes evaluation of this region difficult. These images can be rotated in space and dissected in any plane, allowing assessment of the morphologic features of individual structures, including the small ossicles of the middle ear and the intricate components of the inner ear. The use of submillimeter two-dimensional reconstruction from CT data in addition to 3D reformation allows depiction of microanatomic structures such as the osseous spiral lamina and hamulus. Furthermore, 3D VR CT images can be used to evaluate various conditions of the temporal bone, including congenital malformations, vascular anomalies, inflammatory or neoplastic conditions, and trauma. The additional information provided by 3D reformatted images allows a better understanding of temporal bone anatomy and improves the ability to evaluate related disease, thereby helping to optimize surgical planning.

“…Some of the recent literature is also in favour of surgical treatment, provided that a correct diagnosis before surgery has been established 3 23. However, later reports suggested that surgery was neither necessary nor indicated because of the risk of bleeding, infection, aneurysm formation, endovascular embolisation and stroke 24 25. In general there is broad consensus that in case of an uncomplicated aberrant ICA (ie, without bleeding complications), a conservative approach with observation is recommended, since this situation is not followed by any future complications.…”

Vascular variants concerning the internal carotid artery (ICA) at the skull base level are rare. Correct workup and diagnosis in case of suspicion of such a variant are important as it mimics glomus tumours and could complicate myringotomy or middle ear surgery. We report a case of a 39-year-old woman presented with a 6-month history of right pulsatile tinnitus and aural fullness. Ear microscopy examination revealed a pale red pulsatile mass anterior to the umbo. Radiological assessment using CT and MRI/magnetic resonance angiography confirmed the diagnosis of an aberrant ICA. Interestingly, a duplication of the ICA was demonstrated, in which the enlarged inferior tympanic artery presented as the aberrant ICA, whereas a narrower collateral hypoplastic native ICA was also present. A conservative approach with regular follow-up appointments was recommended.

“…CT findings reveal such a characteristic feature as an intratympanic mass contiguous with the ICA through a dehiscence of the lateral carotid plate and dilatation of the inferior tympanic artery canal. 4 , 5 Although it has been suggested that the CT scan alone is sufficient to confirm the diagnosis of vascular anomalies, it does not always differentiate between a vascular anomaly and a highly vascularized glomus tumor. 6 MRA is a noninvasive technique compared with the conventional vascular angiography, and is useful for establishing the diagnosis in the assessment of vascular supply, in the exclusion of an aneurysm, when intervention is planned, and in follow-up of patients.…”

“…In general, it is preferable to avoid any manipulation in the middle ear after the diagnosis has been established. 5 , 15 – 17 Paralysis of the facial nerve and deafness, 16 Horner syndrome, conductive hearing loss, 18 hemiparesis, 5 aphasia, and intractable vertigo 19 had been reported because of middle ear manipulation. However, several management strategies had been described.…”

An aberrant internal carotid artery (ICA) in the middle ear space can present in 1% of the population. the clinical diagnosis can be difficult as most patients with this anomaly are either asymptomatic or have nonspecific clinical symptoms and signs. Moreover the diagnosis can easily be missed and only discovered when injurey occur to the ICA during middle ear surgey with resulting life-threatning complications. A knowledge of this anomaly and its differential diagnosis is of high importance to any practitioner dealing with otologic diseases and performing otologic surgeries. We report a 7-year-old girl with a right aberrant ICA presenting with hearing loss and review published studies concerning this disease entity presentation, diagnosis, and management.
