The usual treatment is either open microsurgical reconstruction of the foramen of Monro, or ventriculoperitoneal or ventriculoatrial shunting.…”

Two adults presented with hydrocephalus due to idiopathic obstruction of the bilateral foramina of Monro, manifesting as clinical signs of chronically elevated intracranial pressure. No inflammation was present. The primary surgical treatment was neuroendoscopic reconstruction of the right foramen of Monro. A 37-year-old man had a spontaneous perforation of the septum pellucidum. The patient required a ventriculoperitoneal shunt, although postoperative ventriculography proved free passage of cerebrospinal fluid from the lateral ventricle into the third ventricle. A 62-year-old man underwent additional septostomy and third ventriculostomy, and the neuroendoscopic intervention relieved the presenting symptoms without additional treatment. The biopsy specimens showed no evidence of malignancy in either case. Neuroendoscopic intervention is an alternative treatment in the management of hydrocephalus due to idiopathic obstruction of the foramen of Monro. The procedure is less invasive than open microsurgical reconstruction and can even avoid ventriculoperitoneal or ventriculoatrial shunting.

“…Acquired obstruction of the foramen of Monro is com moner and can occur due to tumors at or near the foramen Unilateral Hydrocephalus Pediatr Ncurosurg 1996;25:248-251 of Monro [1], cysticercus cysts [17], vascular malforma tion [2,3], post-inflammatory gliosis [4] or as a conse quence of shunt placement in the contralateral ventricle [5,10]. Congenital atresia of the foramen of Monro is rela tively rare and mostly occurs in infants or young children [6-8, 10, 11], However, a few reports mention its occur rence in adulthood [1,9,12,13]. Some of the cases of unilateral hydrocephalus due to congenital atresia of the foramen of Monro have been associated with congenital ventricular diverticulum [7,11], Usually manifesting as progressive enlargement of the head in children and raised intracranial pressure in adults, this uncommon condition is well diagnosed by a CT scan or MR1.…”

“…In some, the foramen was found to be absent [6,13], while in others it was narrow enough to just allow the choroid plexus to pass through them [1,12]. In the second group, a thin membrane appeared to occlude the normal sized foramen [1,8,9], In one of these patients, in whom histopathological examination of occluding membrane was performed, it was found to consist of a bridge of glial tissue covered with ependyma [9].…”

We report the safety and efficacy of bilateral foraminoplasty of Monro in a patient with partial occlusion of right Monro and complete occlusion of the left one. A 38-year-old man who underwent a ventriculoperitoneal shunt three years ago, and shunt revision surgery twice, presented with hydrocephalus, and was referred to us because of continuing complaints of headaches, nausea and vomiting. The primary surgical treatment of the patient was bilateral endoscopic Monro foraminoplasty. Then, the patient did not need a ventriculoperitoneal shunt, and hydrocephalus was resolved. Bilateral monroplasty in a single-session surgery can be the treatment of choice, instead of microsurgically open reconstruction of the foramen of Monro. The procedure can be less invasive, and it avoids ventriculoperitoneal shunting. KeywOrds: Foramen of monro, Foraminoplasty, Hydrocephalus, Neuroendoscopy ÖZBu yazıda, sağ foramen monroda parsiyel ve sol foramen monroda tam oklüzyonu olan hastada yapılan bilateral foraminoplastinin etkinliği ve güvenilirliği sunulmaktadır. Üç yıl önce ventriküloperitoneal şant takılan ve iki kez revizyon ameliyatı yapılan 38 yaşındaki erkek hasta, sürekli olan başağrısı, bulantı, kusma yakınması ile kabul edildi. Hastaya bilateral endoskopik foraminoplasti yapıldı. Bundan sonra hastanın şant bağımlılığı ortadan kalktı ve hidrosefalisi düzeldi. Tek seansta iki taraflı monroplasti açık yolla yapılan foramen monro rekonstrüksiyonuna alternatif bir yöntem olarak düşünülebilir. Monroplasti daha az invaziv ve şant bağımlılığını ortadan kaldıran bir yöntemdir.

Progressive Unilateral Hydrocephalus in Adults

Abstract: Unilateral dilatation of the lateral ventricle in adults is rare. We report 2 cases of unilateral hydrocephalus with obstruction at the foramen of Monro. Both patients presented with symptoms of raised intracranial pressure.
