[Intraorbital tumors in children. Two cases and review of the literature].

Also in childhood, the orbital cavity is a possible place for different kinds of lesions. The recent contribution of magnetic risonance imaging (MRI) enables a more accurate differential diagnosis of intraorbital pathology. The clinical and neuroradiological data of two new patients affected respectively by intraorbital meningioma and schwannoma are presented. Both patients showed exophthalmos without pain and were treated with surgery. The different etiologies of intraorbital lesions, i.e. vascular, neoplastic, inflammatory, cystic and malformative are analyzed. Sometimes the case history and neuroradiological assessment alone enable a correct diagnosis. More often, however, only surgery reveals the exact nature of the disease. The age of the patient too can represent a criteria for a possible differential diagnosis.

Child

Optochiasmatic arachnoiditis: remarks on a case of the cystic form of the disease.

In a series of 80 patients with surgically proven optochiasmatic arachnoiditis, only one case with an exclusively cystic form of the disease was found and is reported here. Certain changes, within a relatively short (6 months) period of time, of the neuro-ophthalmologic and neuroradiologic features are described in detail and discussed.

Arachnoiditis

Posttraumatic optochiasmatic arachnoiditis.

Seven cases of adhesive arachnoiditis of the optochiasmatic cistern, verified surgically, with a history of head injury are presented. Neuroophthalmologic findings consisted of impairment of visual acuity and funduscopic atrophy rather than papilledema. The visual fields showed a damage of the periaxial rather than the axial type. Neuroradiologic examinations did not consistently give the findings considered classical of optochiasmatic arachnoiditis. Surgical lysis of the adhesions has given an improvement of the visual function, or at least an arrest in its impairment, in almost all cases. It is thought that these cases still present some valid indications for neurosurgical exploration of the optochiasmatic region.
