“…11 According to the cadaveric studies, the AICA loops are found within the ICA in 12.3% of human temporal bones. 12,25 However, Fkuda et al 26 claimed that the findings in the cadaver after formaldehyde fixation might be different from those in the viable state. In MR imaging studies, the incidence of AICA loops in contact with the eighth CN was nearly the same in symptomatic and asymptomatic patients (25% and 21.4%, respectively).…”

“…Although several theories have been proposed to determine the aetiology, most reports concentrate on the anatomic relation between the nerves and the juxtaposed vascular loops. Compression at the root entry or exit zone of the cranial nerves is suggested to be responsible [1,3]. However, vascular compression was also incidentally noted along the course of cranial nerves intraoperatively or in asymptomatic patients when MRI of the brainstem was performed for other reasons [4].…”

Coexistence of hemifacial spasm (HFS) and trigeminal neuralgia (TN) is a rare entity known as painful tic convulsif (PTC). Here, we present a case of right-sided HFS after which left TN developed, which is an unusual form of PTC. Both disorders were caused by bilateral vascular compression of the cranial nerves and successfully treated with botulinum toxin and carbamazepine. As PTC is benign in nature and can be treated with botulinum toxin, neuroradiological investigations should be performed for an accurate aetiological diagnosis, particularly in young patients with atypical disease manifestations.

“…This condition is defined by the International Association for the Study of Pain (IASP) as a sudden, unilateral, severe, brief, stabbing recurrent pain in the distribution of one or more branches of the trigeminal nerve [48]. The most common offending vessels are, in decreasing order of frequency, vascular loops of the superior cerebellar artery (SCA), the anterior-inferior cerebellar artery (AICA), pontine branches of the basilar artery, posterior-inferior cerebellar artery (PICA) and aberrant veins [1,44,49,50] (Fig. 17).…”

There have been unprecedented improvements in cross-sectional imaging in the last decades. The emergence of volumetric CT, higher field MR scanners and higher resolution MR sequences is largely responsible for the increasing diagnostic yield of imaging in patients presenting with cranial nerve deficits. The introduction of parallel MR imaging in combination with small surface coils allows the depiction of submillimetric nerves and nerve branches, and volumetric CT and MR imaging is able to provide high quality multiplanar and curved reconstructions that can follow the often complex course of cranial nerves. Seeking the cause of a cranial nerve deficit is a common indication for imaging, and it is not uncommon that radiologists are the first specialists to see a patient with a cranial neuropathy. To increase the diagnostic yield of imaging, high-resolution studies with smaller fields of view are required. To keep imaging studies within a reasonable time frame, it is mandatory to tailor the study according to neuro-topographic testing. This review article focuses on the contribution of current imaging techniques in the depiction of primary and secondary neoplastic conditions affecting the cranial nerves as well as on neurovascular conflicts, an increasingly recognized cause of cranial neuralgias.
