The finding of an increased number of nAChRs in the regions of the epithalamus (medial habenular area) and the interpeduncular nucleus (IPN) seem to be particularly interesting in the context of a sleep disorder.
In the patients with aqueductal stenosis or obstruction, intraaqueductal CSF flow is reduced or fully absent, so endoscopic fenestration of the third ventricle floor provides an alternative quasi-physiological CSF flow pathway to the subarachnoid spaces through the interpeduncular cistern and downwards, resulting in dispersed and minimized pressure gradient on midline brain structures, surrounding cerebral aqueduct [5].
The principal MRI findings of Joubert syndrome are deep interpeduncular fossa together with a narrowing of the isthmus, thickening of the superior cerebellar peduncle, fourth ventricle deformity together with hypolplasia of the vermis, fastigumun rostral shift and sagittal vermian cleft originating from the incomplete union of the two halves of the vermis.
