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 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.

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.

Giant serpentine aneurysm(GSA) is a giant aneurysm containing a serpentine channel which enters and exits at separate sites and is continuous with the parent vessel. This 33-year-old man with a two-year history of frontal headache presented with bitemporal hemianopsia three months before admission. Suprasellar mass of computed tomography revealed a giant(3X2.5X2cm) mixed density, mimicking a brain tumor. Cerebral magnetic resonance images showed a flow void within the mass, and this was consistent with the serpentine vascular channel demonstrated by angiography. The aneurysm was revealed by surgery involving the frontobasal interhemispheric approach, left A1 & A2 were clipped and the mass of the aneurysm was removed in toto an aneurysmorrhaphy was constructed, and to preserve the distal blood flow to the left A2, the patient made an unevenful recovery.

Symptomatic parasellar granular cell tumor is a very rare tumor. To the best of our knowledge, 43 cases was be found in the English literatures. We recently experienced a case of a parasellar granular cell tumor in a 61-year-old female who had bilateral temporal hemianopsia and severe panhypopituitarism. The tumor was composed of diffuse sheets of polygonal cells with abundant eosinophilic PAS positive granular cytoplasm. In the immunohistochemical and ultrastructural examinations, the tumor failed to show any evidence of Schwann cell or glial differentiation. These findings suggest that granular cell tumor has heterogenous cell types of origin.
