We report a case of immature teratoma arising at the suprasellar region in a 18 year-old-male who presented with bitemporal hemianopsia, nausea and polydipsia. The teratoma is a rare neoplasm consisting of 0.5% to 1.2% of all intracranial tumors. The clinical presentation, radiologic finding, pathology and treatment are briefly described with a review of other cases from the literature in view of clinical features and management.

Cerebral developmental venous anomaly (DVA) is generally benign. However, we have experienced two cases of DVA causing symptoms. In the first case, the patient demonstrated DVA with venous infarction. DVA was visualized in the arterial phase using digital subtraction angiography (DSA), and was diagnosed as arterialized DVA. The second case presented as transient right homonymous hemianopia. DSA revealed venous congestion; the transient aggravation of venous congestion may have caused the symptom. DSA is useful for diagnosing the pathomechanism of symptomatic DVAs.

Neurological deficits commonly associated with anterior choroidal artery infarction (AChAI) include hemiplegia, hemisensory loss, and homonymous hemianopsia, while neuropsychological and perceptual deficits are uncommon. Prominent cognitive function impairment has rarely been reported. Here, we report a case of AChAI with prominent cognitive function impairment without motor deterioration. In contrast to the typical clinical features of AChAI, near complete and rapid motor recovery was observed, while cognitive impairment persisted despite rehabilitation therapy.

We report a 39-year-old male who had generalized tonic-clonic seizure with loss of awareness. Investigations led to a diagnosis of a left temporal lobe tumor. He underwent resection of the mass with consequent loss of brain tissue in the temporal lobe and was found to have a complete right homonymous hemianopia in the immediate postoperative period. Macular ganglion cell analysis on optical coherence tomography (OCT) showed homonymous thinning affecting the inferonasal sector in the right eye and inferotemporal sector in the left eye. This case demonstrates transsynaptic retrograde degeneration through the interruption of the inferior optic radiation, and its corresponding effect on the structure and function of the affected retinal field. Temporal lobe lesions may cause not only a homonymous visual f ield defect contralateral to the side of the lesion but also result to homonymous sectoral thinning of the macular ganglion cell complexes in both eyes located ipsilateral to the side of the lesion.

A case of cerebral paragonimiasis associated with right homonymous hemianopsia was reported in view of its rarity and a review of the related literaturs was made. The patient was 14 years old man. He had been suffering from poor visual acuity for 2 months and headache for 7 years. He had hsitory of indigestation of crayfish during measle infection. Skull x-ray revealed calcification on temporo-occipital region. He had been treated with bithionol, daily doses of 20mg/kg of body wt. for 70 days. And the rsult was improvement.

PURPOSE: To report the result of Fresnel prism application and adaptation for visual field relocation and functional vision improvement in homonymous hemianopsia patients. METHODS: Fifteen homonymous hemianopsia patients were prescribed Fresnel prism. To expand the visual field, Fresnel prism was placed base-out toward the defective field and patients were given an adaptation period of 1 month. The effects of the prism on field expansion was evaluated using Goldmann perimetry. In addition, the NEI-VFQ25 questionnaire was utilized asking patients regarding their subjective functional vision and satisfaction in daily life before and after using the Fresnel prism. RESULTS: After 1 month of Fresnel prism prescription, 53% of patients showed objective visual field expansion to the defective field of 12.5 degrees on average. Monocular or macular splitting hemianopsia patients showed more visual field expansion than binocular macular sparing hemianopsia patients. The NEI-VFQ25 score increased significantly and abnormal head position decreased or disappeared after 1 month of using the prism. However, 47% of patients failed to adapt to the prism. CONCLUSIONS: Using Fresnel prism in homonymous hemianopsia patients effectively expands the visual field, corrects abnormal head position, and improves functional vision. However, to improve the success rate, for certain patients the proper choice of prism application method, prism diopters, and constant management are necessary.

The usual manifestations of Moyamoya disease are bilateral carotid narrowing or occlusion at the carotid fork and abundant basal.vascular network with various carotid neurovascular symptoms. We report two unusual cases showing visual symptoms(bilateral cortical blindness, right homonymous hemianopsia, respectively) and angiographically vertebrobasilar and complete proximal internal carotid occlusion, with extensive parenchymal and transdural anastomosis in Moyamoya disease.
