[Vasculo-Behçet's disease with superior sagittal sinus thrombosis--case report (author's transl)].

The patient is a 30-year-old man who has suffered from recurrent attacks of tonsilitis, oral aphthae and scrotal ulcerations, erythema nodosum and thrombophlebitis. In April, 1980, he gradually developed headache and visual disturbance. On April 14, 1980, he was pointed out remarked bilateral choked disc by an ophthalmologist and then admitted to the Miyazaki Medical College Hospital. On admission to our service, he showed atypical symptoms of Behçet's disease, namely, oral aphthae and scrotal ulcerations, erythema nodosum and bilateral choked disc. Laboratory data demonstrated hyperimmunoglobulinemia, increased clotting factors and decreased fibrinolytic activity. Immunogenetically, HLA BW51 type was demonstrated. The angiograms showed complete obstructions of the superior sagittal sinus and the common trunk of the femoral artery. Histological examination of the skin lesion demonstrated atypical chronic inflammation and thrombophlebitis. A diagnosis of atypical Vasculo-Behçet's disease was made. The response to the steroid therapy was dramatic, though the fibrinolytic drugs, anticoagulants and vasodilators were not effective. Thrombophlebitis is a well recognized complication of Behçet's disease occurring in major vessels, however thrombosis of the dural sinus has rarely reported. This case may be the first one which had superior sagittal sinus thrombosis with Vasculo-Behçet's disease in literature. We discussed the mechanism of the thrombogenesis, the relationship to HLA, the coexistence of Neuro-Behçet's disease and the therapy of Vasculo-Behçet's disease.

Huge cystic craniopharyngioma with unusual extensions: a case report.

The findings on computed tomography (CT) of a huge cystic craniopharyngioma in a 3-year-old girl are described. The cyst occupied both anterior cranial fossae and a part of it extended to the region of the third ventricle which was displaced posteriorly. The tumor showed no contrast enhancement after the intravenous administration of contrast medium.

[Diagnosis of the chiasmal meningioma (author's transl)].

Not infrequently, it is difficult to differentiate the chiasmal meningioma from other suprasellar tumors, especially pituitary adenoma and craniopharyngioma. Authors examined 7 cases of chiasmal meningioma from neurological, endocrinological and neuroradiological points of view in comparison with the cases of pituitary adenoma and craniopharyngioma. As the results, the following features can be regarded as the differential characteristics of the chiasmal meningioma. 1) It was predominated in female of over 40 years of age. 2) Duration of the symptoms before admission was usually 2--3 years. 3) Disturbance of visual acuity and defect of visual field were initially unilateral in most of the cases, then extended to the other side when the disturbance of one eye had become severe. Visual field defect tended to be of irregular bitemporal hemianopsia with frequent involvement of peripheral nasal field. 4) Evidence of the endocrine disturbance were very scanty until the end stage. 5) Postero-superior elevation of A1 portion of the anterior cerebral artery in the tuberculum sellae meningioma was one of the pathognomonic features. 6) In the case of meningioma extending from tuberculum sellae to dorsum sellae or originated from dorsum sellae, PEG showed a finding of "capping on the dorsum sellae" and the tumor shadow over the posterior clinoid process took different feature from pituitary adenoma or craniopharyngioma.
