ABSTRACT
Unilateral dilatation of the lateral ventricle is a rare condition. The most common causes are tumors of the lateral ventricles or in the area of the third ventricle, acute or chronic inflammatory gliosis, cysticercosis or congenital atresia of the foramen of Monro. We report a case of asymmetrical dilatation of the lateral ventricle in an adult patient presenting with a raised intracranial pressure syndrome caused by narrowing of the foramen of Monro which was occluded by a thin membrane. The patient underwent successful endoscopic fenestration of the Foramen of Monro.

The authors report a fifteen-year-old patient with an intraneural ganglion cyst of the common peroneal nerve, with paralysis of the anterior tibial muscles which was subacute in onset. The lesion was radically removed using microtechniques. Such a purely intraneural location has rarely been described. The use of the surgical microscope and pathological study of the peroneal articular branches allows one to reject the possible synovial origin of this lesion. The different hypotheses regarding aetiology are discussed, as well as the possible lines of treatment.
