doi: 10.1007/s11682-019-00187-4. Isolated medial longitudinal fasciculus (MLF) syndrome as a result of midbrain infarction is rare, and its magnetic resonance imaging (MRI) has not been reported previously. A 62‐year‐old man suddenly presented with diplopia, and consulted JA Toride Medical Center, Ibaraki, Japan. Description. Medial longitudinal fasciculus are bundle of various fibers systems that enter and leave at different levels.Its fibers interconnect the motor nuclei of cranial nerves and also connect the vestibular apparatus with ocular muscles, neck muscles, and the extrapyramidal system. The medial longitudinal fasciculus is found in the brainstem and is a set of crossed fibers with ascending and descending fibers. The medial longitudinal fasciculus links the three main nerves which control eye movements, i.e.

The vertical gaze center is at the rostral interstitial nucleus. The medial longitudinal fasciculus ascends to the interstitial nucleus of Cajal, which lies in the lateral wall of the third ventricle, just above the cerebral aqueduct.

The medial longitudinal fasciculus is basically a fine group of axons or longitudinal bundle present just a little above the midline of the brainstem or brain stem, composing of both ascending and descending batch of fibers that originates from various areas of the body.

The MLF primarily serves to coordinate the conjugate movement of the eyes and associated head and neck movements. The medial longitudinal fasciculus (MLF) is organized as a pair of white matter fiber tracts that extend through the brainstem and lie near the midline just ventral to the fourth ventricle (in the medulla and pons) and cerebral aqueduct (in the midbrain). Anja K.E. Horn, Christopher Adamczyk, in The Human Nervous System (Third Edition), 2012 Structure and Function. The rostral interstitial nucleus of the medial longitudinal fasciculus (RI) contains the premotor burst neurons, which are essential for the generation of vertical and torsional saccades (Büttner-Ennever et al., 1982; Vilis et al., 1989; Kremmyda et al., 2007). The medial longitudinal fasciculus and the medial lemniscus pathway maintain their midline location.
