NEURO-VASCULAR CONFLICTS IN POSTERIOR FOSSA (Abstract): The present paper presents the anatomical relationship between vessels and nerves in the posterior fossa and possible neuro-vascular conflicts, which may be the cause of diseases such as glossopharyngeal or trigeminal neuralgia, facial hemispasm, vertigo or tinnitus. Neurovascular compression syndrome refers to a group of disorders in which aberrant or tortuous vessels cause compression of a nerve, with effects of hyperexcitation and secondary neuropathy. In the posterior fossa were described especially for nerve IX, VIII, VII, V and III, and the infected vessels are generally arterial branches. For statistical purposes, sections of the 3DT2 and angioMRI TOF sections performed in patients presenting in the SUUB Imaging Department during a calendar year and correlated with clinical data were reevaluated. The posterior fossa vascular loops, so well represented by the 3DT2 sequences correlated with the source sections of the TOF sequence, should be carefully studied, since the intimate relationship between vessels and nerves in the posterior fossa is anatomical and numerous patients are asymptomatic; In a suggestive clinical context, other signs should be evaluated – deviation of the nerve tract, change in diameters, alteration of the signal, and recently – changes in the anisotropic fraction in the MR-tractography.
