“…The diameter of MEC ranged from 0.1 mm to 4.8 mm (mean 1.58 ± ± 0.86 mm) on the right and from 0.4 mm to 5 mm (mean 1.48 ± 0.79) on the left. More than 77% of MECs were larger than 1 mm, in contrast to Koesling et al [13] who reported over 90% of the MECs to be less than 1 mm in diameter. The mean diameter of the MF was 1.92 ± 1.02 mm on the right and 1.84 ± 0.98 mm on the left and was larger than that of the canal itself.…”

“…It was bilateral in 49.4% and unilateral in 28.3% and was more common on the left side. The relatively higher frequency reported by Koesling et al [13] was explained by Koesling's results concerning the prevalence of the bony canal, not the emissary vein [13]. However, Pekcevik et al [21] did not mention any bony canal not transmitting an emissary vein.…”

“…In contrast to anatomical studies, radiological identification of the PSS is quite uncommon (14). In animals that have a smaller degree of telencephalic growth, the PSS is the major outflow pathway of the transverse sinus, and the external jugular vein is the dominant encephalic venous drainage pathway.…”

Why should we report posterior fossa emissary veins?

Posterior fossa emissary veins are valveless veins that pass through cranial apertures. They participate in extracranial venous drainage of the posterior fossa dural sinuses. The mastoid emissary vein, condylar veins, occipital emissary vein, and petrosquamosal sinus are the major posterior fossa emissary veins. We believe that posterior fossa emissary veins can be detected by radiologists before surgery with a thorough understanding of their anatomy. Describing them using temporal bone computed tomography (CT), CT angiography, and cerebral magnetic resonance (MR) venography examinations results in more detailed and accurate preoperative radiological interpretation and has clinical importance. This pictorial essay reviews the anatomy of the major and clinically relevant posterior fossa emissary veins using high-resolution CT, CT angiography, and MR venography images and discusses the clinical importance of reporting these vascular variants.

“…Although jugular bulb variants have been associated with tinnitus, 21 the causal association of these variants with tinnitus remains controversial. 6,8,12 When one of these variants is found in a patient with pulsatile tinnitus, a search for other treatable causes should still be made.…”

SUMMARY:Tinnitus affects 10% of the US general population and is a common indication for imaging studies. We describe a sequential compartment-based diagnostic approach, which simplifies the interpretation of imaging studies in patients with tinnitus. The choice of the initial imaging technique depends on the type of tinnitus, associated symptoms, and examination findings. Familiarity with the pathophysiologic mechanisms of tinnitus and the imaging findings is a prerequisite for a tailored diagnostic approach by the radiologist.ABBREVIATIONS AV ϭ arteriovenous; AVF ϭ arteriovenous fistula; AVM ϭ arteriovenous malformation; CPA ϭ cerebellopontine angle; DSA ϭ digital subtraction angiography; IAC ϭ internal auditory canal; ICA ϭ internal carotid artery; IIH ϭ idiopathic intracranial hypertension; MD ϭ Mé niè re disease; NSAIDs ϭ nonsteroidal anti-inflammatory drugs; PSA ϭ persistent stapedial artery; TMJ ϭ temporomandibular joint.
